Show HN: Blacklight – secret scanner for code, databases, drives, and slack https://ift.tt/hwfsyOu

Show HN: Blacklight – secret scanner for code, databases, drives, and slack We often ran pattern matching searches for secrets and keys across codebases, databases etc. Therefore, we thought about converting that workflow into a tool that we could just easily generate a SARIF report and share with our customers. Blacklight is a powerful secret, key, and sensitive data scanning tool that helps you detect and prevent sensitive information leaks in your codebase, databases, cloud storage, and communication platforms. The idea is that one can add their custom rules around their governance and compliance requirements. The platform comes with 114 matching criteria, but this can be extended easily. https://ift.tt/faA7i6j May 18, 2025 at 12:10AM

Show HN: Solidis – Tiny TS Redis client, no deps, for serverless https://ift.tt/NhGMuOz

Show HN: Solidis – Tiny TS Redis client, no deps, for serverless Hey everyone! Over the past two years I threw myself back into full-time engineering with a simple goal: write code that gives back to the community. After a lot of late-night FOMO (“AI will do it all for us, right?”) and some painful production incidents, I finally turned my weekend project into an open-source library. [ What is Solidis ? ] - Super-light (< 30 KB) RESP2/RESP3 client with zero runtime deps and first-class ESM/CJS support. - Fully tree-shakable – import only the commands you need. - Written with SOLID principles & full TypeScript typings for every command. - Designed for cold-start sensitive serverless platforms (small bundle + tiny memory footprint). [ Why I built it ] 1. node-redis & ioredis pain - ESM is still an after-thought. - Hidden deadlocks on RST, vague error surfaces. - Everything gets bundled, even commands you’ll never call. 2. I refuse to add a dependency I don’t fully understand – I literally read candidates 10× before `npm i`. 3. Serverless bills love to remind me that every KB and millisecond matters. [ Key features ] - Protocols: RESP2 and RESP3 (auto-negotiation) - Bundle size: `<30 KB` (core) / `<105 KB` (full) - Dependencies: 0 - Extensibility: Drop-in command plugins, custom transactions - Reliability: Auto-reconnect, per-command timeouts, type-checked replies [ Roadmap / Help wanted ] - Benchmarks against `node-redis` & `ioredis` (PRs welcome!) - More first-class Valkey love - Fuzz-testing the parser - Docs site – the README came first; I’d love help polishing full docs This might be my last big OSS push for a while, so stars, issues, and PRs mean the world . If Solidis saves you some cold-start time or just scratches a TypeScript itch, let me know! Repo: https://github.com/vcms-io/solidis License: MIT Thanks for reading, and happy hacking!

Show HN: Easel – Code multiplayer games like singleplayer https://ift.tt/uboGBSV

Show HN: Easel – Code multiplayer games like singleplayer For the past 3 years, I've been creating a new 2D game programming language where the multiplayer is completely automatic. The idea is that someone who doesn't even know what a "remote procedure call" is can make a multiplayer game by just setting `maxHumanPlayers=5` and it "just works". The trick is the whole game simulation, including all the concurrent threads, can be executed deterministically and snapshotted for rollback netcode. Normally when coding multiplayer you have to worry about following "the rules of multiplayer" like avoiding non-determinism, or not modifying entities your client has no authority over, but all that is just way too hard for someone who just wants to get straight into making games. So my idea was that if we put multiplayer into the fabric of the programming language, below all of your code, we can make the entire language multiplayer-safe. In Easel the entire world is hermetically sealed - there is nothing you can do to break multiplayer, which means it suits someone who just wants to make games and not learn all about networking. I've had people make multiplayer games on their first day of coding with Easel because you basically cannot go wrong. There were so many other interesting things that went into this project. It's written in Rust and compiled to WebAssembly because I think that the zero-download nature of the web is a better way of getting many people together into multiplayer games. The networking is done by relaying peer-to-peer connections through Cloudflare Calls, which means Cloudflare collates the messages and reduces the bandwidth requirements for the clients so games can have more players. I also took inspiration from my experience React when creating this language, here's how you would make a ship change color from green to red as it loses health: `with Health { ImageSprite(@ship.svg, color=(Health / MaxHealth).BlendHue(#ff6600, #66ff00)) }` There is a lot of hidden magic that makes the code snippet above work - it creates a async coroutine that loops each time Health sends a signal, and the ImageSprite has an implicit ID assigned by the compiler so it knows which one to update each time around the loop. All of this lets you work at a higher level of abstraction and, in my opinion, make code that is easier to understand. Speaking of async coroutines, my belief is that they don't get used enough in other game engines because their lifetimes are not tied to anything - you have this danger where they can outlive their entities and crash your game. In Easel each async task lives and dies with its entity, which is why we call them behaviors. Clear lifetime semantics makes it safe to use async tasks everywhere in Easel, which is why Easel games often consist of thousands of concurrently-executing behaviors. In my opinion, this untangles your code and makes it easier to understand. That's just the beginning, there is even more to talk about, it has been a long journey these past 3 years, but I will stop there for now! I hope that, even for those people who don't care about the multiplayer capabilities of Easel, they just find it an interesting proposal of how a next-generation game programming language could work. The Editor runs in your web browser and is free to play around with, so I would love to see more people try out making some games!

Show HN: AsianMOM – WebGPU Vision-LLM app that roasts you like ur mom in-browser Randomly got inspired yesterday seeing SmolVLM working on WebGPU and had the silly idea for this project. it's not perfect and super limited because of the current limitations of WebML (and admittedly, because I suck at prompting, but that's why it's Open Source haha) but it is 1.5B WORTH OF AI (SmolVLM 500M and LLama 3.2 1B) working RIGHT IN YOUR BROWSER with you not having to install anything! In fact, the whole thing is actually just an index.html that you can install and even use directly! It might be a little bit slow on first try (takes about 3 mins) when it installs models, but it caches it so it's way faster the second time (also, it's available offline after it's cached haha) Works on any modern web browser It may be a funny little project, but it's genuinely taught me so much about WebML and Vision models, and the technologies we're getting with WebML will 100% democratize AI access and make it way simpler and easier to be used everywhere :p GH Repo in case you're interested: https://ift.tt/ICPamkE https://ift.tt/DzHZnWV May 16, 2025 at 12:50AM

Show HN: Family Folder – Help your family remember everything, organise anything https://ift.tt/jVUuHAY

Show HN: Family Folder – Help your family remember everything, organise anything Hi Show HN, I’m both nervous and excited to share what I’ve been working on in the early mornings and late evenings over the past few months: Family Folder – a tool to help you and your loved ones stay connected, simplify planning, and never miss a moment. This is mostly a solo project—though I’ve leaned on ChatGPT and Upwork when I hit the limits of my technical skills. I love learning, and this has been a crash course in programming, DevOps, design, UX, and everything in between. The idea came directly from my own experience: trying to keep on top of family life, from newborns to supporting my mum’s memory, birthdays, childcare logistics, and where the insurance documents are stored. Existing tools felt too generic, too corporate, or too messy. I wanted something built for families. Stack: • Ruby on Rails 7 (via Jumpstart Pro) • PostgreSQL • Hosted on Heroku (EU region) • S3 (EU) for file uploads • (Coming soon: iOS app & AI assistant) Family Folder is private by design—you only see what you’re invited to. It’s meant to be simple enough for parents or siblings to actually use, but structured enough to avoid chaos. If this sounds useful—or if you’ve ever tried to manage a family using group chats or shared docs—I’d love your feedback. What would make something like this truly work for your family? Thanks for taking a look! – Tony https://ift.tt/Z9MoIAn https://ift.tt/Z9MoIAn May 15, 2025 at 12:27AM

Show HN: Build a free linktree alternative that skips in-app-browsers I searched for something like this and couldn’t find it. I thought, this can’t be that hard, so I built it myself. What really messed me up was that social media apps open websites inside their in-app browsers… It costs nothing to run, so it’s free for everyone. You only need to sign up if you want to create your own link page. If you just want to convert your existing link into one that automatically skips the in-app browser, you can do that without an account. I used Next.js and MongoDB.

It is a tool for working with Git repositories, more specifically, extracting and calculating current/upcoming semantic versions for your repo's tags. It is heavily inspired by the output from "git describe --tags". Why use anything else then? The output is not fully SemVer compliant and therefore I was modifying it in all my projects separately, which I wanted to avoid. Single binary, single predictable output. It does not currently have pre-built binaries, so you have to install it via cargo, but it's in the roadmap! https://ift.tt/2qmGTbY May 14, 2025 at 08:40PM

Show HN: AI-powered batch photo editor for real estate photographers I got tired of repetitive editing tasks, so I built a tool that simplifies bulk edits using text prompts and AI workflows. Now I can quickly handle things like virtual staging, changing backgrounds, adding/removing objects, adjusting brightness and exposure, color corrections, boosting contrast and clarity, fixing distortions, batch color grading and much more! But most importantly, I can do this to all selected images, tens, hundreds or more. I'm particularly interested in feedback on the workflow and UI from photographers/editors who handle large volumes of images. I've increased the free plan credits to 40 so you can edit up to 40 images, if you'd like to help me trial it out. Otherwise I'm happy to answer any questions about the implementation or roadmap. https://4ditor.com/ May 9, 2025 at 06:38AM

What is it: I wanted a fast, flexible, and focused job search tool to find new tech jobs and I didn't see anything that really fit my needs, so I built this app because you can just do things. HackerGrep indexes several recent threads on HackerNews and combines the results into a feed matching your desired search filter criteria. The system can send you daily email updates when new search results for your queries are available; opt-in search query emails are sent for 30 days and then automatically stopped. New job alert emails are batched and sent daily, so you'll get one email per alert you configure until you unsubscribe or the 30 days are up. Key features: > no banner ads / clutter. > it's free to use. > no accounts/logins needed. > advanced search syntax and full-text search. > can notify you about new jobs matching your queries via email. > the search and alert emails always show the most recent results first. (To report bugs, suggest parser/logic improvements, offer me a job, or just say hi, etc, you can find my contact info on the https://ift.tt/U9InYh8 page) You can try it from any web browser. It's optimized for desktops or tablets with a reasonable screen size but should function anywhere. https://hackergrep.com https://hackergrep.com May 10, 2025 at 11:42PM

Show HN: Limits.fyi – See what you are getting out of all your AI subscriptions Hey HN, I've personally been having a hard time keeping track of all the changes to AI subscriptions these days. Sama is always tweeting about ChatGPT usage limits being improved as they add more GPUs, nobody knows how many Claude messages you get in a day, and Windsurf just recently updated their pricing plan. It's becoming increasingly difficult to get a clear and transparent view of what you're actually getting with each subscription. This becomes especially frustrating when you run into those annoying “no more remaining message” popups right in the middle of a coding session. I've also noticed many developers suffer from what I've started calling "query anxiety”, this is when a person is always worried about hitting their usage limits, so they just end up not using these models when they actually need them. That's why I created limits.fyi which lets you view and compare usage limits for all the popular AI subscriptions in one place. You can: - See exactly what usage limits come with each plan - Filter by specific models to find which subscriptions give you access - Compare prices to find the best value for your needs - Discover new services you might not have known about I try and keep the data up-to-date, and welcome user submissions. If you notice changes or have new information, you are encouraged to contribute using the submission feature at the bottom of the page. Check it out here: https://www.limits.fyi/ I'd love to hear your thoughts and suggestions on how to make this more useful. https://www.limits.fyi/ May 9, 2025 at 12:08AM

Show HN: Cloi – free local debugging agent in your terminal https://ift.tt/ozT8BJm

Show HN: Cloi – free local debugging agent in your terminal Hey everyone! For the past two weeks my friend and I have been heads-down building Cloi, a fully local debugging agent that runs right in your terminal. You probably know the drill—every AI coding tool asks for API keys, subscriptions, and uploads your entire codebase to the cloud. Cloi does none of that: it runs entirely on your machine, with no cloud, no API keys, no subscriptions, and zero data leaving your system. What Cloi does: - Contextual error capture: Grabs your stack trace, local files, and environment to understand the issue. - Local LLM inference: Spins up Ollama on your box and generates targeted fixes—no external servers. - Safe patch application: Presents you with diffs and only applies changes when you explicitly approve. - Model‐agnostic: Ships with Phi-4 out of the box (surprisingly capable for its size!), but you can swap in any Ollama model you’ve installed. Why we built it: - Maintain full control over your code and data—ideal for security-sensitive projects - Avoid recurring subscription fees and cloud vendor lock-in - Keep your development flow entirely offline when you need it Highlights: We hit 202 stars in just 5 days, which tells us we're not the only ones who wanted this! Cloi is plug-and-play (just install and run), and we designed it to be completely unopinionated, meaning you can you whatever Ollama model you want. Get it now: npm install -g @cloi-ai/cloi If you find Cloi useful, we’d really appreciate a star on GitHub. Try it out, let us know what you think, and happy debugging! — Gabriel Cha & Mingyou Kim https://ift.tt/Rs2lPyh May 7, 2025 at 10:55PM

Show HN: X402 – an open standard for internet native payments https://ift.tt/mfjK3Nu

Show HN: X402 – an open standard for internet native payments Hi HN – excited to announce x402, initially developed by Coinbase (YC 12) x402 lets any HTTP API charge per request without issuing API keys or storing credit cards. Buyers (humans or AI agents) keep funds in their own wallet and dynamically discover compatible endpoints, call them as usual, and automatically pay a microtransaction in USDC or other tokens to settle. 90 second demo: https://www.youtube.com/watch?v=PV-L2AfLhJg Problem: Every time we want to use a new API we have to: find the service online create a developer account, copy a secret key into env vars, pre-fund or hand over a credit card This flow blocks agents even more. They can’t solve CAPTCHAs or enter credit cards. It also hurts sellers: fraud, chargebacks, onboarding friction, and marketing to humans are huge pain points. Why buyers care Zero setup – Hit a new endpoint immediately. Runtime discovery – Because every x402 service exists in a common registry, an agent can search, compare, and invoke in one loop. Self-assembling agents become practical. Easily create proxy servers – Want an endpoint that isn’t supported? You can use our proxy server template to spin up an x402-compatible instance yourself using traditional API keys, and monetize it for others wanting access. Why sellers care Reach incremental demand – Long-tail bots, side projects, one-off scripts, all of which too small for an account/signup flow, can now pay you. Micropayments without fraud – All payments settle onchain, nothing for stolen credit cards or chargebacks to reverse. Embedded distribution – instead of marketing to humans, create a compelling service meeting demand for agents and watch the requests roll in. How we got here Last year we launched AgentKit (wallets for AI agents). Tens of thousands of agents now hold onchain balances, but they can’t pay for most web services. We revived the long-unused HTTP 402 (“Payment Required”) status code and wrote a spec to make it real. Marc Andresseen calls the lack of native value transfer “the original sin of the internet,” and we see x402 as the absolution of this sin. How it works: x402 specifies a standard response body to accompany a 402 status code. This response body contains machine understandable instructions for how to pay. Payments are signature based an included as an `X-PAYMENT` header in a subsequent request to the same API endpoint. The accepting server can verify and settle payment themselves, or delegate the onchain settlement to what we call a facilitator. This means you don't have to touch crypto as a developer, you can just integrate a middleware and start receiving stablecoin payments in as little as 1 line of code. Because x402 natively traverses your existing client / server requests, it can be implemented in any language, and doesn't require webhooks, or any other complex integration. Its literally this simple: `paymentMiddleware("0xYourAddress", {"/your-endpoint": "$0.01"})` Ask HN API providers – does the one-line integration fit your stack? What’s missing?

Show HN: Automate your workflows with screen recordings and AI agents https://ift.tt/Mx6QudR

Show HN: Automate your workflows with screen recordings and AI agents Hi all, There are tons of AI agent builders out there. But let’s be honest, for most people, they’re still hard to use. Every single day, I see people struggling to create workflows with these agents and posting their requirements on Upwork. So we built Nutix. Just upload your screen recording and that’s it. Nutix watches what you do, understands your workflow, and builds it with AI agents instantly. You'll have to authorize access to underlying application for agents runs. Access over 2500+ applications and build your automations on top of it. No prompts. No coding. Just show it once , and you're done. https://nutix.ai May 6, 2025 at 03:32AM

Show HN: Tired of bloated time trackers? Here's a dead-simple, free one I built https://ift.tt/lW3wPRh

Show HN: Tired of bloated time trackers? Here's a dead-simple, free one I built Hey HN! I made TimeAnt because my dad needed a simple way to track his time at work and he didn’t like the other apps out there because they were too complicated or had way too many features. So, I built an app that just does the basics: track work hours, meetings, breaks, lunch and optionally lets you add notes - and that's it. It’s totally free, works both online and offline, and doesn’t require an account (but you can create one if you want). The goal was to keep it super simple and let you focus on tracking time without all the fluff. It also gave me a chance to learn Swift and build my first native iOS app! I’d love to hear what you think! Best, Viktor https://ift.tt/PYHIX9n May 6, 2025 at 01:21AM

Show HN: I built a synthesizer based on 3D physics and launched the product https://ift.tt/ALgGhtT

Show HN: I built a synthesizer based on 3D physics and launched the product I've been working on the Anukari 3D Physics Synthesizer for a little over two years now. It's one of the earliest virtual instruments to rely on the GPU for audio processing, which has been incredibly challenging and fun. In the end, predictably, the GUI for manipulating the 3D system actually ended up being a lot more work than the physics simulation. So far I am only selling it direct on my website, which seems to be working well. I hope to turn it into a sustainable business, and ideally I'd have enough revenue to hire folks to help with it. So far it's been 99% a solo project, with (awesome) contractors brought in for some of the stuff that I'm bad at, like the 3D models and making instrument presets/videos. The official launch announcement video is here: https://www.youtube.com/watch?v=NYX_eeNVIEU But if you REALLY want to see what it can do, check out what Mick Cormick did with in on the first day: https://ift.tt/vM3POlU I've kept a fairly detailed developer log about my progress on the project since October 2023, which might be of interest to the hardcore technical folks here: https://ift.tt/Ufe1bxu I also gave a talk at Audio Developer Conference 2023 (ADC23) that goes deep into a couple of the problems I solved for Anukari: https://www.youtube.com/watch?v=lb8b1SYy73Q https://anukari.com May 2, 2025 at 11:42PM

Show HN: Lichen – Manage and create code licenses on the CLI and with TOML https://ift.tt/bq9alxQ

Show HN: Lichen – Manage and create code licenses on the CLI and with TOML Hey! I'm Miles, I built this tool to be a fast and reliable solution for generating licenses on the CLI. Licensing has always been a point of stress for me, with how much is at stake. If I copy one from the wrong website, the version I download is the wrong one, or any number of mishaps, my whole code is at risk. We see this fiasco play out all the time. We shake our saddened heads and go on. No longer! Lichen is designed to generate licenses sensibly with three words on the CLI. `lic gen MIT`. Or in a `.lichen.toml` in your project root. Add authors/maintainers with --authors, date it with --date, license specific parts with exclude patterns and double licenses. Project big or small, it's got everything (I think). (Tell me what it's missing please). It uses SPDX licenses for correctness. Written in Rust, you'll know you're safe, and if you want to be extra cautious, feel free to create license headers on all your files (Fast too! Can do this for the entire cargo project in 22s uncached). I'm happy to answer any questions/concerns/whatever about my tool, it's my biggest project to date (And therefore my most bug-ridden...) https://ift.tt/MNXkh7r May 1, 2025 at 10:25PM

Show HN: Robot Unlock – an open-ended programming game/zachlike https://ift.tt/XUcFPoM

Show HN: Robot Unlock – an open-ended programming game/zachlike Hello, In 2010 I made an open-ended programming game based on Befunge and Brainf*k. I was young and didn't know what I was doing - coding it in AutoIT of all things and using borderless windows for sprites. Nevertheless, it was a full game and some people actually played it, sharing solutions with each other. I took it as a sign that the game had some potential - I appreciated this very much at the time. It was zachlike at its core, except that it came out earlier than SpaceChem and the term hadn't been coined yet. Years passed, I worked in the game industry, had some fun, learned a few things and eventually burned out. Meanwhile, Zachtronics kept making games and managed to define a genre, proving that there indeed was a market for such games. I'm very happy about that. Now I want to have a shot at going indie and almost 15 years later I'm launching the sequel to my 2010 game. One of my playtesters has been at it for 26 hours so I know it can be a real nerd sniper. It's a game for the type of person who loves quirky languages and optimizing their programs under extreme constraints. I have been hanging out on HN for a long time and thought some in this community might like the game. I want to keep doing this and I will as long as I can afford it. Looking forward to your questions and feedback. https://ift.tt/mq9sHkw https://ift.tt/cElORtB May 1, 2025 at 09:08PM

Show HN: I built a fun AI tour guide into Google Street View https://ift.tt/wOtvyBi

Show HN: I built a fun AI tour guide into Google Street View I love culture + travel, and one of my favorite pastimes is dropping into random streets on Google Street View. I just LOVE getting a tiny snippet into how people live, the architecture, and discovering hidden corners of places I'll probably never visit. I'm kinda weird like that. When AI came along, I started asking it to explain what I was looking at - and I learned a ton. I couldn't stop using this combo. So I built Streetwhip. It's kinda like reverse Geoguessr - instead of guessing where you are, you get educated about places as if you had a smart local guide with you. What used to be just "some random street in Buenos Aires" becomes a rich learning adventure about Argentine architecture, why things look the way you are, and stuff about the history and way of life. I've been having so much fun with it. I LOVE when I'm on an ordinary looking street and suddenly I find out there's a WILD historic story behind why the architecture is a certain way. A couple of tips: - make sure you log in! If you don't, things aren't really real-time (I had to do this because Street View's API costs can get expensive and this is just a fun hobby project for me). - play around with the categories - they're fun. I'm curating in more places over time. - the search is not perfect - when it works its magical (totally llm-driven). But sometimes it isn't. - don't use this on mobile, it kinda sucks Would love to get your thoughts on the concept and what you could see it turn into! :) P.S. Oh and one of my favorite features: radio! You get a live radio from a stream in the country (please mute it if you get annoyed - but I promise you it makes things a whole lot more immersive) https://streetwhip.com/ May 1, 2025 at 12:21AM

Show HN: Jarvis-AI, an AI Agents network that kills admin work in big corporate Cheers HN, We're Oli and Pascal, two friends from ETH Zürich. We built a network of AI Agents for large organisations, that finally gets rid of all admin work for employees. Current features are: - Schedule, move or cancel meetings (via Google Calendar or locally) - Dynamically adapt meetings according to stakeholders’ availabilities (internal communication of the agents) - Summarize incoming mails (via Gmail) - Create a project plan (command: plan XXX = [project description]) including stakeholders, timeline and cost estimate - Plan, assign and view tasks - Do all of the above via audio We believe that the network point is the core of the product. If you're planning a new project, Jarvis should not only give ideas but also propose whom to work with based on the context information of all the other Jarvises in the company. Instead of sending mails, information flow happens between the Agents and the audio feature makes it super natural to speak to your Jarvis. This is very early stage, so any advice/feedback is much appreciated :) https://ift.tt/bYgpJI6 May 1, 2025 at 12:19AM

Show HN: I made an app to learn guitar scales Hi, I'm Sergei, the creator of Guitartonic. I've been playing guitar for 17 years, but never really learned how to improvise. Most of the elaborate music theory PDFs I found online overwhelmed me, so I built a simple tool to practice basic scales and modes. It worked so well that it even inspired my roommate to pick up his guitar again. The app has been live for a few months. I had moved on to other projects and almost forgot Guitartonic existed, until the website started getting organic traffic. I noticed that people were coming to the site (somehow, 90% of the traffic is direct) and staying for four to ten minutes on average. So someone was actually using it! I even received a few heartwarming messages from users saying Guitartonic rekindled their love for playing guitar. Yesterday, someone donated $25 to support my work, which motivated me to share the project here and ask for feedback. Fellow guitarists, how did you learn scales and improvisation? What helped you the most along the way? I'd love it if you gave Guitartonic a try and let me know what you think! https://ift.tt/DrGvapi April 30, 2025 at 12:55AM

Show HN: Auto-fix your GitHub PR issues with Proton for FREE Hey HN! We just launched Proton, a GitHub app that listens to PR review comments and suggests code changes to address them. It creates a new PR based on top of your working branch, so you can simply review and merge. How is it different from other AI code review tools? Others focus on pointing out issues, whereas Proton focuses on addressing them. Although some of them can also suggest fixes, they tend to only work on nearby lines or within a single file. But real-world feedback often involves cross-file changes like “Let’s extract this to a separate component”, or “We should follow the same pattern of doing things in file X, Y and Z”. Proton has full repo context, so it can handle these kinds of feedback. Want to see it in action? Here’s a short demo: https://youtu.be/zDEfw-R2jWc , and there’s the PR shown in the demo video: https://ift.tt/maZpIX6 It’s free, takes two clicks to install, and works out of the box.

Show HN: Gemini Document Processor – Generate Th Summaries from PDF/ePub with AI Hello HN! I'd like to share Gemini Document Processor, an open-source tool I've developed. This tool uses Google's Gemini AI (their latest API) to create high-quality Thai language summaries from PDF and EPUB files. Key features include: - Support for both PDF and EPUB files - Intelligent chunking for efficient Gemini API processing - Automatic image extraction from documents - Direct integration with Obsidian (export directly to vault) - Smart retry system when errors occur (switches models/increases timeouts) - Real-time progress tracking via web interface I built this tool because I needed to read many English documents and wanted detailed summaries in Thai. If you frequently read long documents or want to build a knowledge base from multiple sources, this tool could save you significant time. The output is a well-formatted Markdown file with images and metadata, ideal for storing in Obsidian, Notion, or other PKM systems. Try it by cloning the repo and running it with Python (requires a Google Gemini API key). Feedback, suggestions, and contributions are very welcome! https://ift.tt/usKB8UL April 26, 2025 at 06:20PM

Show HN:[Opensource] AIgr.id–Polycentric Infrastructure for Open and Plural AI https://ift.tt/XJGSg1l

Show HN:[Opensource] AIgr.id–Polycentric Infrastructure for Open and Plural AI Hey HN! I'm Kanishka Nithin, founder of AIGr.id ( https://www.aigr.id ). We’re building AIGr.id — a polycentric network of independent, modular AI that can coordinate, exchange data, and compose into higher-level intelligence — all within a decentralized and plural ecosystem. Rings collective intelligence? In simpler terms: We’re trying to make it possible for people to produce, remix, operate, distribute and consume AI systems the way we use the internet— openly, collaboratively, and without needing to centralize everything into one mega-model owned by one mega-entity. Just like internet of intelligence. Today’s AI landscape is: Centralized, resource-heavy systems demand vast funding, compute, and talent—excluding much of the world. Controlled by a few powerful actors prioritizing profit over public good. Participation is limited, deepening inequality in AI benefits. Fragmented and siloed, with no open protocols for AI coordination We believe it's time to reimagine AI as collective intelligence, as shared commons — poly-centric, collaborative, composable, inclusive, and guided by values beyond profit. What’s different about our approach is that we’re not trying to build “the one true model” — we’re trying to make it easier for people to build, remix, run, and govern their own AI systems, together. We want a world where AGI doesn’t have to be monolithic — where different models, agents, and collectives can evolve side by side, coordinate, and even argue if they need to. Plural, by design. At the core of AIGr.id is OpenOS.AI, a distributed AI operating system. It is a full stack AIOS that spans everything from low-level compute orchestration to higher-level cognition, coordination, governance and economic policy. Think of it as a programmable substrate for building and running decentralized AI systems — across any infrastructure, in any topology. Developers can use shared protocols, primitives, and templates to compose AI systems — models, agents, cognitive workflows — and plug them into running grids. These grids can be public, private, federated, or even permissionless. Each grid can maintain its own sovereignty (values, rules, trust mechanisms), but still remain interoperable with others. It's designed for a world where we expect many intelligences to coexist, rather than one model to rule them all. We’re in beta and will be kicking off more extensive scale testing during our upcoming testnet phase. If this scratches an itch for you, or just want to jam on open systems — we’d love your feedback. If you're interested in joining the testnet, you can join our discord @ https://ift.tt/nfixAUg — we’d be excited to have you involved early. Docs, GitHub, and the paper are all linked at https://www.aigr.id Curious what you think — critiques, weird use cases, edge cases, counterpoints — all welcome. Our own background is what pushed us into this problem. Before this, we were a 4-person crew running one of the largest real-time AI inference workloads in India. We were doing around 500K inferences/sec across 80–90 models simultaneously, supporting 35+ public-sector use cases — mostly video analytics. We were operating across federated and private infrastructure in real time, processing millions of frames per second. We didn’t rely on cloud providers or commercial frameworks. Our market was distorted by deprioritized infrastructure investment and choosing to grow within our earnings means the only way to survive was by being ruthlessly efficient: creating frameworks that automated end to end production, operation, distribution and maintenance life cycle of AI -- everything at scale reliably without or with minimal human intervention — so four of us could actually live our lives, too. So in a way, AIGr.id was born out of necessity. It's the system we wish we had — one that treats intelligence as something modular, networked, composable, orchestratable, shareable, and governable – in a collective way. https://www.aigr.id April 22, 2025 at 11:13PM

Show HN: I made TypeScript's type inference more strict (and smarter) https://ift.tt/MbiPZXW

Show HN: I made TypeScript's type inference more strict (and smarter) As a TypeScript developer, I often found myself wishing the type system could do more—*especially when omitting or modifying deeply nested properties* inside complex objects and arrays. For instance, what if I want to remove a deeply nested field like `user.profile.email` and also something like `user.posts[ ].meta.shares` from a type? TypeScript doesn't really provide a built-in way to do that. So I built *DeepStrictTypes* — a utility that lets you *omit deeply nested keys*, even inside arrays, with full type inference and strictness. Here’s an example: ```ts type Example = { user: { id: string; profile: { name: string; age: number; email: string; }; posts: { title: string; content: string; meta: { likes: number; shares: number; }; }[]; }; }; // Remove 'user.profile.email' and 'user.posts[ ].meta.shares' type Omitted = DeepStrictOmit< Example, 'user.profile.email' | 'user.posts[*].meta.shares' >; ``` The resulting type: ```ts { user: { id: string; profile: { name: string; age: number; }; posts: { title: string; content: string; meta: { likes: number; }; }[]; }; } ``` Works great for: - Cleaning up types for API responses - Dynamically transforming deeply nested data - Improving type safety when handling structured JSON [ https://ift.tt/X2FrN68 ]( https://ift.tt/X2FrN68 ) Would love your feedback or ideas for improvements! https://ift.tt/yFqxuiR April 22, 2025 at 09:17AM

Show HN: ArTok is TikTok for research papers https://ift.tt/y9jnxFW

Show HN: ArTok is TikTok for research papers Hello everyone! I always found it hard to find new research papers outside of my usual bubble. I thought a random feed (with no recommendation algorithms) might be a fun way to explore. But I also didn’t want to waste time on completely unrelated stuff — so the idea of a fast, swipeable format came to mind. Wikitok was a real inspiration! But Arxiv and Open Review APIs weren’t as robust as Wikipedia, so I pulled the papers into a Postgres backend. Right now, I’ve indexed papers from a few recent ML conferences to see if this might be useful for others too. No signups required and it’s totally free. You can mark your favorites and add text annotations, which are saved on your device. Would love to hear your feedback! https://artok.app April 22, 2025 at 12:43AM

Show HN: Open Codex – OpenAI Codex CLI with open-source LLMs https://ift.tt/xiF3XRC

Show HN: Open Codex – OpenAI Codex CLI with open-source LLMs Hey HN, I’ve built Open Codex, a fully local, open-source alternative to OpenAI’s Codex CLI. My initial plan was to fork their project and extend it. I even started doing that. But it turned out their code has several leaky abstractions, which made it hard to override core behavior cleanly. Shortly after, OpenAI introduced breaking changes. Maintaining my customizations on top became increasingly difficult. So I rewrote the whole thing from scratch using Python. My version is designed to support local LLMs. Right now, it only works with phi-4-mini (GGUF) via lmstudio-community/Phi-4-mini-instruct-GGUF, but I plan to support more models. Everything is structured to be extendable. At the moment I only support single-shot mode, but I intend to add interactive (chat mode), function calling, and more. You can install it using Homebrew: brew tap codingmoh/open-codex brew install open-codex It's also published on PyPI: pip install open-codex Source: https://ift.tt/kjmZxN5 https://ift.tt/kjmZxN5 April 21, 2025 at 11:27PM

Show HN: HN Watercooler – listen to HN threads as an audio conversation https://ift.tt/sPapdq4

Show HN: HN Watercooler – listen to HN threads as an audio conversation Hi HN, here's something fun to play with. It takes any HN thread and turns it into an audio conversation so you can listen to the thread while doing other things. I've seen many previous attempts to turn HN threads into podcasts, but they all shared a common issue IMO: trying to reduce the very rich back-and-forth into a single-thread single-reader boring podcast. Instead, I wanted to hear the actual debate from the actual thread! So I asked Claude 3.7 to build this for me as a browser-only app. It just needs a thread URL and an Elevenlabs API key (this all remains in your browser, you can check the source code, it's only 3 files, there is no server storage of anything). To make the resulting audio experience as natural as possible, each commenter has a different voice. Commenters who appear multiple times in the thread have the same voice, and introduce themselves. A bit of context is also introduced when coming back "up" from deeply nested comments. You can play the resulting audio or download it for later listening. I'm planning to later add the ability to load multiple threads so I can have a playlist generated for listening in the gym! Any comments or improvement suggestions are appreciated! https://ift.tt/G6lQn7x April 18, 2025 at 12:24AM

Show HN: Zuni (YC S24) – AI Copilot for the Browser https://ift.tt/73P6htu

Show HN: Zuni (YC S24) – AI Copilot for the Browser Hi HN, I'm Will, and along with my co-founder George, we've built Zuni ( https://zuni.app ) - a browser extension that adds contextual AI capabilities to your browser. It understands what you're reading and working on, whether that's email, research, or anything else in your tabs. We started out building a full email client with AI built in (you might have seen that version showcased in YC’s AI Design Review - https://www.youtube.com/watch?v=DBhSfROq3wU&t=1601s ), but learned that people don't actually want to leave their existing tools - they just want them to work better. Gmail might be frustrating, but it has years of features people rely on. So we pivoted to enhance the tools people already use, rather than replace them entirely. Some specific things Zuni does today: - Analyzes emails as you read them in Gmail, identifying action items and suggesting possible responses - Lets you discuss how to handle tricky emails, almost like having a thought partner - Maintains context across your browsing session so you can ask follow-up questions naturally - Runs locally first for speed and privacy - Doesn't store chats, emails or anything sensitive in the cloud We're still early and focusing on getting the core experience right before adding more integrations. The goal is to make AI actually useful in your daily work, rather than just another "AI feature" checkbox. Would genuinely love feedback from the HN community - what would make this truly useful for your workflow? What are we missing? Happy to answer any questions about the technical implementation too. https://zuni.app April 17, 2025 at 08:45PM

Show HN: We made a VS Code extension to recreate a debugger experience from logs https://ift.tt/zIGldTC

Show HN: We made a VS Code extension to recreate a debugger experience from logs A month ago [1], we made an MCP server so Cursor can debug Node.js on its own. We emailed every person that starred our repository [2] and learnt that frontend devs really want to give Cursor access to browser logs, and that backend devs (our intended audience) do not use debuggers nearly as much as we thought. We interviewed friends across startups and discovered that they use logs to debug, because they can’t run services locally on their machine. The services (1) require too much disk, RAM, or CPUs to run locally, (2) have too many service dependencies (think microservices), or (3) are a faff to instantiate locally with a debugger. Instead, our friends instrument their services, deploy them to staging environments via Kubernetes, and then query the logs via data stores (think Grafana, Axiom.co, Google Cloud Logging, etc) or directly (think Kubernetes logs). We thought: "What if we could recreate a debugger-like experience from logs?". That would save them from browsing logs and trying to make sense of them outside the context of the code base. We looked into it and made a VS code extension that lets you (1) import logs, (2) go to the line of code associated with a log, and navigate up/down the probable call stack associated with a log. It's a prototype, but if you're interested in trying it out, we'd love some feedback!

Show HN: Particle - News, Organized https://ift.tt/xBRduWl

Show HN: Particle - News, Organized Hello HN! Particle News product engineer here. Keeping up with the news is overwhelming in an age of information overload. Particle reimagines the experience by organizing articles into comprehensive "Stories," offering clear, concise summaries to quickly grasp what matters. Today, we reached the #1 spot in "Newspapers & Magazine" on the iOS App Store—and I thought I'd share a bit of our backstory. I've been connected to this team for a long time. About 20 years ago, I shared a house with our CTO and co-founder Marcel Molina. I helped him get started with programming. Since then, Marcel has had an extraordinary career—becoming a senior staff engineer at Twitter, where he helped build foundational features like Retweets, Notifications, and Lists, and later working at Tesla on manufacturing execution systems that scaled across Gigafactories. At Twitter, Marcel worked closely with our CEO and product visionary Sara Beykpour, who led initiatives like Twitter Blue, Twitter Video, and the experimental app twttr . Sara has a background in Software Engineering and Cognitive Science from the University of Waterloo and spent over a decade at Twitter in engineering and leadership roles. In late 2022, Sara and Marcel started prototyping a news app that could reduce the cognitive and emotional burden of staying informed—by using AI to help people understand more, faster. They were soon joined by a few other former Twitter colleagues who helped shape the early concept into a working iOS application. I joined about 15 months ago to contribute across the entire stack. Since then, I've helped design and build major iOS features, rewritten our public website on Cloudflare Workers, and implemented new functionality in our Go backend, which is driven by Google Cloud's Pub/Sub architecture. What Makes Particle News Different Particle helps you navigate the news effortlessly—leveraging AI to help you understand more, faster. Some highlights: • Personalized News – Your feed is tailored to your interests. You can follow specific people, places, and things so you never miss what matters to you. • Clear Summaries – Get a quick overview or dive deeper with detailed, structured context—summarized in natural language. • Perspective Tools – Features like "Opposite Sides" and our political spectrum chart let you explore stories through multiple lenses. • Interactive Q&A – Ask questions about any story and get concise answers with sources and citations. • Audio Summaries – Use the "Play" feature to listen to your feed, specific stories, or even select articles—great for hands-free or on-the-go moments. One of the things we're most proud of is how Particle supports publishers. We've partnered with outlets like Reuters, AFP, and Fortune to host some of their content via APIs. These partners get prominent placement, and their links are highlighted in gold to stand out. This model aims to drive traffic back to publishers and reward high-quality journalism, rather than just aggregating and commodifying it. Transparency is a core value: all sources are cited, generated answers are grounded in evidence, and we take real care to prevent AI hallucinations or misleading summaries. Despite negligible marketing spend, Particle has grown to the top of its category by focusing on engagement with early users and meaningful partnerships with the media ecosystem. Coming soon: weekday mini crosswords—a new feature designed by another longtime friend of ours from 20 years back who went on to work at Twitter, lead development on Firewatch, and release his own games independently. It's incredibly fun and rewarding to be building something meaningful with old and new friends. I feel lucky every day to work alongside some of the best product, design, and engineering minds on a project we hope will help people stay engaged with democracy without burning out. https://ift.tt/fSYiRlv April 16, 2025 at 02:56AM

Show HN: Torque – A lightweight meta-assembler for any processor https://ift.tt/OhVIc8P

Show HN: Torque – A lightweight meta-assembler for any processor Hello everyone, I've been working on this project for the past few months. Torque is a meta-assembler: instead of having an instruction set built into the assembler, you use macros to build up a small language that decribes an instruction set and then you use that to write your program. It's designed to work for any microcontroller/processor architecture, you build from the bit level upwards so there aren't any assumptions around word widths, instruction formats, or endianness. I created Torque initially to write programs for a PIC microcontroller, after running into difficulties with the official assembler. I've also used it to write programs for the Z80 processor inside an old TRS-80 computer. Let me know if you try it out or have any questions! https://ift.tt/0goBcS5 April 16, 2025 at 03:16AM

Show HN: ActorCore – Stateful serverless framework that runs anywhere https://ift.tt/s3QuqwD

Show HN: ActorCore – Stateful serverless framework that runs anywhere TL;DR: ActorCore is a stateful serverless framework that can be deployed to Rivet, Cloudflare, Bun, Node.js and more. It's the easiest way to build stateful, AI agent, collaborative, or local-first applications. Hey HN! A few months ago we launched Rivet Actors ( https://ift.tt/dQ2YUpP ) as an open-source alternative to Cloudflare Durable Objects. Shortly after launching, we realized our goal is not to win over existing Durable Objects developers, but rather to grow the stateful serverless ecosystem. For context – "stateful serverless" is effectively the actor model with persistent state attached. Think Lambda functions with local storage & runs indefinitely. It's a a technology that’s gaining traction to ship faster, achieve higher performance, and outscale Postgres. The most widely used implementation is Cloudflare Durable Objects. In the process of talking to developers, we kept hearing three common concerns: - Vendor lock-in: Developers are hesitant to adopt a new programming model if there's no clear off-ramp. While it's straightforward to migrate a Postgres database, stateful serverless platforms like Rivet Actors or Durable Objects can feel locked-in due to lack of viable alternatives. - Ecosystem: Choosing a well-known database like Postgres comes with a mature ecosystem. Adopting a new model means rebuilding tooling and patterns from scratch. - Conceptual gap: Many developers have spent their entire careers designing systems with intentionally separated state and compute. A model that merges the two can feel backwards at first. After hearing these concerns again and again, we came to the conclusion that the best solution was to build a framework that works with as many platforms as possible to reduce lock-in (concern #1) and grow a shared ecosystem of tools (concern #2). It turns out, we already had a battle-tested framework built on top of Rivet Actors that we’ve been using for years. (It has a long, funky history beyond Rivet in gaming I won't get into here.) Thus, we split out the framework in to a new repo, added support for four platforms (easier said than done), and called it ActorCore. It gives developers multiple platforms to choose from when adopting stateful serverless and creates a foundation for a broader, cross-platform ecosystem. However, this still leaves concern #3: the conceptual gap. While this isn't something we can solve with a framework, I personally spend ~40% of my time working on docs, content, and examples to help resolve this. ActorCore is also panning out to be community-driven as hoped, which enables more people to try and share their experience with stateful serverless. Give ActorCore a try, read the roadmap, and let us know where we can improve documentation. If you're hesitant about trying stateful serverless, I'd love to learn more in the comments. Consider giving us a star on GitHub: https://ift.tt/GpWVUu7 https://ift.tt/CwRDHy4 April 14, 2025 at 08:27PM
