Show HN: AI bot that automatically processes unstructured documents Hi HN! We’re excited to share what we’ve been working on—a bot that automates the tedious task of processing unstructured documents from emails and entering them into ERPs. After many iterations, we’ve achieved 99.8% accuracy in extracting and mapping data from invoices, POs, and other documents. One surprising takeaway from this journey: building the AI was only 10% of the challenge! The real work came from handling edge cases, integrating seamlessly with various ERPs, and creating a reliable pipeline for real-world documents with messy formats. We’d love your feedback, thoughts, or questions about how we built this, the challenges we faced, or anything else. Let us know what you think!

Show HN: Open-Source Pull Request AI Reviewer https://ift.tt/ZOMI0Ub

Show HN: Open-Source Pull Request AI Reviewer Hey HN, Over the last year, I’ve reviewed more than 1000 code changes. Most of the time was spent catching obvious mistakes rather than debating complex design decisions. If we estimate ~10 minutes per review, that’s 160+ hours spent reviewing code in just one year. So I thought: could I get some of that time back using LLMs? That's why I spent the last few weekends building Presubmit.ai, an open-source AI reviewer that runs as a Github Action right when you open a Pull Request. The results so far are promising: I estimate it can reduce the review time by 50%, which in my case would mean I save 80hours (~10 working days) per year. Unlike similar SaaS solutions, the goal is not to replace the human reviewer but to highlight obvious mistakes early, spot security vulnerabilities and give more context about the change. I like to think of it as a “pre-reviewer”. Some of its features are: * Line-by-line comments * PR summarization * Title generation on request * Responds to review comments It supports all major LLMs, but I’ve found Anthropic's Claude works best for this use case. Please give it a try and share your feedback! https://ift.tt/zEDw2fl https://ift.tt/zEDw2fl November 22, 2024 at 08:28PM

Show HN: VS Code extensions that display CGM blood glucose levels in status bar https://ift.tt/lrmxKn7

Show HN: VS Code extensions that display CGM blood glucose levels in status bar As a Type 1 diabetic, I need to continuously monitor my blood glucose levels. I’ve implemented a couple of Visual Studio Code extensions that retrieve the latest blood glucose readings from your CGM and display them in your VS Code status bar. One VS code extension uses the Nightscout CGM to retrieve the blood glucose readings. It requires users to run the Nightscout application on a hosted server. A nice benefit of Nightscout application is that it works with all the major CGM devices. However, a slight drawback of this option is that it requires a hosted third party software (Nightscout) for proper functionality. I’ve also implemented a Visual Studio code extension for those (like myself) that use the Freestyle Libre CGM. This version connects directly to LibreLinkUp to retrieve the latest blood glucose readings and display them in your VS code status bar. This removes the dependency for the intermediary Nightscout application. If you are or know any software engineers living with diabetes, these tools might be helpful with diabetes management. These are tools I built for myself that help me manage my diabetes. They are completely free and open source. I am not selling anything. Users of the tools can use them without any restrictions or connection to me. I am genuinely trying to help others in the community that are software engineers and might find this helpful. If you try out any of these extensions, I’d love to hear back from you. Any feedback on improvements are very welcome and appreciated. - https://ift.tt/asUNE72... - https://ift.tt/xXcgqaz...

Show HN: Autotab – Programmable AI browser for turning web tasks into APIs https://ift.tt/w9BF7yR

Show HN: Autotab – Programmable AI browser for turning web tasks into APIs Hey HN, we're Alexi and Jonas the co-founders of Autotab ( https://autotab.com ). Autotab is a chrome-based browser you can teach to do complex tasks, with a simple API for running them from your app or backend. Here is a walkthrough of how it works: https://youtu.be/63co74JHy1k , and you can try it for free at https://autotab.com by downloading the app. Why a dedicated editor? The number one blocker we've found in building more flexible, agentic automations is performance quality BY FAR ( https://ift.tt/9bzdnoX... ). For all the talk of cost, latency, and safety, the fact is most people are still just struggling to get agents to work. The keys to solving reliability are better models, yes, but also intent specification. Even humans don't zero-shot these tasks from a prompt. They need to be shown how to perform them, and then refined with question-asking + feedback over time. It is also quite difficult to formulate complete requirements on the spot from memory. The editor makes it easy to build the specification up as you step through your workflow, while generating successful task trajectories for the model. This is the only way we've been able to get the reliability we need for production use cases. But why build a browser? Autotab started as a Chrome extension (with a Show HN post! https://ift.tt/p6EmFJA ). As we iterated with users, we realized that we needed to focus on creating the control surface for intent specification, and that being stuck in a chrome sidepanel wasn't going to work. We also knew that we needed a level of control for the model that we couldn't get without owning the browser. In Autotab, the browser becomes a canvas on which the user and the model are taking turns showing and explaining the task. Key features: 1. Self-healing automations that don't break when sites change 2. Dedicated authoring tool that builds memory for the model while defining steps for the automation 3. Control flows and deep configurability to keep automations on track, even when navigating complex reasoning tasks 4. Works with any website (no site-specific APIs needed) 5. Runs securely in the cloud or locally 6. Simple REST API + client libraries for Python, Node We'd love to get any early feedback from the HN community, ideas for where you'd like the product to go, or experiences in this space. We will be in the comments for the next few hours to respond! November 21, 2024 at 01:52AM

Show HN: Browser-based website builder powered by LLMs I wanted to share what I've been working on - it's a AI site builder that runs in the browser powered by WebGPU and OnnxRuntime-Web. I have got the following all working to varying degrees: - text to code generation - image to code generation - microphone to text to code generation If you are on Mac for instance, it will interface directly with your GPU to power the LLM interface. It only requires downloading the models, and then everything after that is offline. It's not even close to as powerful as Claude or ChatGPT, but I like the idea of having the LLM run directly on your machine. I just did this for fun, but I am looking for a new role if anyone's hiring - https://ift.tt/6apzsqR ! More technical insight: - I also got the Typescript / React app to compile itself in the browser via a service worker https://ift.tt/1cgJ9mt but took it offline due to some oddities with service workers. - A lot of the new speech models are a lot better than anything built into your phone / computer. I wonder when more computers will have them built in. - I added a CSP to the iframe only because I was worried about spamming sites since I update the iframe anytime a new token comes in. So if you have an image on the page it will get reloaded every time the iframe is updated. Otherwise there would be no reason for it. https://ift.tt/gQZ62Xf November 20, 2024 at 01:54AM

Show HN: Archgw: open-source, intelligent proxy for AI agents, built on Envoy https://ift.tt/GwO0Tlx

Show HN: Archgw: open-source, intelligent proxy for AI agents, built on Envoy Hi HN! This is Adil, Salman, Co and Shuguang and we're excited to introduce archgw [1], an open source intelligent proxy for agents built on Envoy [2]. Arch moves the critical but crufty work around safety, observability, and routing of prompts outside business logic. Arch is a uniquely intelligent infrastructure primitive, engineered with purpose-built fast LLMs [3] for tasks like intent detection over multi-turn, parameter identification and extraction, triggering single/multiple function calls, and offers convenience features to auto dispatch LLM calls for summarization based on data from your APIs via system prompts configured in archgw. Today, the approach to build a smart production-ready agent is weaving together a large set of mono-functional opinionated libraries, adding extra layers like LLM-based preprocessing to determine things like relevance and safety of the user's prompt (e.g. applying governance and guardrails). Once past that stage, developers must extract relevant information from the user prompt to determine intent, extract parameters as necessary, package relevant tools calls to an LLM to trigger a backend API to execute particular domain-specific task. etc. After all that is done then only are developers ready to trigger an LLM call for summarization and must manage upstream error handling and retry logic themselves. Not to mention, if they want to experiment with multiple LLMs or move between LLM versions, they have to write crufty undifferentiated code. This entire experience is slow, error prone, cumbersome, and not specifically unique. Prior to building archgw, the team spent time building Envoy [2] at Lyft, API Gateway at AWS, specialized search and intent models at Microsoft Research and worked on safety at Meta. archgw was born out of the belief that several rules based mono-functional tools should be converged into a multi-functional infrastructure primitive designed for prompts and agents. We built archgw on the highly popular, battle-tested open source proxy Envoy and re-imagined it for prompts and agents. For this we had to build blazing fast LLMs [3] that can handle crufty, ahead-in-the-request-path type of work in handling and processing prompts that are sent to an agent, so that developers can focus on what matters most: building fast personalized agents without the unnecessary prompt engineering and systems integration work needed to get there. Here are some additional details about the open source project. arghw is written in rust, and the request path has three main parts: * Listener subsystem which handles downstream (ingress) and upstream (egress) request processing. * Prompt handler subsystem. This is where archgw makes decisions on the safety of the incoming request via its prompt_guard primitive and identifies where to forward the conversation to via its prompt_target primitive. * Model serving subsystem is the interface that hosts all the lightweight LLMs engineered in archgw and offers a framework for things like hallucination detection of our these models We loved building this open source project, and our belief is that this infra primitive would help developers build faster, safer and more personalized agents without all the manual prompt engineering and systems integration work needed to get there. We hope to invite other developers to use and improve Arch. Please give it a shot and leave feedback here, or at our discord channel [4] Also here is a quick demo of the project in action [5]. You can check out our public docs here at [6]. Our models are also available here [7]. [1] https://ift.tt/8uDVWLg [2] https://ift.tt/ZF9YTDf [3] https://ift.tt/EP4J3Cv...

Show HN: Windsurf – Agentic IDE At Codeium, we've been building AI-powered extensions for a while (we first launched our VSCode extension with autocomplete a little over 2 years ago!), but we've always thought there would come a day where we would hit the limits of what could be achieved within existing IDEs, so we decided to build our own: Windsurf (yes, it's yet another VSCode fork :) We've stuffed a lot of cool features into Windsurf—a super fast autocomplete model, an inline diff generation experience that feels truly native, but we're most proud of Cascade, which is an evolution of the sidebar chat experience that many other extensions have. Cascade can perform deep reasoning on your existing codebase, access a vast array of tools that allow it to run terminal commands and find relevant files, and it's omniscient of all the actions that the user has taken independent of invoking the AI. (You can for example, start implementing a change manually and just ask Cascade to "continue"). We've been using Cascade internally at Codeium on our actual production codebase, and we're getting actual value from it. We hope everyone here does too! You can find a bunch of demos of Cascade on our website but I want to show one that I made myself using Cascade to solve an interesting cryptography challenge: https://youtu.be/LbYepFmVB20 Cascade was able to explain the problem to me, install some libraries needed to interact with the challenge, give me some pointers towards a solution, and implement an attack that I described to it all by itself. https://ift.tt/ZoFMJ6U November 13, 2024 at 10:39PM

It pains me to see startups getting ripped off when the availability of technologies such as Clickhouse makes real time analytics almost a trivial feature to implement in 2024. We think it's time to end the carnage and democratize the technology. We set ourselves a high bar: we don't want to build another DocSend - we want it to be a far more superior product and also 10x cheaper. After a couple of months of work, I'm proud to share with you Peony - a first preview into what we believe will be the future of file sharing. In addition to the analytics and security features you'd expect coming from DocSend, we built Peony to be flexible and adaptable across all your file sharing needs and give you the ability to deeply personalize your file share per recipient. I'd love to hear what you think? We are the Prometheus stealing fire from the guarded Olympian mountains. Help us win the rebellion. https://peony.ink/ November 12, 2024 at 12:58AM

I have owned SICP for a decade or more and am giving it another go. I (re)started it last weekend using the DrRacket editor, which is fine, but I spend most of my time in vs code. It was a jarring to use another editor. So, in an evening of delightful bikeshedding, I now have a setup that should let me work through SICP in vs code. I thought I'd share this in case someone else is interested or has any feedback. This is a barebones configuration with a lightly tested installation script that works on my machine!

Show HN: RL Agent that can auto-optimize your LLM prompts Hey everyone! Along with my team, I've developed a reinforcement learning system that automatically optimizes LLM prompts, complete with a visualization feature to track both prompt structure and learning progress over time. Take a look here: https://ift.tt/OMoGPt5... Check out our website too: https://ift.tt/cYspTyi In terms of how this visualization works: The RL Prompt Optimizer employs a reinforcement learning framework to iteratively improve prompts used for language model evaluations. At each episode, the agent selects an action to modify the current prompt based on the state representation, which encodes features of the prompt. The agent receives rewards based on a multi-metric evaluation of the model's responses, encouraging the development of prompts that elicit high-quality answers.

Show HN: ChatGPT for calorie tracking. Frictionless diet and exercise tracking Hi, I'm Steve and I've built this mobile app to solve my very long-standing problem of not consistently using any calorie tracking apps due to the poor UX (many clicks, too much friction).

Show HN: Autotab Instruct – Claude Computer Use with Guardrails for Reliability https://ift.tt/8vETZnR

Show HN: Autotab Instruct – Claude Computer Use with Guardrails for Reliability Hi HN, We’ve built a desktop app to create highly reliable AI agents that use a computer with mouse and keyboard. Until last week, we had tried many different approaches to open-ended agentic features but none of them had met our reliability bar. With Anthropic’s Computer Use this finally changed, and we just shipped a feature we’re calling Instruct. Instruct allows users to create agentic blocks as part of a larger Autotab skill that provides the structured logical flow to keep the automation on track. If you haven’t had a chance to try Computer Use yet, it is an impressive leap from the last generation of vision models (e.g. gpt4o struggles with relative positions, let alone coordinates). At the same time, it is still not good enough to be given a prompt and let loose. One of the big surprises to us early on was just how much intent specification is required for most real world workflows to run reliably. What looks at first like a simple form filling task usually turns out to have dozens of edge cases and super specific, hidden rules. Even human employees need to be shown how to perform these tasks, and then refined with question-asking + feedback over time. We wanted to build a tool for specifying intent, and iterating with the model to make it reliable enough for real work. - Automations run on top of an action scaffold, which works kind of like a very fuzzy programming language with strict types. This gives the model a high level plan that guides execution, and makes it easy to break out discrete steps to get the reliability you need. (Interestingly, this has also proven useful not just for the agent, but also for the human trying to create, verify and edit the automation.) - When the model is unsure it asks for clarification. For example, if you are in editing mode and the model thinks that an element looks meaningfully different than before, it will ask you to verify that it is the same element. - The agent has access to a memory system that lets it recall information from past runs as well as instructions and feedback from the user. Here's a short video of Autotab Instruct in action: https://ift.tt/xOpDGTj?... We’d love to hear what you think! November 1, 2024 at 10:26PM

Show HN: Shimmer – ADHD-adapted body doubling https://ift.tt/PxVteil

Show HN: Shimmer – ADHD-adapted body doubling I’m Chris, one of the co-founders of Shimmer. In 2022, following my ADHD diagnosis, I launched Shimmer ( https://shimmer.care ), a 1:1 ADHD Coaching for adults (HN launch here: https://ift.tt/wUqHdDI ). One problem we discovered while running 1:1 coaching is that people weren’t able to actually follow through (in real life) on the ideas they came up with during their weekly sessions with their coach. There is a concept called body doubling that’s popular within the ADHD community—it’s basically getting things done in the presence of other people. The positive accountability is proven to work. However, our members told us they tried other body doubling solutions or attempted to organize it themselves in real life but none of the solutions stuck. So we reverse engineered productive moments our members described, paired with scientific backing of what motivates ADHD-ers, and designed an online body doubling experience for our coaching members that provides a safe but productive space for them to get things done between weekly sessions. A few of the motivators we infused into the traditional body doubling experience were 1) newness/novelty — each session has a different guided experience in the break like breathwork or stretching, 2) urgency — there’s a large visible pomodoro timer on the top left that counts down from 25 min, 3) community — the shared space is ADHD-friendly, and has a mood check-in & sharing functionality built in so you don’t feel alone, 4) accountability — there’s a task list where each time you check something off, it notifies the group, and you can view others’ as well if they opt in. Here’s a video walking through the product experience: https://ift.tt/AtKdlLq Our body doubling was created and iterated alongside thousands of people with ADHD on our coaching platform over 9+ months of building & iterating with them. We’re excited to unveil this experience. If you have ADHD (or executive functioning challenges), we’d love for you to check out coaching & body doubling and give us critical feedback. Shimmer’s pricing: $140/mo. for Essentials plan (15-min weekly sessions), $230/mo. for Standard plan (30-min weekly sessions), $345/mo. for Immersive plan (45-min weekly sessions); all plans start with an additional 25% off the first month, HSA/FSA-eligible. The reason why the price is so high is that this is not a self-guided app or SaaS tool. You’re matched with a real, credentialed coach (not AI) and since ADHD coaching is not reimbursed in the US, the price is hard for us to bring down because the largest cost component is the coach’s compensation. *We know these prices are still expensive for many people with ADHD. Here are the actions we’re taking: (1) we offer needs-based scholarships and aim to have 5% of members on them at any time, (2) we often run fully sponsored scholarships with our partners—over 60 full ride scholarships and 100 group coaching spots have been disbursed alongside Asian Mental Health Project, Government of Canada, and more, and (3) we have aligned our coaching model alongside Health & Wellness Coaching, which is expected to be reimbursed in the next years. If there are ways we can further drive down the cost, please reach out to me directly at chris@shimmer.care. https://ift.tt/wrI1cVm October 31, 2024 at 10:57PM

Show HN: Routing24 – Free route optimization in the browser Hi HN! I built Routing24 to make route optimization easier and accessible for small businesses and solo drivers. With Google Maps, you can plan routes between a few locations for free, but it doesn’t support efficient multi-stop planning, handling multiple vehicles, or adding specific business rules like delivery time windows. Many tools offer route optimization for around $30 per vehicle per month, but Routing24 provides it completely free. Optimization happens fully on the client-side, using your device’s resources instead of cloud servers. The interface is simple for now: you can import/export using Excel, and there’s a web UI to edit and view imported data and optimized routes. Data is saved or uploaded anywhere, and one browser tab runs one optimization. Map data comes from OpenStreetMap, and the solver is built in C++/WASM, using public domain algorithms. I’d love to hear any feedback as I keep developing it. Thanks, and I hope it’s useful! https://routing24.com October 30, 2024 at 08:06PM

Show HN: Let's Play (Voice AI) Ball – A Baseball Strategy Game My 8 year old son is obsessed with baseball. It’s unfortunate because 1) I deeply love lacrosse (I was the leading scorer my sophomore year for UC Davis! Never miss an opportunity to say it!), 2) I don’t know much about baseball, and 3) he’s a diehard Yankees fan. Although I can’t do anything about his team affiliation or the current 3-0 Yankees deficit in the 2024 World Series, I can do something about teaching him baseball strategy -- despite knowing little about baseball myself. I built this Voice AI game for him to learn more about baseball strategy. In the game, the Voice AI describes a baseball scenario, and the caller has to describe what the defensive player should do. To try it out, call (530) 203-8359. While my son is obsessed with baseball, I’m equally obsessed with Voice AI. Voice AI is eating the world. We’re seeing Voice AI consume pre-existing call volume (e.g., lead qualification calls, customer surveys, medical appointment setting) and creating a deluge of new call volume enabled by the Voice AI medium (e.g., role playing for professional development ( https://solidroad.com/ ), an AI that introduces you to people with similar interests ( https://www.boardy.ai/ ), and, yes, voice-first baseball games to make you feel like a better dad). If you’re building in Voice AI and are as enthralled with Voice AI as me, check out what we’re building ( https://ift.tt/9Dc654B ) when we’re not building fun voice-enabled AI applications.

Show HN: Trench – Open-source analytics infrastructure https://ift.tt/KRroPwI

Show HN: Trench – Open-source analytics infrastructure Hey HN! I want to share a new open source project I've been working on called Trench ( https://trench.dev ). It's open source analytics infrastructure for tracking events, page views, and identifying users, and it's built on top of ClickHouse and Kafka. https://ift.tt/TirJE6A I built Trench because the Postgres table we used for tracking events at our startup ( http://frigade.com/ ) was getting expensive and becoming a performance bottleneck as we scaled to millions of end users. Many companies run into the same problem as us (e.g. Stripe, Heroku: https://ift.tt/dKfEr1P ). They often start by adding a basic events table to their relational database, which works at first, but can become an issue as the application scales. It’s usually the biggest table in the database, the slowest one to query, and the longest one to back up. With Trench, we’ve put together a single Docker image that gives you a production-ready tracking event table built for scale and speed. When we migrated our tracking table from Postgres to Trench, we saw a 42% reduction in cost to serve on our primary Postgres cluster and all lag spikes from autoscaling under high traffic were eliminated. Here are some of the core features: * Fully compliant with the Segment tracking spec e.g. track(), identify(), group(), etc. * Can handle thousands of events per second on a single node * Query tracking data in real-time with read-after-write guarantees * Send data anywhere with throttled and batched webhooks * Single production-ready docker image. No need to manage and roll your own Kafka/ClickHouse/Nodejs/etc. * Easily plugs into any cloud hosted ClickHouse and Kafka solutions e.g. ClickHouse Cloud, Confluent Trench can be used for a range of use cases. Here are some possibilities: 1. Real-Time Monitoring and Alerting: Set up real-time alerts and monitoring for your services by tracking custom events like errors, usage spikes, or specific user actions and sending that data anywhere with Trench’s webhooks 2. Event Replay and Debugging: Capture all user interactions in real-time for event replay 3. A/B Testing Platform: Capture events from different users and groups in real time. Segment users by querying in real time and serve the right experiences to the right users 4. Product Analytics for SaaS Applications: Embed Trench into your existing SaaS product to power user audit logs or tracking scripts on your end-users’ websites 5. Build a custom RAG model: Easily query event data and give users answers in real-time. LLMs are really good at writing SQL The project is open-source and MIT-licensed. If there’s interest, we’re thinking about adding support for Elastic Search, direct data integrations (e.g. Redshift, S3, etc.), and an admin interface for creating queries, webhooks, etc. Have you experienced the same issues with your events tables? I'd love to hear what HN thinks about the project. https://ift.tt/j0BYkNb October 25, 2024 at 07:37PM

Show HN: I built EstateLead AI – lead generator boosting agent productivity 10x https://ift.tt/n1Dk0dH

Show HN: I built EstateLead AI – lead generator boosting agent productivity 10x As a former real estate agent, I discovered a critical pain point in early 2023. Every day, I spent 3-4 hours manually copying leads from Zillow - phone numbers, emails, and property details. This tedious process was stealing valuable time I could have spent with clients. I realized this wasn't just my problem. Thousands of agents were stuck in this same time-consuming routine, manually gathering leads one by one. There had to be a better way. Over the next a months, I faced numerous challenges building EstateLead AI: - Ensuring reliable data extraction - Maintaining compliance with data privacy regulations - Creating an intuitive interface for non-technical users - Scaling the system to handle thousands of requests After countless iterations and feedback from 50+ beta testers, I'm excited to launch EstateLead AI with these key features: Key Features: - One-click lead extraction from Zillow listings - Up to 18,000 leads per month with phone numbers - Export to Excel/CSV for easy CRM integration - Coverage for both US and Canadian markets - Built-in compliance with data protection rules - Simple browser extension interface The tool has already helped 600+ agents save 40+ hours per week on lead generation. Early users report a 10x increase in their prospecting efficiency. I'd love for the HN community to try it out and share your thoughts.

Show HN: Mdx – Execute your Markdown code blocks, now in Go Hey HN! I recently came across makedown here on HN and loved the concept. Wanting to learn Go, I thought this could be a great starter project - so I started working on my own Go implementation, which I’m calling mdx ( https://ift.tt/yTxzahO ). Key Features: - Define dependencies between commands - Supports shebangs - Ability to pass arguments to code blocks Would love feedback and thoughts! Ref. makedown: https://ift.tt/7vCjTgs .

Show HN: Jist searches JSON 3x faster than jq https://ift.tt/dNwUuKt

Show HN: Jist searches JSON 3x faster than jq Hi HN, jist is a JSON path search tool that feels like accessing a JavaScript object. It’s 3x faster than jq for the same use case, and over 2000x more memory efficient when searching a 3.3GB file for the last element (jist reads data in chunks so has constant space use). It doesn’t implement pattern matching yet. A feature I’m looking to add is generating a full JSON schema using the same streaming approach so stay tuned! Any feedback and feature requests are more than welcome https://ift.tt/MwHirhx October 26, 2024 at 06:55PM

Show HN: Create Waitlist Pages https://ift.tt/3Z5uFyd

Show HN: Create Waitlist Pages I decided to launch FastWaitlist because I was facing a problem with validating my own product ideas. I noticed the lack of tools that: 1. Let you create waitlist pages fast (always faced complicated page builders) 2. Have conversion optimized templates (we have 5 and we're planning to add more) 3. Support custom domains That's exactly why I launched FastWaitlist. It has solved a huge pain point for me and I hope it'll do the same for you. https://ift.tt/Dc3S1Bi October 25, 2024 at 11:47PM

Show HN: Infinite SCP Generator https://ift.tt/bjUvTS9

Show HN: Infinite SCP Generator I work at .txt, the Outlines maintainers, and did this as a fun side project. I used Outlines to structure language model output in the format of an SCP entry. SCP entries have a specific structure. It's easy to get a language model to generate these structures via JSON without fail -- no parsing errors, no trailing commas, no missing brackets. Outlines ensures that all text generated will follow the SCP structure. We're also testing an internal structured text API, and figured this might be a good way to test out repeated, regular calls. Entries are generated at midnight and uploaded to a simple website. Check out the resulting entries here: https://ift.tt/5IC0zSL https://ift.tt/yhm6Fwr October 24, 2024 at 11:46PM

Show HN: Open-source low-code email editor Hey HN, Chandler from Dittofeed ( https://ift.tt/CqmKzwn ). We just added low-code functionality to our open-source email template editor. The editor features a Notion-inspired “/” command interface for inserting new blocks. You still have the option of using MJML or HTML, but we wanted to give everyone an easier option for creating primarily text-based emails. We have a live demo of the editor which you can access here (just hit the “Create Template” button): https://ift.tt/q4lRrJ9 Since this is the first iteration of the feature, we’d love to hear your thoughts and feedback on how we can improve it.

Show HN: OVault – Simple and Local OTP Management for iOS/macOS https://ift.tt/sQ8Wlt3

Show HN: OVault – Simple and Local OTP Management for iOS/macOS OVault is a super simple iOS and macOS app that lets you store and view your OTP codes for two factor authentication. I found that my personal favourite OTP app Authy seemed to be getting worse with each iOS release. Its usability has never been great, and iOS 18 meant that it lost its Home Screen Widget that let me view my OTP codes without opening the app. I decided to switch to another app, then became frustrated that I couldn't easily export my secrets from Authy. Of course I'm sure there are good security related reasons for this, but I didn't want to migrate all my OTPs just to end up in the same situation in the near future. I also didn't want to have to trust another external service with my OTP secrets being stored on their servers (irrational I'm sure). The obvious answer for this would be to use Apples new 2FA support in Keychain, however the usability for this outside of Safari autofill isn't great either. So that's the long-winded reason for why I built my own OTP app. I hope that anyone else feeling the same way will find this app useful. Of course, learning how TOTP codes works was a nice bonus for my curiosity. OVault stores your OTP metadata inside your devices Keychain, so that you don't have to trust any new service with your data. Unless you have iCloud Keychain enabled, this also means your secrets never leave your device. If you do have iCloud Keychain enabled, your OTP metadata will be synced between all your devices, which ensures your data is never lost. The app provides widgets that you can put in your iOS Home Screen or macOS Notification Center so that you can view your OTPs without opening the app. This was my favourite feature of Authy (until iOS 18). To the best of my knowledge, OVault supports all TOTP codes that are compliant with RFC6238 [1], which means that it supports codes of lengths 6-8, three hash algorithms (SHA1, SHA256, SHA512), and all suggested time periods (15s, 30s (default), 45s, 60s). Exposing these options means that it supports a wide array of TOTP codes, even those that seem non-standard (like those used in HID Approve MFA and other "proprietary" 2FA solutions). Your OTP secrets are yours, so OVault allows you to view the saved secret on demand. This gives you enough information to import your OTPs to any other authenticator you want, avoiding lock-in to a specific app. It's worth mentioning that this app isn't designed to be "super high" security. If you already use Keychain for your passwords, you'll find yourself storing OTP secrets and passwords in the same database. Depending on your threat model, this may not be ideal. For me, I'm happy with threat model this leaves me with (I personally prefer to trust fewer parties), but everyone should critically evaluate if this works for them. If you want to evaluate the app, here's how to add a sample OTP: 1. Tap the "+" button in the toolbar, then tap "+ Manual" 2. Switch to the "From URL" tab 3. Paste in the following URL: otpauth://totp/Example:alice@example.com?secret=JBSWY3DPEHPK3PXP&issuer=Example I'd love to hear any feedback, this has been a fun side project and it would be fun to see if it's useful at all to anyone else.
