Show HN: An open-source extension to chat with your bookmarks using local LLMs https://ift.tt/6eNA5li

Show HN: An open-source extension to chat with your bookmarks using local LLMs I read a lot online and constantly bookmark articles, docs, and resources… then forget why I saved them. Also was very bored on Valentines, so I built a browser extension that lets you chat with your bookmarks directly, using local-first AI (WebLLM running entirely in the browser). The extension downloads and indexes your bookmarked pages, stores them locally, and lets you ask questions. No server, no cloud processing, everything stays on your machine. Very early but it works and planning to add a bunch of stuff. Did I mentioned is open-source, MIT licensed? https://ift.tt/MOtixdn February 15, 2026 at 10:31PM

Show HN: Microgpt is a GPT you can visualize in the browser https://ift.tt/WXZkdMi

Show HN: Microgpt is a GPT you can visualize in the browser very much inspired by karpathy's microgpt of the same name. it's (by default) a 4000 param GPT/LLM/NN that learns to generate names. this is sorta an educational tool in that you can visualize the activations as they pass through the network, and click on things to get an explanation of them. https://ift.tt/KHJqQnx February 16, 2026 at 12:10AM

Show HN: GitHub "Lines Viewed" extension to keep you sane reviewing long AI PRs https://ift.tt/smEZ0JR

Show HN: GitHub "Lines Viewed" extension to keep you sane reviewing long AI PRs I was frustrated with how bad a signal of progress through a big PR "Files viewed" was, so I made a "Lines viewed" indicator to complement it. Designed to look like a stock Github UI element - even respects light/dark theme. Runs fully locally, no API calls. Splits insertions and deletions by default, but you can also merge them into a single "lines" figure in the settings. https://ift.tt/CTHEFiB February 14, 2026 at 12:49AM

Show HN: Azazel – Lightweight eBPF-based malware analysis sandbox using Docker https://ift.tt/ADuCTlz

Show HN: Azazel – Lightweight eBPF-based malware analysis sandbox using Docker Hey HN, I got frustrated with heavy proprietary sandboxes for malware analysis, so I built my own. Azazel is a single static Go binary that attaches 19 eBPF hook points to an isolated Docker container and captures everything a sample does — syscalls, file I/O, network connections, DNS, process trees — as NDJSON. It uses cgroup-based filtering so it only traces the target container, and CO-RE (BTF) so it works across kernel versions without recompilation. It also has built-in heuristics that flag common malware behaviors: exec from /tmp, sensitive file access, ptrace, W+X mmap, kernel module loading, etc. Stack: Go + cilium/ebpf + Docker Compose. Requires Linux 5.8+ with BTF. This is the first release — it's CLI-only for now. A proper dashboard is planned. Contributions welcome, especially around new detection heuristics and additional syscall hooks. https://ift.tt/lRLu0H9 February 15, 2026 at 12:37AM

Show HN: Moltis – AI assistant with memory, tools, and self-extending skills https://ift.tt/HiZg3X0

Show HN: Moltis – AI assistant with memory, tools, and self-extending skills Hey HN. I'm Fabien, principal engineer, 25 years shipping production systems (Ruby, Swift, now Rust). I built Moltis because I wanted an AI assistant I could run myself, trust end to end, and make extensible in the Rust way using traits and the type system. It shares some ideas with OpenClaw (same memory approach, Pi-inspired self-extension) but is Rust-native from the ground up. The agent can create its own skills at runtime. Moltis is one Rust binary, 150k lines, ~60MB, web UI included. No Node, no Python, no runtime deps. Multi-provider LLM routing (OpenAI, local GGUF/MLX, Hugging Face), sandboxed execution (Docker/Podman/Apple Containers), hybrid vector + full-text memory, MCP tool servers with auto-restart, and multi-channel (web, Telegram, API) with shared context. MIT licensed. No telemetry phoning home, but full observability built in (OpenTelemetry, Prometheus). I've included 1-click deploys on DigitalOcean and Fly.io, but since a Docker image is provided you can easily run it on your own servers as well. I've written before about owning your content ( https://ift.tt/bAU6w2t ) and owning your email ( https://ift.tt/Qpj8tum ). Same logic here: if something touches your files, credentials, and daily workflow, you should be able to inspect it, audit it, and fork it if the project changes direction. It's alpha. I use it daily and I'm shipping because it's useful, not because it's done. Longer architecture deep-dive: https://ift.tt/n6JxMg4... Happy to discuss the Rust architecture, security model, or local LLM setup. Would love feedback. https://www.moltis.org February 13, 2026 at 12:45AM

Show HN: Pgclaw – A "Clawdbot" in every row with 400 lines of Postgres SQL Hi HN, Been hacking on a simple way to run agents entirely inside of a Postgres database, "an agent per row". Things you could build with this: * Your own agent orchestrator * A personal assistant with time travel * (more things I can't think of yet) Not quite there yet but thought I'd share it in its current state. https://ift.tt/cgWH7yr February 12, 2026 at 11:12PM

Show HN: Unpack – a lightweight way to steer Codex/Claude with phased docs https://ift.tt/uv8XihO

Show HN: Unpack – a lightweight way to steer Codex/Claude with phased docs I've been using LLMs for long discovery and research chats (papers, repos, best practices), then distilling that into phased markdown (build plan + tests), then handing those phases to Codex/Claude to implement and test phase by phase. The annoying part was always the distillation and keeping docs and architecture current, so I built Unpack: a lightweight GitHub template plus docs structure and a few commands that turns conversations into phases/specs and keeps project docs up to date as the agent builds. It can also generate Mintlify-friendly end-user docs. There are other spec-driven workflows and tools out there. I wanted something conversation-first and repo-native: plain markdown phases, minimal ceremony, easy to adapt per stack. Example generated with Unpack (tiny pokedex plus random monsters): Demo: https://apresmoi.github.io/pokesvg-codex/ Phases index: https://ift.tt/NO6AqMH... I’d love feedback on what the “minimum good” phase/spec format should be, and what would make this actually usable in your workflow. -------- Repo: https://ift.tt/xtSWjI1 https://ift.tt/xtSWjI1 February 12, 2026 at 01:17AM

Show HN: Deadlog – almost drop-in mutex for debugging Go deadlocks https://ift.tt/ESrDhy3

Show HN: Deadlog – almost drop-in mutex for debugging Go deadlocks I've done this same println debugging thing so many times, along with some sed/awk stuff to figure out which call was causing the issue. Now it's a small Go package. With some `runtime.Callers` I can usually find the spot by just swapping the existing Mutex or RWMutex for this one. Sometimes I switch the mu.Lock() defer mu.Unlock() with the LockFunc/RLockFunc to get more detail defer mu.LockFunc()() I almost always initialize it with `deadlog.New(deadlog.WithTrace(1))` and that's plenty. Not the most polished library, but it's not supposed to land in any commit, just a temporary debugging aid. I find it useful. https://ift.tt/uW8iU4P February 10, 2026 at 11:14PM

Show HN: HN Companion – web app that enhances the experience of reading HN https://ift.tt/nRj5Jyh

Show HN: HN Companion – web app that enhances the experience of reading HN HN is all about the rich discussions. We wanted to take the HN experience one step further - to bring the familiar keyboard-first navigation, find interesting viewpoints in the threads and get a gist of long threads so that we can decide which rabbit holes to explore. So we built HN Companion a year ago, and have been refining it ever since. Try it: https://ift.tt/caJRUVo or available as an extension for Firefox / Chrome: [0]. Most AI summarization strips the voices from conversations by flattening threads into a wall of text. This kills the joy of reading HN discussions. Instead, HN Companion works differently - it understands the thread hierarchy, the voting patterns and contrasting viewpoints - everything that makes HN interesting. Think of it like clustering related discussions across multiple hierarchies into a group and surfacing the comments that represent each cluster. It keeps the verbatim text with backlinks so that you never lose context and can continue the conversation from that point. Here is how the summarization works under the hood [1]. We first built this as an open source browser extension. But soon we learned that people hesitate to install it. So we built the same experience as a web app with all the features. This helped people see how it works, and use it on mobile too (in the browser or as PWA). This is now a playground to try new features before taking them to the browser extension. We did a Show HN a year ago [2] and we have added these features based on user feedback: * cached summaries - summaries are generated and cached on our servers. This improved the speed significantly. You still have the option to use your own API key or use local models through Ollama. * our system prompt is available in the Settings page of the extension. You can customize it as you wish. * sort the posts in the feed pages (/home, /show etc.) based on points, comments, time or the default sorting order. * We tried fine tuning an open weights model to summarize, but learned that with a good system prompt and user prompt, the frontier models deliver results of similar quality. So we didn’t use the fine-tuned model, but you can run them locally. The browser extension does not track any usage or analytics. The code is open source[3]. We want to continue to improve HN Companion, specifically add features like following an author, notes about an author, draft posts etc. See it in action for a post here https://ift.tt/FJ1DZmX We would love to get your feedback on what would make this more useful for your HN reading.

Show HN: VillageSQL = MySQL and Extensions https://ift.tt/JuFMXyH

Show HN: VillageSQL = MySQL and Extensions INSTALL EXTENSION vsql-complex; CREATE TABLE t (val COMPLEX); Look, MySQL is awesome [flamewar incoming?]. But the ecosystem has stagnated. Why? No permissionless innovation. Postgres has flourished because people can change the core of the database (look at pgvector and pg_textsearch), without having to get their changes accepted upstream. (This, btw, is what powered GitHub's early success: you can fork a repo and make changes without needing the owners' approval) VillageSQL is a tracking fork of MySQL (open source, ofc) that adds an extension framework: * Drop-in replacement * Add custom data types and functions (with indexes coming soon) * we wrote example extensions (vsql-ai, -uuid, crypto, etc.) * you have a better idea for an extension * my CEO submitted a Show HN post but linked to the announcement blog; help me show him hackers want code first * I'm particularly proud of the friendly C++ API to add custom functions (in func_builder.h) That link again is https://ift.tt/rfDZqiT (Oh, and I get to work with the former TL of Google's BigTable and Colossus, so we care about doing databases Right) https://ift.tt/rfDZqiT February 5, 2026 at 09:05PM
