Show HN: CoolWulf AI – A personal AI assistant built in Go, optimized for macOShttp://coolwulfAI.comHey HN,I've been building CoolWulf AI (https://coolwulfai.com), a self-hosted personal AI assistant. After seeing OpenClaw blow up, I wanted to share what I've been working on — a different approach to the same problem.*Why I built this:*I tried OpenClaw and found the Node.js/TypeScript stack heavy for what's essentially a local agent. pnpm, Node 22+, React — lots of moving parts. I wanted something that's a single binary, zero runtime dependencies, and feels native on macOS. So I built it in Go.*How it's different from OpenClaw:*- *Single binary, no runtime needed.* Download, set your API key, run. No Node.js, no pnpm, no build step. One ~100 MB binary. - *Built in Go.* Fast startup, low memory footprint, compiles to a native executable. No garbage collector pauses from a JS runtime sitting in the background. - *macOS-native integrations.* Deep AppleScript-based control of Apple Notes, Reminders, Calendar, Terminal.app, and WeChat desktop. These aren't browser hacks — they use the natFeb 17, 2026 5:32 AM

Show HN: Mindweave – AI-powered personal knowledge hub with semantic searchhttps://www.mindweave.space/Hi HN,I built Mindweave to solve a problem I kept running into — I'd save bookmarks, notes, and links across different apps, then never find them again when I actually needed them.Mindweave lets you capture notes, links, and files in one place. The interesting part is what happens after: - Semantic search — find content by meaning, not just keywords. "That article about improving deep work" finds it even if those words don't appear in the content. Powered by pgvector cosine similarity on Gemini embeddings. - AI auto-tagging — Gemini generates tags on save, so you don't have to organize anything manually. - Knowledge Q&A — ask questions about your saved content using RAG. Retrieves relevant pieces, feeds them as context to Gemini, returns a grounded answer. Stack: Next.js 15 (App Router, Server Actions), PostgreSQL 16 + pgvector, Google Gemini (text-embedding-004, 768d), Drizzle ORM, Auth.js v5, Tailwind/shadcn. Deployed on Cloud Run.

Show HN: GHOSTYPE – AI voice input that learns your writing stylehttps://news.ycombinator.com/item?id=46971643Hello HN,I’m the creator of GHOSTYPE.I built this because I wanted a voice input workflow that didn't feel like talking to a chatbot. I wanted something that felt like a "neural extension" of my keyboard.It’s a macOS-native app that sits between your voice and your active window. Here is what it actually does:The Core Input Workflow:Push-to-Talk & Smart Send: Hold a global shortcut to speak. It detects the active app to determine the correct send method (e.g., Cmd+Enter for Slack vs Enter for Discord).Inline Editing: You can format while speaking. Need a line break, a specific spelling, or a bulleted list? You just say it, and it handles the formatting inside the sentence before outputting."Call Ghost": Post-processing commands (translate, polish, expand) are available immediately after speaking, before the text is typed out.The Experimental Stuff (WIP):1. Ghost Twin (Style Transfer): I call this a "Virtual Personality Engine" (a bit pretentious, I know). It analyzes your local writingFeb 11, 2026 6:35 AM

I can't help thinking that it's so obvious we are almost at the very top of this bubble - but here it feels like the majority of HN doesn't think like that...Yet just in 2026 we had:- AI.com was sold for $70M - Crypto.com founder bought it to launch yet another "personal AI agent" platform, which promptly crashed during its Super Bowl ad debut.- MoltBook-mania - a Reddit clone where AI bots talk to each other, flooded with crypto scams and "AI consciousness" posts. 250,000+ bot posts burning compute for what actual value?

Show HN: Tangs.dev – Upload → Save to Drive → Share with Friendshttps://tangs.devHello!I’m the maker of Tangs, a simple way to upload a file, save it directly to your Google Drive, and share it instantly with a temporary link.I built Tangs because sharing files through Drive often feels more complicated than it should be: messy permissions, long links, and too many steps.As a developer, I often prepare documents or presentation materials on my work PC before meetings. But when I need to use those files in a conference room or on another computer, it always becomes a hassle.In a rush, I’d end up emailing attachments to myself, uploading to random shared folders, or dealing with access issues and cluttered links — all just to move a file quickly. It felt unnecessarily frustrating and restrictive, especially for something so common during day-to-day work.That pain point is what led me to build Tangs: a faster, cleaner way to get a file onto the right machine and share it instantly.With Tangs:- Upload once- Save to your own Google Drive- Share in seconds- Minimal GooglFeb 9, 2026 2:39 PM

Show HN: OpenSymbolicAI – Agents with typed variables, not just context stuffinghttps://news.ycombinator.com/item?id=46876687Hi HN,We've spent the last year building AI agents and kept hitting the same wall: prompt engineering doesn't feel like software engineering. It feels like guessing.We built OpenSymbolicAI to turn agent development into actual programming. It is an open-source framework (MIT) that lets you build agents using typed primitives, explicit decompositions, and unit tests.THE MAIN PROBLEM: CONTEXT WINDOW ABUSEMost agent frameworks (like ReAct) force you to dump tool outputs back into the LLM's context window to decide the next step.Agent searches DB.Agent gets back 50kb of JSON.You paste that 50kb back into the prompt just to ask "What do I do next?"This is slow, expensive, and confuses the model.THE SOLUTION: DATA AS VARIABLESIn OpenSymbolicAI, the LLM generates a plan (code) that manipulates variables. The actual heavy data (search results, PDF contents, API payloads) is stored in the Python/runtime variables and is never passed through the LLM context until a specific primitive actually neFeb 3, 2026 8:19 PM

I can't read anymore. My eyes glaze over after two paragraphs.So I went down a rabbit hole looking for scientifically proven ways to actually focus while reading:- Encoding info visually AND aurally reduces mind wandering by up to 40% - Retrieval practice (asking questions) beats passive re-reading every time - Background music matched to content keeps you in flowCouldn't find anything that did all this. So I built it myself:- Synced text highlighting while you listen - Talk with your book; pause and ask "wait what does that mean?" and it knows exactly where you are (won't spoil what's ahead) - Adaptive background music that matches the mood of each pageI've removed all slop. No flashy features, no gamification etc. etc. Just reading on steroids for fried brains, likeFeb 2, 2026 11:49 AM

Show HN: Nono – Kernel-enforced sandboxing for AI agentshttps://nono.shHey HNLuke here.I built nono and got it out quick then I expected, in response to the openclaw carnage, but its use is beyond openclaw.The problem: AI agents execute code on your machine. Prompt injections, hallucinations, or compromised tools can read ~/.ssh, exfiltrate credentials, or worse. Application-level sandboxes can be bypassed by the code they're sandboxing.I have been around security for a long old time now (i started something called sigstore a few years back) and have seen this pattern so many times before.The solution pitch: nono uses OS-level isolation that userspace can't escape:Linux: Landlock LSM (kernel 5.13+) macOS: Seatbelt (sandbox_init) After sandbox + exec(), there's no syscall to expand permissions. The kernel says no.What it does:nono run --read ./src --allow ./output -- cargo build nono run --profile claude-code -- claude nono run --allow . --net-block -- npm install nono run --secrets api_key -- ./my-agentFilesystem: read/write/allow per directory or file NeFeb 1, 2026 9:35 PM

Show HN: Self-hosted RAG with MCP support for OpenClawhttps://github.com/2dogsandanerd/ClawRagI've been using OpenClaw to control my home server via WhatsApp, but it couldn't access my documents. Instead of uploading my private contracts to OpenAI, I built ClawRAG – a self-hosted RAG engine that connects to OpenClaw via MCP (Model Context Protocol). Now I can ask "What did the contract say about liability?" and get cited answers, not hallucinations.Most RAG systems are either too complex for a solo dev's home setup or they rely on cloud-hosted vector stores. I needed something that runs in a single Docker container, understands messy PDFs (tables!), and integrates natively as a "tool" for agents rather than just another REST endpoint.## Technical Deep Dive### Why MCP instead of REST? I chose the Model Context Protocol (MCP) because it provides structured schemas that LLMs understand natively. The MCP server exposes `query_knowledge` as a tool, allowing the agent to decide exactly when to pull from the knowledge base vs. when to use its built-in memory. It prevents "tool-drift" Feb 1, 2026 4:45 PM
