Hey PH! I'm Ken, the maker of Atomic 👋 I built this because every note-taking tool I tried either buried my ideas in folders or gave me AI features that felt bolted on. I wanted something where the AI was baked into the structure itself, not a chatbot sitting on top of my notes. The feature I'm most proud of is wiki synthesis: Atomic reads all your atoms under a tag and generates a cited wiki article. Every claim links back to the source note. It's like having your own research assistant. A few fun facts about Atomic: - It's built in Rust + SQLite — the whole thing, including vector embeddings, lives in a single file - There's a built-in MCP server so Claude, Cursor, and other AI tools can query and write to your KB directly - It runs fully local with Ollama or any other OpenAI-compatible provider (LM Studio, LiteLLM, etc) No data leaves your machine Still early days but the core loop is solid. Happy to answer anything — architecture questions, roadmap, weird use cases, all fair game. 🙏

Congrats on the launch! Really love the focus on local-first and keeping everything in a single SQLite/Rust file. How does the performance hold up once the knowledge graph gets significantly large (e.g., thousands of atoms/notes)?

Coolest launch of the day fs! Btw do you see atomic as a note taking tool, a personal knowledge OS or something closer to a local-first AI assistant? Also are you using this yourself, if so is it creating an impact in your daily tasks??
