# Atomic

> An open-source, AI-augmented knowledge graph that connects notes, articles, and research with semantic search, wiki synthesis, and agentic chat.

Atomic is an open-source knowledge management tool that collects notes, articles, and research into an AI-augmented knowledge graph. It automatically embeds, tags, and links content to related ideas, allowing your knowledge base to organize itself as it grows. Available as a macOS desktop app, self-hosted server, iOS app, browser extension, and MCP server, Atomic runs wherever you work and keeps your data under your control.

- **Semantic Search** — *Find ideas by meaning using vector embeddings that surface related notes even when exact keywords don't match.*
- **Wiki Synthesis** — *LLM-generated wiki articles synthesize everything under a tag, with inline citations linking back to original source notes; articles update incrementally as you add more content.*
- **Agentic Chat** — *Chat with an AI that searches your notes mid-conversation, scoped to a single tag or your whole library, citing sources rather than hallucinating.*
- **Spatial Canvas** — *Visualize your knowledge as a force-directed graph where semantically related atoms cluster together; zoom, pan, and explore the topology of your ideas.*
- **Auto-Tagging** — *Drop in a note and receive a tag tree covering topics, people, places, organizations, and events — no manual folder maintenance required.*
- **MCP Integration** — *Give Claude, Cursor, or any MCP client direct access to your knowledge base to search, read, and create atoms without leaving your workflow.*
- **Atoms** — *Every piece of knowledge is an atom — a markdown note, saved article, or web clip — automatically tagged, embedded, and connected; pull content in from URLs, RSS feeds, and a browser extension.*
- **Self-Hostable** — *Run Atomic as a headless server on your own infrastructure so your data stays entirely yours.*
