knowledge graph
Open source. Self-hosted. Your data stays yours.
Also available as a self-hosted server or iOS app
Not just a note-taking app — a knowledge graph
Notes, articles, web clips, feeds — everything is automatically embedded, tagged, and linked to related ideas. Your knowledge base organizes itself as it grows.
Semantic Search
Find ideas by meaning, not just keywords. Vector embeddings surface related notes even when the words don't match.
Wiki Synthesis
LLM-generated wiki articles synthesize everything under a tag, with inline citations linking back to your original notes.
Agentic Chat
Chat with an AI that searches your notes mid-conversation — scoped to a single tag or your whole library. It cites sources, not hallucinations.
Spatial Canvas
Visualize your knowledge as a force-directed graph. Semantically related atoms cluster together. Zoom, pan, and explore the topology of your ideas.
Auto-Tagging
Drop in a note and get back a tag tree — topics, people, places, organizations, events. No folders to maintain. The taxonomy builds itself.
MCP Integration
Give Claude, Cursor, or any MCP client direct access to your knowledge base. Search, read, and create atoms without leaving your workflow.
Your knowledge, synthesized
Atomic generates wiki articles from everything under a tag — your notes, saved articles, web clips. Every claim is backed by inline citations linking to the source. Articles update incrementally as you add more.

Find by meaning
Search across everything in your knowledge base by concept, not just keywords. Vector embeddings surface related ideas even when the words don't match.
Learn moreThe building blocks
Every piece of knowledge is an atom — a markdown note, a saved article, a web clip. Write in a full editor, or let Atomic pull content in from URLs, RSS feeds, and browser extensions. Each atom is automatically tagged, embedded, and connected.
