v1.22.2 — Desktop, Server & iOS

Start building your 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.
