## 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.
