How it works

A model of your mind.

Not a note-taking app. Not a task manager. A system that understands how you think — and evolves with you.

Capture anything

Text, URLs, files, voice. Zero friction. Everything lands in your Inbox — the AI handles the rest.

AI extracts what matters

Every capture is analyzed for beliefs, decisions, goals, and constraints. No tagging. No folders. Just thinking.

Knowledge graph

Entities and relationships surface automatically. See how your ideas connect across time and context.

Layered memory

Working, episodic, semantic, archival. Your memory is structured — not a flat search box.

The loop

Capture → Extract → Evolve.

01

Capture

Drop anything into the Inbox — notes, URLs, articles, thoughts. No structure required.

02

Extract

AI distills beliefs, decisions, goals, and constraints from every capture automatically.

03

Connect

Entities link into a knowledge graph. Your thinking becomes navigable and searchable.

04

Propose

Agents surface conflicts, patterns, and opportunities. You approve or dismiss.

The difference

"Why not just use Notion or ChatGPT?"

Notion / ChatGPT / Obsidian

Static storage — captures but doesn't understand
You do the organizing, always
No model of your beliefs or decisions
Context resets every conversation
You manage the graph manually
No agents, no proposals, no evolution
