Ontology Graph

A real second brain.

Every time you save, the concepts and relationships in what you wrote get woven into a knowledge graph. The agent follows this web of knowledge to answer and to work. No folders, no tags. Search behaves like memory, not plain keyword matching.

How search works

An index that surfaces what's related — it follows connections to recall like memory, not just matching keywords. All on your device.

01

Detected as you save

The moment you save a note, the concepts and relationships in your sentences are detected and added to the knowledge graph. The graph grows right away, with no separate cleanup.

02

Grab threads from many angles

It starts from what you're looking for, reaching in several directions at once — from notes that share words to notes that mean something similar.

03

Recall by following connections

From those starting points it follows relationships, synonyms, hierarchies, and mentions to surface what's related too. It finds things by association, like memory, not by plain matching.

What the graph does for you

Search that recalls like memory

Not plain matching — it follows connections to surface what's related by association. All on your device.

Connecting the same things on its own

It quietly links the same thing written under different names. Always reversible, and it never merges away your originals.

A self-naming map of topics

It clusters similar topics automatically and gives each cluster a name and a summary. It even shows the paths that connect one topic to another, at a glance.

3D graph view

Drag to spin notes colored by topic, scroll to zoom, and explore how your knowledge is woven together in 3D.

A portable graph file

Export the knowledge graph as a portable, standard-format file and compare changes at a glance. The graph is something you can regenerate, so you can rebuild it from scratch anytime.

Vocabulary that grows with your notes

It learns the terms and phrasings you use in your notes, so it recognizes the same concept consistently. Your wording converges instead of scattering.

Grow a second brain from your own notes

Local-first. Markdown is the easiest way to edit the graph. As you write, a knowledge graph grows beneath it.
