Trace: Knowledge Graph Notes

Write a note. Trace does the rest.

Trace reads your notes and automatically finds the people, places, and ideas you mention. It connects related notes into a visual knowledge graph — so you can see patterns and relationships you didn't know were there.

No tagging. No linking. No organizing. Just write naturally, and watch your graph grow.

HOW IT WORKS

Write a quick note about anything — a meeting, an idea, something you read. Trace extracts entities automatically using on-device intelligence: names become People, locations become Places, topics become Concepts.

Notes that share entities connect automatically. "Coffee with Sarah" links to "Sarah's MacBook" links to "Meeting at Blue Bottle" — without you lifting a finger.

Open the graph canvas and see your entire web of knowledge laid out as an interactive, physics-driven visualization. Drag nodes, zoom in, tap a node to highlight it and its neighbors in amber.

WHAT MAKES TRACE DIFFERENT

Visual knowledge graph — not just a list of notes. See how everything connects at a glance.

Five layers of entity detection — manual marking, global rules, Apple Intelligence (on-device LLM), NLP tagging, and a built-in dictionary of 5,000+ names, places, and concepts. Your entities are found, not missed.

Completely private — everything runs on your device. No accounts, no cloud processing, no tracking. Your thoughts stay yours.

Considered design — black ink on cream paper across every screen. Visual hierarchy in the graph comes from node size and opacity, not color noise. Tap a node and the only color in the app — amber — picks out its neighborhood.

Smart graph canvas — force-directed physics, degree-sized nodes, semantic similarity edges, subgraph focus mode, and a minimap for navigation.

Timeline view — see your notes chronologically with entity chips inline. Filter by day, week, or month.

Tags and templates — organize with custom tags, start notes from templates (Meeting, Journal, Idea, Reading).

Home screen widget — capture a thought in one tap, with a live mini-graph of your saved layout.
