Knowledge Graph

Knowledge, taking shape

Notes keep flowing, the graph keeps growing — whole-library relations weave into one web; a topic becomes its own graph, expandable into an editable mind map.

MemoBrain · Library Graph
The whole-library graph: 1,986 entities (1,860 concepts, 76 articles, 42 notes, 5 mind maps and more) woven into one dense web by the force layout — the toolbar switches library / radial-tree / by-type views and type / community coloring, runs AI analysis and exports PNG

The whole-library graph,
auto-built

Entity relations extract straight from entries — the rules channel needs no AI, AI analysis adds more; notes accumulate, the graph grows, every relation traces to its entry.

Rules + AI, dual channel Type colors / community colors Reports saved to the library
Library · force-directed
The whole-library graph: 1,986 entities auto-extracted from entries — notes, mind maps, concepts and articles colored by type and woven by the force layout; click any entity to trace its source entries

Topic graphs,
on their own

Circle a topic and related entries gather into an independent subgraph — radial tree, type tiers and force-directed layouts on switch; topic graphs save and share with the file.

Topic graph · Current mind map → document
A topic graph gathered from one entry: the article Current mind map → document (AI) sits at the center of a radial tree — six branches (market research, product readiness, sales & distribution, launch execution…) with 22 concepts, each ring expandable in place; the legend counts 1 article + 22 concepts, with AI Analyze and Export PNG on the toolbar

One topic, one independent graphAI analysis auto-gathers · one-click re-layout

From graph,
to mind map

A selected neighborhood expands in one click into an editable mind-map page — center entity as root, neighbors as branches, relation labels carried along; AI can also sum up topics as maps, flows or architecture.

Neighborhood → map page Keep editing, semantics intact AI summaries as diagrams
Mind-map page · expanded from the graph
A graph expanded into a mind-map page: the Product Launch root with its 26 leaves spread across both sides in the butterfly layout, ready to keep editing
