Nexus combines structured data, deep notes, and spaced repetition into one relational knowledge base. Built for power users who need to learn, not just store.
Six integrated tools in one knowledge base — no more juggling between apps.
Every row is a knowledge record with typed columns: text, code, rich text, media, references, and more.
The spaced repetition algorithm surfaces rows you're about to forget — before you forget them.
Bidirectional row links create a true knowledge graph. Navigate your concepts like a wiki.
Visualize your knowledge as an interactive node graph. Drag, arrange, and explore connections.
Monaco editor per row. Store, syntax-highlight, and review code alongside your notes.
Cmd+K full-text search across every row in every board. Find anything instantly.
