Nothing I think
gets lost.

Notes, links, half ideas and 2am shower thoughts. Captured in seconds, connected on their own, recalled with a single question.

Recall instantly.

No folders to maintain, no tags to remember. The structure shows up on its own.

  1. 01$ /capture

    Capture

    Type it or say it on the phone, from the middle of the bar. A task lands in the inbox, a note in the vault, in under a second.

  2. 02$ nodes + edges

    Connect

    Mail, meetings, people, trips and notes become nodes, and every link between them an edge. Claude files the rest, and every write it makes can be undone.

  3. 03$ brain_search

    Recall

    Search everything at once, or ask Claude, which reads the same store through the same API. Answers come with the notes they came from.

// recall

Ask,
don't search.

Claude reads everything you have saved and answers like someone who was there, with receipts.

  • every answer cites its notes
  • remembers who said what, and when
  • every write Claude makes can be reverted
