Capture micro-notes, organised with AI
Capture short notes in seconds, so fleeting ideas, quotes and to-dos are recorded before they disappear.
An AI layer helps organise and make sense of your notes, so a growing pile of micro-notes stays searchable and useful.
Tag notes by topic and browse them as themed streams, turning scattered jottings into browsable knowledge collections.
Share notes or collections with others through feeds, useful for teams, study groups and communities.
A visual knowledge base that turns scattered sources into a worldview you can build on
Split PDFs, web pages, YouTube videos, podcasts and Readwise or Zotero items into cards and read deeper through every citation.
Turn any goal into a personalised course and process readings with AI help before arranging ideas on the board.
Give your knowledge a structure that can be reworked as you learn, using nested tags and properties rather than flat folders.
Query your knowledge base from Claude Code, ChatGPT, Codex or Grok Bot through the plugin, MCP server and CLI.
