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.
A zero-friction, searchable notebook for your thinking
A minimalist writing surface that opens and records a thought with almost no friction, so ideas are saved before they slip away.
Every note flows into one chronological, searchable stack, removing folders and filing decisions while keeping everything findable.
Notes captured in the Chrome or Safari web app and on iOS are synced, so the same stack is available wherever you write.
A connector lets supported AI assistants read from your notebook, turning accumulated notes into usable context for AI conversations.
