An AI knowledge base that emails you what you read yesterday
Save web pages, text notes, images, YouTube videos and podcasts into a single personal knowledge base, so your reading and watching live in one place.
Ask questions to your saved knowledge base and get answers grounded in the material you have collected rather than the open web.
Explore a visual map of how your items relate and mine the collection for connections, themes and blind spots you might have overlooked.
Get a daily newsletter of what you read yesterday, or listen to it as a podcast. A lightweight way to review and retain what you have learned.
Local-first visual note-taking on an infinite canvas with mind maps and knowledge-base AI
Place cards anywhere on the canvas, then switch to mind-map or database views to see structure without reorganizing your notes.
Highlight and annotate PDFs on the canvas and take timestamped notes on videos; highlights automatically become reference cards.
Semantic search, knowledge-base Q&A, and content retrieval find the right notes; chat works with your own model API key.
Files live on your device by default and sync across devices through WebDAV, S3, OneDrive, or Baidu Netdisk — your credentials stay yours.
