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.

On-device AI memory for AI researchers
Save a finding from a paper, ML blog post or news article as a "bit" straight from the page you are reading.
The AI that indexes and recalls your bits runs locally and does not send data to any server.
All bits are stored and indexed on your own machine rather than in the cloud.
Look up what you saved even without an internet connection.
