Deep search every bookmark, save, and video you've ever collected
A Chrome extension imports your whole bookmark tree, then keeps browser bookmarks, X bookmarks, Instagram saves and YouTube Watch Later/Liked lists syncing in the background, skipping anything already stored.
Every save is read inside and out — page and post text, spoken audio in around 99 languages, sampled video frames, OCR of on-screen text, and a visual description of the page.
Describe a memory in natural language and hybrid semantic plus keyword search scans every layer of every save, working across roughly 99 languages.
Each item gets an AI summary and tags so half-remembered saves are easy to resurface and organize without manual filing.

The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
