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.

AI meeting agent that transcribes, summarises, and turns every conversation into searchable knowledge
Live transcription in multiple languages with speaker identification, so meeting records are accurate and attributable.
Each meeting becomes a clear summary with decisions, action items, and insights, with next steps captured and assigned automatically.
Ask questions across your meetings and connected apps to instantly produce follow-ups, reports, and content.
Get briefing documents before a meeting and real-time, personalised coaching during calls based on your history and playbooks.
