Deepmark
Deep search for bookmarks — finds saves by what's inside, not the title
Visit website →About
Deepmark gathers browser bookmarks, X bookmarks, Instagram saves, and YouTube lists into one private library — and reads what is actually inside them. Pages are fetched and read, videos and reels are transcribed in about 99 languages, frames get described and OCR'd, and every page gets a screenshot described the way you'd remember it.
Everything is embedded for hybrid semantic search, so a vague memory like "the reel with the one-pan pasta trick" finds the save even when nothing in it says pasta. Saves become searchable in about 90 seconds; searching a 10,000-item library returns in under 100 milliseconds.
It also ships a hosted MCP server, so Claude, Cursor, or ChatGPT can search your library and cite the results. One plan: $10 a month or $84 a year.
