About Deepmark

Deepmark aggregates bookmarks from browsers, X, Instagram and YouTube into a single private library. It transcribes page content, tweets, captions and video audio, extracts on-screen text via OCR, and generates visual descriptions and AI summaries for every save. Hybrid semantic search then matches natural-language queries against all indexed layers—spoken words, written text, visuals and metadata—across approximately 99 languages. New items are captured automatically, and the system skips duplicates while preserving folder structures. The service also exposes a read-only MCP server so AI agents can query the library directly, returning citations and context without exposing data outside the user’s account. A browser extension provides side-panel access to search and recall functions.
