What is Deepmark?

Deepmark is a browser extension that creates a private, searchable library of everything you bookmark across your browser, X, Instagram, and YouTube. It uses AI to transcribe, describe, and read every save, enabling semantic search in natural language across ~99 languages. It also offers an MCP server for AI agents to search your library.

How to use Deepmark?

Install the Chrome extension and connect your accounts. The extension imports your existing browser bookmarks and syncs new ones automatically. Enable per-site sync for X, Instagram, and YouTube to import bookmarks, saves, Watch Later, and Liked videos. Use the search bar or side panel to find anything with natural language queries. For MCP, add usedeepmark.com/api/mcp to your MCP client and sign in once.
