About Deepmark
Deepmark is an AI-powered content search and bookmarking tool that allows users to search their saved items by actual content rather than relying on titles. It unifies content from browser bookmarks, X (formerly Twitter) bookmarks, Instagram saves, and YouTube Watch Later into a single, private library.
Instead of relying on simple keyword matches, Deepmark reads every page, transcribes video and reel audio, describes frames, and performs OCR (optical character recognition) on images. It then embeds all collected information into a searchable vector index, enabling users to find specific saves using natural, plain-language queries.
Key Capabilities & Performance:
- Deep Content Extraction: Automatically reads page text, transcribes video audio, and performs frame OCR/descriptions for comprehensive indexing.
- Multi-Platform Aggregation: Combines browser bookmarks (via a Chrome extension), X bookmarks, Instagram saves, and YouTube Watch Later in one place.
- Sub-100ms Search: Returns plain-language search results across a library of over 10,000 items in under 100 milliseconds.
- Hosted MCP Server: Provides Model Context Protocol (MCP) server support, allowing external AI agents to search your saved library directly.
