BrainTube is a platform that saves videos, podcasts, articles, PDFs and other content in a personal library, transcribes and indexes it, and lets users query the saved material via AI assistants like Claude, ChatGPT, or Cursor. Users can add content via a Chrome extension, iPhone app, or direct links, and then ask AI to retrieve specific moments or summaries. The service offers free and paid plans, includes MCP (Machine‑Content‑Protocol) integration for AI tools, and emphasizes data ownership, allowing full export of the library. BrainTube is operated by VR EXPRESS OOD, a Bulgarian company.
