Query your corpus from the tools you already use
Three steps. One corpus. Every AI tool.
Save
Paste a YouTube URL, article, PDF, or podcast. BrainTube auto-extracts transcripts, takeaways, entities, and embeddings.
Compile
Every capture joins your knowledge graph: entities extracted, related saves linked automatically. Collections and tags are there if you want them.
Query anywhere
Use it from any AI tool over MCP, the web chat, or the API. One corpus, every interface.
Not another read-later app.
Universal MCP server
Connect BrainTube to any AI tool that speaks Model Context Protocol. AI-agnostic by design.
Auto-enrichment on every save
Summaries, key takeaways, entity extraction, semantic embeddings — all on ingest.
A knowledge graph that builds itself
Postgres + pgvector graph, a real-time Auto-Linker on every save, and Personalized PageRank retrieval for questions that span captures.
Built to outlast every AI tool
Export your library as Markdown or Anki cards from Settings, or the whole corpus through MCP. Your index stays.
Capture
One-click capture, fully enriched
YouTube, web, PDFs, podcasts, Notion, voice memos, screenshots, social posts — saved and enriched in one step.
Graph
Knowledge graph that links itself
Entities extracted on ingest. The Auto-Linker connects related captures automatically as your corpus grows.
Recall
Ask, get answers that cite the exact moment
In BrainTube's chat, answers cite your saved sources, and a video citation links to the exact timestamp.
Retain
Remember what you save
FSRS spaced repetition resurfaces the right item at the right time — so saved actually means learned.
Own
Capture everywhere, own it forever
Chrome extension, PWA, Obsidian import, API keys. Export your library as Markdown or Anki cards from Settings, or the whole corpus through MCP.
MCP
