I — Why knowledge dies
You consume more than ever.
You remember less.
No. 01
Your highlights live in 14 apps
Readwise here, Notion there, Kindle somewhere, YouTube history gone. No single place an AI can actually reason over.
No. 02
AI tools cycle every six months
Today ChatGPT. Tomorrow Claude. Next quarter something new. Your knowledge base shouldn't be rebuilt every time.
II — How BrainTube works
Four volumes. One memory layer.
Vol. I
Capture anything, anywhere
YouTube, articles, podcasts, PDFs, Notion, meetings, screenshots. One save, fully transcribed, fully searchable.
Vol. II
Compile into a real corpus
Auto-summarize, auto-tag, auto-link. A graph forms behind the scenes — entities, topics, themes — grounded in what you actually read.
Vol. III
Connect to any AI
MCP endpoint exposes your library to Claude, Cursor and other MCP clients (ChatGPT support in testing). Persistent memory across every tool you'll ever use.
Vol. IV
Recall on demand
Ask in plain language. In BrainTube's chat, every answer cites the exact source: video timestamp, article paragraph, podcast minute.

Honest answers, no fine print.
Yes. Export your library as Markdown or JSON from Settings, or the whole corpus through MCP. BrainTube doesn't train models on your library. It's stored in the EU, private to your account; the AI providers we use process content to transcribe, summarise and embed it.
