BrainTube – Your personal AI powered knowledge base

BrainTube, a new AI-powered knowledge base, launched with pricing tiers of $9 per month for Starter and $19 per month for Pro, offering features such as AI summaries, transcripts, semantic search, and chat with your library. The platform captures content from YouTube, articles, podcasts, PDFs, and other sources, compiles it into a searchable corpus, and connects to AI tools like ChatGPT and Claude via an MCP endpoint.

I — Why knowledge dies You consume more than ever. You remember less. No. 01 You forget 70% by Friday Every article, video and podcast you don't capture is an insight you'll search for later and never find. The good ideas die in browser tabs. No. 02 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. 03 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.
