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. *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 brain to ChatGPT, Claude, Cursor and any agent. Persistent memory across every tool you'll ever use.

Vol. IV

### Recall on demand

Ask your brain in plain language. Get answers cited to the exact source — video timestamp, article paragraph, podcast minute.
