The Problem

Why Learning on YouTube Currently Sucks.

The best technical talks and lectures in history are free on YouTube. But capturing the insights is a battle against cognitive overload.

⚠️ Friction #1

The Tab Graveyard

You have 47 YouTube tabs open. You swore you'd watch them "this weekend." Instead, they eat your Mac's battery and RAM until Chrome crashes and they vanish forever.

💸 Friction #2

The $240/Year SaaS Tax

Web summarizers charge $20 every single month to run basic AI calls. Over 3 years, you've paid $720+ for a tool that breaks without internet and hoards your notes in their cloud.

🗑️ Friction #3

Superficial "AI Slop"

Generic AI bots spit out 3 superficial bullet points. They skip code snippets, miss architectural diagrams, hallucinate key concepts, and omit clickable timestamps.

The Economics

The Math Is Embarrassingly Simple.
