What is WHY?
01
Live transcript reading
WHY? reads the video transcript in real time. Click WHY? at any moment — no pausing, no highlighting.
02
Frame capture
Pause on any frame with code. One click extracts the exact code and explains the reasoning behind every line.
03
Structured mentor output
Every explanation is broken into: what's happening, why this approach, alternatives, common mistakes, and one takeaway.
04
Claude or GPT-4o
Bring your own API key. Switch between Claude Sonnet and GPT-4o — both text and vision models supported.
They always give you the How. Rarely the Why. You end up copying code you don't actually understand.

The team
We're a small team who got tired of watching 3-hour tutorials and still not understanding what we just built. So we built the tool we wished existed.
