Stop copying. Start understanding.

WHY? is a Chrome extension that explains the reasoning behind code in YouTube tutorials — not just the syntax. Be first to know when we launch.

No spam. One email when we ship.

You're on the launch list.

We'll send you a personal email the moment WHY? goes live. You'll be among the first 100 users.

Your AI mentor, inside YouTube.

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.
