TL;DW
One-keystroke YouTube → Gemini
The problem
A 40-minute video might hold two minutes of answer. Getting an AI summary means copying the URL, opening a chat tab, retyping the same prompt — every single time.
The build
Too Long; Didn't Watch: on any YouTube video or Short, press Alt+G. TL;DW opens Gemini, injects a saved prompt profile with the video URL, and submits it. Built-in profiles cover summary, research, learning, tutorial extraction, and moment finding — with a clipboard fallback if Gemini's composer can't be filled.

Process notes
- 1
Deliberately zero-surface: no backend, no analytics, no YouTube OAuth, no Gemini API key. History stays in Chrome local storage, and Gemini responses are never read or stored.
- 2
Every build auto-bumps the patch version and copies to the Windows folder Chrome loads from — the version in the popup proves a reload actually picked up the new build.

Roadmap: a per-search "curiosity field", transcript-aware prompts, and a BYO-key API mode only if response saving earns the extra surface area.
