Transcript & footage credit
“The universe was behaving much more strangely than we imagined. And that instead of coasting out at the constant speed forever or slowing down, it in fact is accelerating. Huge, unexpected mystery.”

Analysis
AI finds the hooks
The AI watches and reads the entire video, then surfaces the moments most likely to hold attention. Each hook comes with a virality score, the transcript quote it is built on, and the reasoning — so you know why it was picked, not just where.
Scored hooks with reasoning

Studio
You adjust captions, transitions, and trim
Pick the hooks you want, style the karaoke captions (position, size, colors) with a live preview, set transitions between clips, and trim edges until the pacing feels right. The AI proposes; you decide what ships.
Full creative control
