YouTube Chapter Generator

Live

Runs speech and visual AI models locally to auto-generate YouTube chapter timestamps — free, no upload, no signup, built for YouTubers who don't want to type timestamps by hand.

FreeNo sign-upWorks offlineData stays with you

You upload a video and it uses Whisper for audio and Moment-DETR for visual analysis to detect natural chapter breaks, then outputs timestamps to paste into a YouTube description.

Pricing
Free, no signup.
Best for
YouTubers who don't want to manually type out chapter timestamps.
Watch out
The 18/19 accuracy figure comes from a single 68-minute test video, not a broad benchmark.
