Check the description and scrubber for chapter titles—they are free and often accurate.
AI sections when chapters are absent
Podcasts and older uploads benefit from grouped caption text with timestamps.
Share structured links
Send colleagues to exact segments with timecoded URLs from verified timestamps.
