Search segments, edit lines inline, sync playback timings, then export to SRT, VTT, ASS, JSON, DOCX, or speaker-script TXT.

URL diarization FAQs

How many speakers can the diarizer handle?+

Two to ten reliably in typical interview / podcast audio. Crowd scenes degrade like any system, but two- and three-person setups are essentially perfect.

Can I rename Speaker A and Speaker B?+

Yes. Rename any speaker once and the change propagates across every cue and every export format.

Are speaker IDs preserved in every export?+

Yes. SRT keeps them in [brackets], VTT uses <v Speaker A>, ASS uses the Name field, JSON has a speaker key per segment, TXT and DOCX use Speaker N: prefixes.

What URL hosts work for diarization?+

All the common ones: YouTube, Vimeo, Drive, Dropbox, Loom, S3, and direct .mp4 / HLS links.
