How this free subtitle generator works

  3. Download SRT, VTT, or TXT — or import into Wisprs to edit timing and speakers.

SRT vs VTT vs TXT

SRT works in YouTube, Premiere, and CapCut. VTT is the web/HTML5 caption standard. TXT gives you timestamped plain text. For long-form video, speaker labels, and reusable captions, use meeting transcription software and podcast transcription workflows.
