SubtitleGen
SubtitleGen turns uploaded audio and video into timed subtitles you can export for YouTube and other platforms. Upload a file, let it transcribe speech, then review or tweak captions in an online editor before downloading SRT, VTT, ASS, or TXT files.
Where a full video editor buries subtitles inside a timeline, SubtitleGen keeps the workflow narrow: transcription, caption editing, and translation in one place. Paid plans bundle AI translation at no extra charge, which matters if you publish the same clip in multiple languages without hiring a separate localization step.
The free tier gives you 30 credits and a 30-minute per-file cap, so you can test accuracy on a short clip before upgrading. Content creators, educators, and marketing teams use it when they need readable captions fast without installing desktop software.
