Create timed subtitles, then make them your own.
Generate a subtitle draft from speech in a video or audio recording. Review the words and display times in the cue editor, then download an SRT or VTT file for your editor, web player or publishing platform.
How to generate subtitles
- Upload the final edit of a video your browser can decode. Free local mode supports up to 200 MB and 20 minutes per file.
- Set Speech language and choose Start transcription. Local Whisper runs on your device after the model download.
- Check every cue’s text, Start and End fields. Select SRT or VTT in Export format, export the file and test it alongside your video.
Subtitle file or captions burned into the video?
This tool exports a separate text subtitle file. It does not render a new video with permanent captions. To burn in subtitles, import the reviewed SRT or VTT into a video editor and render the finished video there.
Review more than the words
Check the first cue, pauses, speaker changes and the ending. Fix overlapping timings and spelling mistakes. Add meaningful sounds or speaker labels when needed for accessible captions. Automatic recognition provides a draft; it does not guarantee complete accessibility captions or frame-perfect timing.
Already have captions? Use the subtitle converter to change formats without running recognition again.
