Files never leave your device
Generate subtitles for a video or audio file automatically: the Whisper neural network recognizes speech right in your browser, and the file is never uploaded. Review and fix the lines, then download SRT, VTT or text with timestamps — or burn the subtitles into the video.
How it works
- Choose a video or audio file — MP4, MOV, WebM, MP3, M4A, WAV and more — or drag it onto the page.
- Keep the language on Auto or pick it yourself and press “Recognize speech”. On the first run the browser downloads the model.
- Review the lines: fix the text and timing and listen to doubtful spots. Download SRT, VTT or TXT, or press “Burn into video”.
Frequently asked questions
Is my video uploaded anywhere?
No. Speech is recognized by the Whisper neural network in your browser: on the first run it downloads the model from our site once, then the browser keeps it in its cache. The video and its sound never leave your device.
How accurate is the recognition?
Clear speech without music is recognized well, especially in English, Spanish, Russian and other widely spoken languages. Noise, music, accents and overlapping voices cause mistakes — that is why you can review and fix every line before downloading.
Is it free?
Yes. All tools are free, with no sign-up and no watermarks.
Are my files uploaded to a server?
No. Everything runs in your browser, so your files never leave your device.
