Frequently asked questions
Is my video or audio uploaded?
No. Speech recognition and every edit run in your browser on your own device. Nothing is sent to a server.
Why does it download something the first time?
The speech model (41 to 250 MB, depending on the quality you pick) is downloaded once and kept by your browser, so next time it starts immediately. Your files are never sent anywhere.
Which languages are supported?
Around 99 languages, including English, Spanish, Hindi, French, German, Portuguese, Japanese, Chinese and Arabic. The language is detected automatically, or you can choose it. You can also translate the speech into English captions.
What is an SRT file?
A simple text file with numbered subtitle lines and their start and end times. Almost every video player and editor supports it.
