How it works

  1. Drop your file

    Interview, podcast, voice memo, lecture, video — audio or video both work.

  2. We listen

    Speech recognition runs on your device and picks up the language automatically.

  3. Edit and export

    Fix any word, then copy the text or download TXT, SRT or VTT.

How the transcriber works

We use Whisper, the open speech recognition model known for handling accents, background noise and technical words well. It runs inside your browser using your device’s graphics chip when available — so nothing is uploaded and there’s no queue.

The first time, your browser downloads the model once (about 80 MB for Fast, 250 MB for Accurate). After that it’s stored on your device and starts instantly.

Every word gets a timestamp, so subtitle files line up with the audio. Click a timestamp to jump there and check it.

Questions

Is the transcriber free? Is there a minutes limit?
It’s completely free with no minute limit. The only limit is what your device can handle — most computers do hours of audio.
Which languages are supported?
Around 99, including English, Spanish, French, German, Dutch, Portuguese, Italian, Japanese, Korean, Chinese, Hindi and Arabic. Leave it on “Detect automatically” or pick one.
How accurate is it?
Clear speech is usually transcribed very accurately. Choose “Accurate” for difficult audio, accents or less common languages. You can fix anything in the editor before exporting.
What are SRT and VTT?
Subtitle files with timestamps. Upload SRT to YouTube, Facebook or editing apps like Premiere and DaVinci Resolve. VTT is the web standard used by players and LinkedIn.
Are my recordings private?
Yes. Your file is processed on your device and never uploaded. Only the speech model is downloaded, once.
Why is it slow on my phone?
Speech recognition is heavy work. Phones can do it, but slower than a computer. Pick “Fast” for quicker results.
