Speech to text, on your device

Record or open an audio or video file and get an editable transcript. Your audio never leaves this browser.

  • Transcribed on your device
  • 99 languages
  • Word, PDF, SRT, VTT
  • Free to use

Ready. Record, or open a file.

The microphone is asked for only when you press Record.

A first draft of your opening words appears about 15 seconds in; after that the text follows about 30 seconds behind your voice, transcribed on this device. Ticking it makes Record also download the speech model first (about 71 MB, once). The recording never depends on the draft.

This is what this browser says it can read. Up to 2 GB per file on a computer; a phone is best with shorter recordings.

How it works

Questions

Is my audio uploaded?

No. The speech model runs in your browser, so the recording is read and transcribed on your device. You can check: open your browser’s network panel and watch while you transcribe.

What does an account add?

A library of transcripts you choose to save, and read-only share links that expire. Saving sends the text, times and labels; the audio still never leaves your device. You can transcribe without an account.

Does it work on my phone?

Yes, on iPhone and Android, in Safari or Chrome. A phone is slower than a computer and can run out of memory on a long recording, so use it for shorter ones.

Which languages, and how accurate is it?

Ninety-nine languages, worked out from the first 30 seconds; you can change it if the guess is wrong. English is strongest. The larger model is better outside English. It transcribes and never translates.

How long can a recording be?

Up to 2 GB on a computer. For a long file, transcribe the first five minutes to check the result, then run the whole recording.

Is it free?

Transcribing on your device is free. We are testing a Pro plan for cloud backup of recordings and server transcription; it is not open yet and nothing is charged.

Who this page is for, and what it will not do

The page was built for people with an obligation to whoever is on the tape. Think of a journalist with a source, a lawyer with a client, a clinician with a patient, an HR investigator with a complainant. What they share is a reason not to send a recording anywhere.

That is why the model is downloaded to your device and the audio is not uploaded to us. A recording is read, transcribed and corrected on the machine in front of you, and you decide what is saved.

Pick the job that matches yours

What it will not do

It will not translate. It will not tell speakers apart, so every speaker label is one you type. It will not hand you a certified or verbatim record, because the result is an automatic draft that you check against the recording.

It will not keep anything you did not ask it to keep. Reload the page and an unsaved transcript is gone, which is the cost of never holding your words on a server by default.

A good first session

Open a short recording you know well, press Transcribe and read the draft against the sound. In a few minutes that shows how your language, your microphone and your device behave, before you give it an hour of tape.

Check the language printed with the transcript, since a wrong guess looks like a normal transcript. Then export in the form your next step needs: subtitles for a video, a numbered PDF for citing, Word for editing.

The work is done by a speech model running inside your browser. The guide explains each step in order, from pressing Record to exporting a numbered PDF.
