Frequently asked questions

Stenovo is an AI transcription service that turns audio and video into an accurate, searchable transcript plus a clear summary with the key points. Upload a file in the app to get started. An optional browser extension can also capture the audio playing in a tab.

98% accurate on clear audio, which puts it on par with professional human transcription. The 98% comes from the Whisper large-v3 family we build on, at roughly 2% word error rate on clean English speech; controlled studies measure professional human transcribers at about 5% on conversational audio, not the 99% the industry usually advertises. See the Whisper benchmarks and the human-parity study.

Minutes. Your file is processed in the background, and the transcript and summary appear as soon as it is done. Pro files go through with the highest priority.

No. Stenovo runs in your browser: sign in, upload a file, read the result. The browser extension is optional: it is there for when you want to capture audio playing in a tab instead of uploading a file.

Audio and video: MP3, MP4, M4A, MOV, AAC, WAV, OGG, OPUS, MPEG, MPG, WMA and WMV.

Pro supports files up to 300 minutes or 2 GB each. If your file exceeds that limit, you can request a higher one. We review every request and reply personally by email.

57 languages, on every plan. You can pick the language yourself or let Stenovo detect it automatically. That is fewer than the ~98 languages the underlying Whisper models were trained on: we list only the ones that transcribe at usable error rates, because the long tail comes back as text you would have to rewrite anyway. See the per-language WER breakdown from OpenAI.

Yes. Download it as PDF, TXT or SRT subtitles, with or without timestamps, or copy the transcript or the summary straight to your clipboard.

In your account, where they stay searchable. As long as you sign in with the same Google account, everything you have transcribed is waiting for you.

Your files are transmitted over encrypted connections and handled using access controls, so only you can see them. We never sell your data or use your files, transcripts, or summaries for advertising. See our Privacy Policy for the details.

No. The extension only captures the audio of the specific tab you start it on, and only after you start it. It never captures your microphone, your screen or any other tab. Separately, the app has a Record button that does use your microphone — but only while you have a recording running, and only after your browser asks your permission.

Yes, and you do not need to ask us. Delete any single transcript from your library, or use Delete account in the user menu to remove your account and everything in it. If you have an active Pro subscription, cancel it in the billing portal first.
