How to transcribe audio to text
- Drop an audio or video file onto the box: a voice memo, interview, lecture, meeting recording, podcast or video.
- Choose the accuracy. Balanced suits most recordings; Fast is quicker on older phones; Best handles accents, noise and other languages better. The first time, the model downloads once (the size is shown before you start).
- Pick the spoken language or leave it on automatic detection. To get English text from another language, choose Translate to English.
- Press Transcribe. Text appears section by section; click any line to hear that part.
- Download the transcript as plain text, or as SRT or VTT subtitles for YouTube, Premiere, DaVinci Resolve or CapCut.
Private transcription with Whisper
Whisper is the open speech recognition model released by OpenAI, trained on hundreds of thousands of hours of speech in nearly 100 languages. This page runs it inside your browser with WebAssembly, or with your graphics card through WebGPU where available, so the recording never leaves your device. That makes it suitable for confidential interviews, medical and legal notes, research data, therapy sessions and internal meetings, with no per-minute fees, no account and no upload limits.
Speed depends on your device: a modern laptop transcribes faster than real time with the Fast and Balanced models, while phones are slower. Clear audio with one person speaking at a time gives the best results. Whisper adds punctuation and capitals automatically, but it does not label different speakers, and it can mishear names, jargon and numbers, so proofread important transcripts. Keep the tab open while it works.
Is my audio uploaded?
No. Only the Whisper model is downloaded (once, then cached). Your file is decoded and transcribed on your device.
Which languages are supported?
Whisper understands about 100 languages. English, Spanish, French, German, Italian, Portuguese, Dutch and Japanese work best; choose the Best model for other languages.
Can it make subtitles?
Yes. Download SRT or VTT files with timings split into readable two-line captions, then fine-tune them in a subtitle editor.
How long can the recording be?
There is no fixed limit; long recordings are processed in two-minute sections. Very long files need more time and memory.
