What is speech to text?
This tool transcribes audio to text using a small AI model that runs in your browser. The audio and the model never leave your device.
The first run downloads the model (~40 MB). After that, transcription works offline. You can upload an audio file or record from your microphone.
Output is shown as text with timestamps. You can copy the text, download as .txt, or download as .srt subtitles (compatible with YouTube, VLC, and most video editors).
Everything — the audio, the model, and the result — stays on your device. There is no upload, no account, and no analytics on the audio itself.
