Transcribe files
Transcribe audio and video, on your own machine
Drop in an audio or video file, or a whole folder, and get a transcript back, plus SRT and VTT subtitles if you want them. It runs locally with Whisper, so nothing is uploaded and there is no per-minute meter.

File transcription FAQ
Is transcription done locally or in the cloud?
Locally. SnailText transcribes your audio and video files on your own machine with the Whisper speech model. Nothing is uploaded to a server, and there is no per-minute meter. Online transcription tools upload your file, which SnailText does not do.
What audio and video formats can SnailText transcribe?
Audio formats like MP3, WAV, M4A, AAC, OGG, Opus, and FLAC work immediately. Video formats (MP4, MOV, MKV, WebM) and a few extra audio formats use a one-time codec pack the app downloads for you. Pick any format page below for the specifics.
Can SnailText make SRT or VTT subtitles?
Yes. Choose SRT or VTT as the output before you run a transcription and SnailText writes a subtitle file with phrase-level timestamps, ready to drop onto a video. You can also export plain text, Markdown, or JSON.
How much does file transcription cost?
The free tier transcribes locally with the compact Whisper models, no account and no per-minute charge. Pro adds larger, more accurate models and an optional on-device AI cleanup pass, $7.49/mo or $89/yr for up to 3 devices.
