How it works
- Choose a file. Your browser reads the audio track locally.
- The first time, the Whisper model downloads (40-80 MB) and is cached for next time.
- The audio is transcribed on your device in parts, so text appears as it goes.
- Copy the text or download TXT, SRT or VTT.
Speed and accuracy
| Model | One-time download | Best for |
|---|---|---|
| Fast (Whisper tiny) | about 40 MB | Clear English speech, quick drafts, older devices |
| Accurate (Whisper base) | about 80 MB | Most uses, other languages, accents |
Speed depends on your device. On a typical laptop, expect very roughly 2 to 8 times faster than real time with the Fast model and somewhat slower with Accurate; phones are slower.
Honest limits
- It does not label who is speaking.
- Music, overlapping voices, and background noise reduce accuracy.
- Names and specialist terms often need correcting.
- Lower-resource languages are less accurate than English or Spanish with small models.
Your files stay private
Most free transcription sites upload your recording to their servers. ScribeRuler runs the model inside your browser, so the audio never leaves your device. Only the model files are downloaded.
