Is Whisper transcription really free online?

Yes. The Whisper and Moonshine models run on your own device, so there is no per-minute billing, no free-tier cap, and no sign-up — transcribe as much audio as you like.

Do my recordings get uploaded anywhere?

No. Transcription happens entirely in your browser via WebGPU or WebAssembly. Your audio never leaves your device, with no processing upload. Offline use requires all model and runtime assets to be cached.

Which languages can I transcribe?

English audio runs on Moonshine for the fastest results, and 90+ other languages run on Whisper — including a Translate to English option for foreign-language recordings.

Can I transcribe without an internet connection?

Offline use depends on cached model and runtime files. Complete setup and test transcription before disconnecting.
