Live translation questions

Is Mimi free to use for live translation?

Mimi itself is free and open source under the MIT license. Cloud speech recognition and text translation require your own credentials and may charge for usage. Supported Apple silicon Macs on macOS 26+ can use Apple local services without API keys after preparing recognition and translation language resources.

Can Mimi translate videos, streams, online classes and game audio live?

Mimi transcribes and translates the audio being played, showing original, translated or bilingual subtitles in a floating overlay. The video does not need existing subtitles. Mimi translates audio rather than text in images; language support and results depend on the chosen service and audio quality.

How do I translate system audio live on Windows or Mac?

Install the Windows or macOS version, configure a service, choose source and target languages, then start subtitles. System audio is selected by default, so you do not need to point a microphone at your speakers. On desktop, you can explicitly select a microphone or both sources, with separate source labels.

Can I use live subtitle translation on Linux or Ubuntu?

A Linux x86_64 preview is available as AppImage and DEB, with Ubuntu 22.04+ as the baseline. System audio capture requires PulseAudio or pipewire-pulse. X11 is recommended; floating overlays and shortcuts on Wayland depend on the desktop environment.

How do I get live translated subtitles on Android?

Install the APK on Android 10+, configure a service, allow the overlay and grant playback-capture consent, then start subtitles. Protected audio and apps that block capture cannot be transcribed. Physical-device and all-provider validation remain incomplete.

Choose your subtitle service.

No Mimi account needed. Cloud recognition receives audio, and remote text translation receives recognized text. Apple Speech and Apple Translation process locally on your Mac.

Keys stay on your device. Subtitle saving and recording are off by default. Turn them on to save and export.
