Mimi turns speech from your computer or microphone into live translated subtitles. Watch films, follow streams, or take lessons with subtitles floating over your screen.

• Choose system audio, microphone, or both. System audio is the default; microphone capture requires explicit selection.
• Translate audio from a selected app on macOS or Windows 11.
• Show original text, translations, or both.
• Adjust subtitle position, size, and color, or let mouse clicks pass through the window.
• Save subtitles or audio locally and export TXT / WAV when needed. Saving and recording are off by default.

Get started

For your first setup, we recommend starting with Alibaba Cloud. We’ve done more real-world testing with it. We’re still improving support for other services, so results and reliability may vary.

1. Open Settings → Speech & Translation, add a configuration, enter the requested provider credentials, and save.
2. Choose the recognition and translation languages.
3. Play something and turn on Live Subtitles under Subtitles. On macOS, allow Screen & System Audio Recording when asked.

Bring your own provider credentials. Audio is sent to your configured speech service; cloud usage charges may apply.

Try Index-Translate

Bilibili's Index-Translate currently offers a free public translation API (as of October 5, 2026). You can try it in Mimi and compare the subtitle translations with your usual service.

In Settings → Speech & Translation, open an Alibaba Cloud configuration and select OpenAI-compatible API under Text translation. Use the values from the official example:

Field	Value
Service address	https://index-translate.bilibili.com/v1
Model name	Index-Translate-35B-A3B
API Key	Leave empty; the public API currently requires no authentication.

Save, then run the connection check beside Text translation. If this address already has a saved key, remove it with Remove translation key and save again.

Index-Translate handles text translation only: keep your Alibaba Cloud speech-recognition credentials configured; recognition may still incur charges. Free API availability is subject to the upstream service.

FAQ

macOS keeps asking for recording permission even though it is enabled? Quit Mimi, then remove and re-add only its entry in System Settings → Privacy & Security → Screen & System Audio Recording. Use /Applications/mimi.app for the release app or /Applications/mimi-dev.app for development, enable it, and reopen the same app. See permission recovery.
