AirTranslate captures audio playing on your Mac, turns it into a live transcript, translates it in real time, and can show the result as a floating caption overlay. It is designed for meetings, lectures, videos, interviews, and streams where routing audio through a microphone is awkward or lossy.

For a user-facing overview, setup guide, and download path, visit the AirTranslate Guide Site.

The default workflow uses Apple frameworks. GPT Realtime and Gemini Live Translate are optional API-backed modes and can be enabled from the app only after you provide the matching API key.

• System-audio first:** capture Mac playback audio directly with ScreenCaptureKit.
• Readable live workspace:** source and translated text stay side by side.
• Floating captions:** keep subtitles above other apps while you watch or listen.
• Apple by default:** Apple Speech and Apple Translation remain the baseline path.
• Optional API modes:** OpenAI Realtime Translation and Gemini Live Translate can be enabled only when needed.
• Keychain storage:** OpenAI and Gemini API keys are entered by the user and stored in macOS Keychain.
• Plain text history:** saved transcripts remain normal `.txt` files in Application Support.
