Live Trans
Real-time translation for any system audio, with live subtitles and voice.
About
Live Trans turns your computer into a real-time interpreter for anything you hear.
Play a foreign-language YouTube video, online course, podcast, or meeting — flip one switch and instantly read live subtitles and hear the translation in your own language, side by side with the original.
Why it's different
⚡ Real-time — translation streams as people speak, powered by Google's Gemini 3.5 Live Translate.
🎧 Any system audio — not just one app. YouTube, Zoom, Spotify, your browser — anything playing on your machine.
🗣️ Voice + subtitles — hear the translated voice and read a two-column live transcript (original + translation).
🔒 No echo loop — the audio capture excludes the app's own output, so the model never repeats itself.
💰 Live cost meter — watch token usage and spend in real time. Bring your own Gemini API key; it's encrypted and never leaves your machine.
🖥️ macOS & Windows — universal macOS build (Apple Silicon + Intel) and a native Windows build.
Free and open source under a noncommercial license. Download the latest release, paste your Gemini API key, pick a target language, and start translating in seconds.
