My Translator is an open-source desktop app published on GitHub that translates speech in real time on macOS and Windows, showing a clean translation overlay with no intermediary server. The project has gathered around 1,300 GitHub stars and is actively developed in 2026.
Built with Tauri and Rust, My Translator captures system audio or microphone input, transcribes it and displays translations in a minimal always-on-top overlay — designed for video calls, meetings and media. It offers four engines: Soniox for low-latency speech translation across 70+ source languages, OpenAI Realtime for text-plus-voice translation, Qwen LiveTranslate Flash on its free preview tier, and a fully local MLX mode (Whisper plus Gemma) on Apple Silicon that works offline. Two-way mode translates both sides of a bilingual conversation automatically, TTS narration can read translations aloud through Edge, Google or ElevenLabs voices, and custom term lists keep names and domain vocabulary consistent. Privacy is the design centre: audio flows directly from your machine to the API you configured, keys stay local, and there is no account, telemetry or relay.
My Translator is free and open source under the MIT license. Cloud engines bill to your own API accounts (Soniox runs about $0.12/hour; the Qwen engine and local mode are free).
Remote workers, multilingual teams and anyone in cross-language calls who wants live spoken translation without sending audio through a third-party service.
