Uvinta

A translator for macOS: a translation window with styles and a grammar check, quick translation of selected text with a hotkey, a typing assistant in any app (word completion and proofreading), voice input and a simultaneous interpreter that can speak the translation.

Text is translated by a local model right on this Mac, without the internet, or by the online model that comes with an Uvinta Cloud subscription. Speech is always recognized on this Mac.

What will be installed

• “Uvinta” in the Applications folder. An older version is replaced; your settings and downloaded models are kept.
• Inside the app: speech recognition (whisper.cpp), the local model engine (llama.cpp), the Supertonic speech helper and its own Python for the MLX model — nothing else needs to be installed.

Models are downloaded separately

They are not part of the installer; each is downloaded in Settings → Models → Local LLM, and a feature that needs a missing one says so:

• Whisper for voice input and the interpreter — about 875 MB;
• a local language model, if you want to work without the cloud: Hy-MT2 1.25-bit (0.9 GB), Hy-MT2 4-bit (1.1 GB) or Gemma 4 E2B (3.3 GB, also completes words and checks style);
• Supertonic 3 to speak the interpreter’s translation — about 460 MB, with the watermark that marks the voice as AI-generated.

Requirements: a Mac with Apple Silicon (M1 or later) and macOS 14 or later; the interpreter listens to the Mac’s own sound from macOS 14.2.

The interface follows the language of macOS, in any of 18 languages; it can be changed in Settings → Appearance.
