## Overview
Nola Translator turns speech into real-time captions and translations. Run speech recognition and translation locally, use cloud services, or combine the two.
## Features
- **Local models:** Run recognition models such as Qwen3-ASR and SenseVoiceSmall, and translation models such as HY-MT2 locally. The app can also search for and install other models from Hugging Face.
- **Cloud models:** Use speech recognition from Aliyun, MiniMax, and other providers; connect translation models through LLM protocols such as OpenAI-compatible APIs, Anthropic, or Ollama; or use the free MyMemory translation service.
- **GPU acceleration:** Detects available compute devices and lets you configure separate devices for recognition and translation.
- **Browser extension:** Includes a browser extension for Chrome and Edge that displays bilingual captions on video pages. You can also configure desktop system audio as an input source.
- **Real-time caption overlay:** Supports system output, a selected audio device, or a microphone. Captions appear in a separate overlay, where you can adjust its position, font size, colors, opacity, and original/translated text layout.
- **Flexible configuration:** Install models as needed and choose recognition and translation methods, language directions, compute devices, and caption styles. API credentials are securely stored by the app.
- **History and export:** Save caption history and export it as TXT, SRT, or WebVTT. Audio recording can be enabled optionally.

## Language Support
> [!TIP]
> The languages available for recognition and translation depend on the selected model's capabilities. The tables below show the capabilities of the recommended models included in the app. If you have a model to recommend, submit it as an issue; we will evaluate it for possible inclusion. For first-time users, we recommend **SenseVoiceSmall** for recognition and **HY-MT2 1.8B** for translation.
