This extension works best with Chrome's built-in AI APIs (window.ai). For the default provider, ensure you are using Chrome 131+ and have enabled the necessary flags for "Prompt API for Gemini Nano" and "Language Detection API". Alternatively, configure a different AI provider (Gemini, OpenAI, Groq, Ollama, etc.) in the extension settings.
Type your text in any input field, then add the translation command:
Hello, how are you? !!vi
→ Xin chào, bạn khỏe không?
Tôi đang học tiếng Anh !!en
→ I am learning English
