Browser AI Extension - Showcase of Chrome's Built-in AI APIs

[Ezequiel Cicala]

Hi Chromium Extensions team,

I'm sharing Browser AI, an open-source Chrome extension that demonstrates the practical use of Chrome's built-in AI APIs (Translator API and Language Detector API for now).

Project Overview:
- Built with TypeScript and Manifest V3
- Uses Chrome's Translator API for text translation
- Uses Language Detector API for automatic language detection
- Privacy-focused: processes text locally with no external API calls
- Simple UI with side panel and context menu integration

Technical Details:
- Requires Chrome 138+ for built-in AI APIs
- Works offline once models are downloaded
- No API costs or rate limits

This extension serves as a real-world example of implementing Chrome's emerging AI capabilities, following web standards for integrated AI.

- GitHub Repository: https://github.com/LuxDie/browser-ai
- Documentation: https://github.com/LuxDie/browser-ai/tree/main/docs

I'm looking for feedback on the implementation and welcome contributions from the community. This could potentially serve as a reference implementation for other developers exploring Chrome's AI APIs.

Best regards,
