Score: 6.8/10 (Innovation: 6, Technical: 7, Documentation: 7, Utility: 7)

A polyfill for the browser's experimental LanguageDetector Web API, enabling consistent language detection across all major browsers using Google's CLD3 neural network model via WebAssembly. It is interesting because it fills a compatibility gap for a modern browser API with on-device, privacy-preserving processing and a well-designed drop-in interface.

Target audience: frontend devs, web developers
