How the language detector works
This tool uses a fast heuristic algorithm that detects scripts (Chinese, Arabic, Russian, etc.) and common word patterns (English, Spanish, French, German) — it works instantly with no downloads. An AI model (XLM-RoBERTa) can be loaded on demand for even more accurate detection across 100+ languages. Everything runs entirely in your browser.
