Frequently Asked Questions
How does the AI language detector work?▼
It uses a fine-tuned XLM-RoBERTa model running in your browser via WebAssembly. XLM-RoBERTa is a multilingual transformer trained on 100 languages. The model analyzes character n-grams and word patterns to classify which language the text belongs to.
How many languages can it detect?▼
The underlying model supports over 100 languages, covering major world languages as well as many regional and minority languages. It works best with at least 20–30 characters of text.
Is my text sent to any server?▼
No. The model runs entirely in your browser using WebAssembly. Your text never leaves your device, making this tool completely private and suitable for sensitive documents.
Why does it take time on the first run?▼
The XLM-RoBERTa model (~300 MB) is downloaded once and then cached by your browser. After the initial download, subsequent uses are nearly instant — usually under a second.
