Frequently Asked Questions

For most languages, 3–5 words give reliable detection. Accuracy improves with longer text. Single words can sometimes be ambiguous between related languages. Sentences of 10+ words give much better accuracy.
The tool detects the dominant language in a text. For mixed text, it returns the language with the highest statistical probability. Per-sentence mixed-language detection needs a much larger model.
Closely related languages like Spanish and Portuguese or Norwegian and Danish share many character patterns. More text improves disambiguation. Lower confidence usually means several candidates are close.
Google uses large server-side neural models and sends your text to its servers. This tool runs locally in your browser with no API call. For many everyday cases, the practical accuracy difference is small.
