How It Works

The AI Language Detector uses character n-gram frequency analysis to identify languages. Every language has a unique fingerprint of common letter pairs and triples. By extracting n-grams from your input and comparing them against pre-computed frequency profiles for 29 languages, the tool finds the closest statistical match.

The confidence score reflects how strongly the input matches the top language versus the runner-up. Longer texts produce more reliable results as more n-gram data is available for comparison.

Frequently Asked Questions

Language detection uses character n-gram frequency analysis. Every language has unique patterns of letter combinations (n-grams). By comparing the n-gram profile of your input text against pre-computed profiles for 29 languages, the tool identifies the closest match and provides a confidence score.
Accuracy depends on text length and quality. For text longer than 50 characters, accuracy is very high. Very short texts (under 20 characters) or texts with mixed languages may produce less reliable results. The confidence score helps you gauge reliability.
Currently, the detector identifies the primary language of the entire text. For multilingual content, the dominant language (the one with the most matching n-gram patterns) is reported. We recommend testing each language segment separately for best results.
The AI Language Detector supports 29 languages: English, Spanish, French, German, Italian, Portuguese, Dutch, Russian, Chinese, Japanese, Arabic, Hindi, Turkish, Swedish, Polish, Danish, Finnish, Norwegian, Czech, Greek, Korean, Thai, Vietnamese, Indonesian, Malay, Romanian, Hungarian, Ukrainian, and Hebrew. More languages are added regularly.
Short texts (under 20 characters) provide fewer n-gram samples for comparison, making it harder to distinguish between similar languages. For best accuracy, use text that is at least 50 characters long. The confidence score will automatically reflect lower reliability for short inputs.
