Language Detector
Paste any text and instantly detect its language with confidence scores. Uses Chrome's built-in Language Detector API. Runs on your device — nothing is sent anywhere.
Smart Analysis Mode: The tool will detect languages using character pattern analysis (CJK, Arabic, Cyrillic, Latin scripts) and common word frequency matching.
How This AI Tool Works
This tool uses Chrome's built-in Language Detector API to identify the language of your text with confidence scores. It can distinguish between dozens of languages and show you the top candidates ranked by probability.
If Chrome AI is not available, the tool falls back to heuristic detection using Unicode character ranges (CJK, Arabic, Cyrillic, Devanagari) and common word frequency patterns for Latin-script languages.
Detection Methods
- AI Mode — Chrome's Language Detector API provides precise identification with confidence scores for multiple candidate languages
- Script Analysis — Identifies Japanese (Hiragana/Katakana), Korean (Hangul), Chinese (CJK), Arabic, Russian (Cyrillic), Hindi (Devanagari)
- Word Patterns — Matches common function words (articles, prepositions) for Spanish, French, German, Italian, Portuguese
- Confidence Scoring — Shows probability for each detected language candidate
Privacy-First Detection
Your text is never sent to any server. In AI mode, Chrome runs the language model locally. In fallback mode, all analysis happens in JavaScript right in your browser. Ideal for identifying languages in confidential documents.
