Automatically detect the language of your text. Supports multiple languages including English, Spanish, French, German, and more.
A language detector is a tool that analyzes text patterns, character sets, and common word frequencies to identify which language a piece of text is written in. It provides confidence scores for each potential match, allowing you to determine the primary language even when text contains words from multiple languages. Our free language detector supports 12+ languages including English, Spanish, French, German, Italian, Portuguese, Dutch, Russian, Chinese, Japanese, Korean, and Arabic. For a detailed guide, check out our article on how to detect the language of any text.
Language detection is the first step in many multilingual workflows. Once you know the language, you can apply the right grammar rules, generate appropriate meta tags for SEO, or route content to the correct translation pipeline. It is also essential for content moderation, customer support routing, and data categorization at scale.
Automatic language detection is essential for global businesses, content platforms, and multilingual applications. For SEO, correctly identifying content language ensures you set the right hreflang tags and serve the right content to the right audience. Misidentified language leads to poor indexing and wasted crawl budget. For businesses, language detection enables automatic routing of customer support tickets, content categorization, and localization workflows without manual identification. Check your detected content with our Readability Score tool to ensure it meets audience expectations, and use the Character Counter for length verification.

Yes, our detector shows confidence scores for multiple languages when your text contains elements from different languages. This is useful for identifying multilingual content or code-switching between languages.
For best results, provide at least 20-50 words. Single words or very short phrases may be detected incorrectly due to similarities between languages. Longer passages provide more data points for accurate identification.
Low confidence can occur with: very short text, technical jargon, proper nouns, mixed-language content, or languages not in our detection set. Numbers, URLs, and code snippets may also reduce confidence as they're language-neutral.
