About Language Detector
Detect the language of pasted text across 20+ languages using stopword and character-frequency analysis.
Language Detector identifies the language of any pasted text across more than twenty languages using a blend of stopword matching and character frequency analysis. Drop in a single word, a full paragraph or a whole document and it returns the most likely language with a confidence percentage, plus the runner up languages so you can judge ambiguous cases. It recognises Latin, Cyrillic, Greek, Arabic, Hebrew, Devanagari, Chinese, Japanese and Korean scripts, which makes it useful for sorting multilingual inboxes, checking a translation request or confirming what a customer wrote. Short inputs are handled with a clear low confidence warning instead of a guess. Detection runs offline in your browser, so the text is never uploaded, and Language Detector is completely free to use.

Frequently Asked Questions
Can Language Detector identify a language from just one or two words?
It can, but confidence drops sharply on very short input because stopword and character frequency signals need some text to work with. The tool shows the confidence percentage alongside the result, so a low number is your cue to paste more words. For phrases under about fifteen characters, treat the top match as a hint rather than a final answer.
Is Language Detector free to use?
Yes. Language Detector is completely free with unlimited use — no account, download or payment required.
Is my data uploaded to a server?
No. Language Detector runs entirely in your browser. Your inputs are never sent to our servers or stored anywhere.
Does Language Detector work on mobile?
Yes. The interface is fully responsive and works in any modern browser on Android, iPhone, tablets and desktops.
