What the AI Language Detector does
Paste in any snippet of text and this tool identifies which language it is written in, choosing from more than 100 possibilities. It is powered by a fine-tuned XLM-RoBERTa model that runs inside your browser through WebAssembly, so the text you check is analysed on your own device and never uploaded to a server.
It is useful when you receive a message or document in an unfamiliar language, when you are sorting or routing multilingual content, when preparing text for translation, or when you simply want to confirm what language a passage is in before acting on it.
How language detection works
XLM-RoBERTa is a multilingual transformer trained on text from 100 languages at once, so it has learned the characteristic letter patterns, common words and character sequences that distinguish one language from another. When you submit text, it weighs these signals and returns the most likely language, usually with a confidence score.
Because it relies on patterns rather than a dictionary lookup, it handles mixed scripts and informal writing well, but very short inputs give it less to work with. A single word or a string of names can be ambiguous, while a full sentence or two is almost always identified confidently.
How to use it and getting good results
Type or paste your text and run the detection; the model downloads once on first use and is cached afterwards for instant results. For the most reliable answer, give it a complete sentence or more rather than an isolated word. Keep in mind that languages which share an alphabet and borrow vocabulary from each other are the trickiest to tell apart, so a longer sample always helps the model decide.
