How to use the Language Detector
- Paste a complete sentence or paragraph into Text to detect, with at least 20 characters after spaces at the ends are removed.
- Press Detect language to compare the text with the local language profiles.
- Read the language name, three-letter language code, and up to three ranked guesses in Alternatives.
- Try a longer passage in one language if the guess looks wrong. The rounded distance values are relative match scores, not confidence percentages.

Frequently asked questions
Answers about text length, supported languages, local detection, ranked alternatives, privacy, and guesses to double-check.
When should I use the Language Detector?
Use it when you want a quick browser-side AI helper for this task: Check the likely language of a support note, comment, or short review before routing it. Compare alternatives when Spanish, Portuguese, Italian, or French text looks similar. It is best for drafts, checks, and learning, not final expert decisions.
What do the main Language Detector inputs mean?
Paste one natural sentence or short paragraph, such as a support note, product review, or copied message. For example, a 5 to 50 word note is usually stronger than 1 or 2 loose words. Avoid single words, names, addresses, URLs, and tracking codes because they can look like many languages.
How should I read the Language Detector result?
Read the top language as the best guess and alternatives as nearby matches. If Spanish is high but Portuguese also appears, check the full sentence before translating or tagging it.
What should I double-check before trusting the Language Detector?
Check short text, mixed-language text, romanized words, names, addresses, URLs, and technical strings manually. A language detector is a clue, not proof of the writer, country, or location.
Does this AI tool upload my input to Access Free Tools?
Language detection compares your pasted text with franc-min language profiles in this browser tab. It does not upload the text to a language-detection service. See the Privacy Policy for separate site analytics and session-replay handling.
Why can the first run take longer than normal?
The browser loads the small franc-min package when you press Detect language. This detector does not download an AI model or OCR files. Use at least 20 characters after trimming outer spaces, and try a longer sample in one language if a guess looks wrong.
Can I rely on the AI result as a final answer?
No. Treat it as a helpful estimate or draft. AI and text-analysis tools can misunderstand short inputs, blurry images, unusual wording, mixed languages, or topics outside their training data.
