Question 1

Is this AI translator really free?

Accepted Answer

Yes, 100% free with no signup, no API key, no usage limits, and no watermark. The AI model (NLLB-200, ~240MB) runs entirely in your browser using WebAssembly. There are no server costs because no text is ever uploaded.

Question 2

Is my text sent to a server?

Accepted Answer

No. The NLLB-200 model runs 100% in your browser. Your text is processed locally and never leaves your device. There is no signup, no account, and no data collection. This makes it safe for translating confidential documents.

Question 3

How many languages does it support?

Accepted Answer

Over 200 languages, powered by Meta's NLLB-200 (No Language Left Behind) model. This includes all major world languages plus many low-resource languages that other translators do not support. The tool shows the top 40+ languages by default with an option to browse all supported languages.

Question 4

Does it work offline?

Accepted Answer

After the initial model download (~240MB, cached in your browser), the translator works completely offline. No internet connection is needed for translation after the first use. The model is cached in IndexedDB and persists across browser sessions.

Question 5

How accurate is the translation?

Accepted Answer

NLLB-200 is a state-of-the-art open-source translation model developed by Meta AI. It achieves competitive BLEU scores across 200+ languages. For major languages (English, Chinese, Spanish, French, etc.), quality is comparable to Google Translate. For low-resource languages, quality may vary but is often the only option available.

Question 6

Can I translate long documents?

Accepted Answer

Yes. The tool automatically splits long text into sentence-level chunks for reliable translation, then reassembles the results. There is no hard character limit, but very long texts may take more time to process since translation happens locally on your device.
