Language coverage
NoaLingua supported languages—and what “supported” really means
A language can appear in the selector while a particular offline translation pair, grammar pack or speech model is unavailable. This page separates those layers.
No account. No analytics. The free plan lets you try every feature.
Quick answer
NoaLingua supported languages—and what “supported” really means
The current manual documents English, Spanish, French, German, Italian, Portuguese, Russian, Dutch, Polish, Swedish, Japanese, Chinese, Korean, Arabic, Turkish, Serbian, Croatian, Czech, Greek, Hindi, Vietnamese, Thai, Ukrainian, Romanian, Hungarian, Finnish, Danish and Norwegian in the learning and translation selectors.
How it works
Translation coverage
Chrome on-device translation supports only some language pairs. YouTube’s own caption translation covers many more languages and acts as a fallback on YouTube. Optional cloud translation is another explicit choice. A listed language therefore does not guarantee the same offline translation path for every pair.
How it works
Dictionary and grammar coverage
Word dictionaries, UniMorph grammar data, Wiktionary/Kaikki packs and Tatoeba examples are separate datasets. A language may have strong dictionary coverage and limited morphology, or the reverse. Download status in NoaLingua shows which pieces are actually present.
How it works
Speech and AI coverage
Say It Back depends on a Chrome speech pack or an online option the learner enables. AI explanation depends on Chrome’s on-device model, which is unavailable on many devices. Shadowing without speech scoring, saved vocabulary, games and manual review do not depend on either model.
How it works
Frequency highlighting
The manual currently documents frequency lists for English, Spanish, French, German, Italian, Portuguese and Russian. Those lists power uncommon-word highlighting; their absence does not disable subtitles, lookup or review for other languages.
Questions answered
Frequently asked questions
Does NoaLingua support Japanese and Korean?
Both appear in the documented language selectors. Exact dictionary, grammar, speech and offline-translation coverage should be checked in Downloads for the current browser and language pair.
Can NoaLingua translate Serbian or Croatian?
They appear in the documented selectors. The manual notes that Chrome local translation does not cover every pair, while YouTube-native translation covers many more languages.
Why is one feature available in Spanish but not another language?
Each feature depends on a different dataset or Chrome model. NoaLingua reports those components separately instead of treating language support as one yes/no claim.
