The same word card opens from a YouTube subtitle, a Netflix subtitle, text on any web page and a word inside a PDF — and everything you save lands in a single deck that comes back to you on a schedule you never have to configure. arbitrage /aʁ.bi.tʁaʒ/ noun · masculine uncommon **in this sentence** refereeing — the officiating of the match **also means** arbitration (law) · arbitrage (finance) **from Tatoeba** L’arbitrage a été contesté. — The refereeing was disputed. Tout le monde parlait de l’arbitrage après le match. Everyone was talking about the refereeing after the match. `P` Previous `R` Repeat `N` Next `A` Auto-pause `Y` Say it back The subtitle box and word card, as they actually appear. *dotted underline* = statistically uncommon word *faded* = a word you marked known Watch ## Video, subtitles and everything that happens inside a player. YouTube and Netflix have dedicated support; any other site works if it exposes a readable caption track. Captions are rebuilt into whole sentences before anything is translated, so replay and repeat land on real boundaries rather than mid-clause. [ ### YouTube dual subtitles Original and translation together, rebuilt into sentences, every word clickable.

Read more](https://noalingua.com/features/auto-pause/)[ ### Video difficulty Graded against your deck, not against a fixed level — plus the new words, ranked. Read more](https://noalingua.com/features/video-difficulty/) Read ## Web pages, PDFs, your own documents and the word card itself. The same word card opens from a subtitle, a paragraph on any site, and a word inside a PDF. It gives the meaning that word has in that sentence — not the first entry in a dictionary — with the grammatical form you clicked, its pronunciation and real examples. [ ### The word card Contextual meaning, lemma resolution, conjugation tables, IPA and real examples.

Read more](https://noalingua.com/features/ai-explanations/) Speak ## Shadowing and pronunciation, with honest limits on the scoring. The part most tools leave out, because it is the part that needs a microphone. Whole-video shadowing runs the loop for you; Say It Back scores what speech recognition heard against the line. No audio is ever recorded or uploaded — only the score and the missed words are kept. [ ### Shadowing & Say It Back Whole-video shadowing, single-sentence drilling, and scored pronunciation feedback.

Cards come back before you forget them, carrying the sentence and the source they came from, and every export format is free on every plan — including the free one. [ ### Vocabulary review Two schedules, one deck, source context on every card, and export that is always free.

Read more](https://noalingua.com/features/guided-course/) Every feature page has a limits block Not a disclaimer at the bottom — a real section, because a page that only lists what something does is not a description, it is an advertisement. The complete list lives at [what NoaLingua cannot do](https://noalingua.com/limits/), and 30 practice formats are broken down on [the games page](https://noalingua.com/features/practice-games/). ## Try NoaLingua on the next video you were going to watch anyway.
