NoaLingua — beyond dual subs: video, web, PDF

YouTube, Netflix & web dual subtitles. Click a word: grammar, context, examples. Bilingual docs, 30 SRS games, speak & get scored.

Made by a polyglot, for those who like to learn fast, easy and with fun. ❤️ Learn languages with YouTube, Netflix, websites and PDFs — dual subtitles, click-any-word explanations, shadowing, pronunciation practice, bilingual PDFs, spaced repetition and 26+ learning games. NoaLingua turns the content you already watch and read into a complete language-learning system. Watch a video with two subtitle languages. Click a word and understand what it means in that exact sentence. See grammar, forms, pronunciation and real examples. Save it with the original sentence and video moment. Then let NoaLingua bring it back through spaced repetition, listening, writing, grammar and vocabulary games. One extension. Your videos, websites, PDFs and saved vocabulary — all connected. 🔥 WHAT YOU CAN DO WITH NOALINGUA 🎬 DUAL SUBTITLES FOR YOUTUBE, NETFLIX & MORE Watch videos with the original subtitle and translation together. NoaLingua gives you video controls made specifically for language learning: • Original + translated subtitles • Clickable words • Previous / repeat / next sentence • Auto-pause after each sentence • Automatic sentence repetition • Slow replay • A–B loops • Hide translation until you reveal it • Focus mode • Hover to pause • Adjustable subtitle size, position and appearance Instead of stopping the video, opening another tab and searching a word, everything stays inside what you are watching. 🧠 CLICK ANY WORD — GET THE WHOLE PICTURE A word is more than a translation. Click a word in a subtitle, website, PDF or bilingual reader and NoaLingua gives you everything around it: • Translation • Meaning in the current sentence • Part of speech • IPA pronunciation • Spoken pronunciation • Base form • Conjugation or declension • Full grammar tables • Multiple meanings by word type • Real example sentences with translations • Fixed expressions and phrases • Uncommon-word highlighting NoaLingua uses the sentence around the word, so you learn the meaning that actually belongs there — not just the first dictionary definition. 🗣️ SHADOWING BUILT DIRECTLY INTO THE VIDEO Turn any video into speaking practice. Full-video Shadowing automatically: 1. Plays a sentence 2. Pauses the video 3. Gives you time to repeat it 4. Continues to the next sentence You can also shadow one sentence at a time: listen → repeat → listen again. No manual pausing. No constantly dragging the timeline back. 🎙️ SAY IT BACK — ACTUALLY SPEAK THE LANGUAGE Speak the sentence yourself and let NoaLingua check what it heard. Say It Back can: • Listen after each sentence • Show recognized words in real time • Give you a percentage score • Mark the words you missed • Give you another attempt • Remember recurring problem words for later practice Videos stop being only listening material. You start producing the language too. 📜 FULL INTERACTIVE VIDEO TRANSCRIPT Open the complete video transcript beside the player. You can: • Follow the active sentence • Click any sentence to jump to that moment • Search the transcript • Read it as continuous text • Click words directly inside it • Find unfamiliar vocabulary • See recurring grammar constructions • See how difficult the video is for you • Download the transcript as .txt One video becomes something you can watch, listen to, read, search and study. 📄 TURN A YOUTUBE VIDEO INTO A BILINGUAL PDF One click can turn the full YouTube transcript into a bilingual PDF. Original sentence. Translation directly underneath. The whole video becomes something you can read, print, review or keep. Your listening material becomes reading material too. ✨ AI EXPLANATIONS FOR REAL SENTENCES When a sentence is confusing, don't start searching five different things. Open the explanation panel and choose: • Explain — what the sentence means and why it is built that way • Grammar — understand the construction being used • Idiom — find expressions that should not be translated literally • Simplify — see the same idea in easier language • Examples — get more sentences with the same word or construction NoaLingua can use the surrounding video context too, instead of treating every sentence like it appeared from nowhere. 🌐 LEARN FROM ANY WEBSITE NoaLingua isn't only for videos. While reading articles, blogs, forums or other pages you can: • Select text and translate it • Click individual words inside the translation • Translate a paragraph directly underneath the original • Highlight words you haven't encountered before • Save useful vocabulary while you read • Open selected text as a bilingual book A random article can become language-learning material in seconds. 📚 TURN PDFs INTO LANGUAGE-LEARNING MATERIAL Open a PDF and choose how you want to study it. BILINGUAL BOOK • Original and translation side by side • Paragraphs aligned • Hover a sentence to highlight its translation • Click words for meaning and grammar • See how much vocabulary you already know INTERACTIVE PDF VIEWER • Keeps the original PDF layout • Keeps images, columns and document structure • Makes the text clickable • Uses the same word-learning popup as videos and websites You can also import your own TXT, SRT, VTT, Markdown or pasted text and read it inside NoaLingua. 💾 SAVE WORDS WITH THEIR REAL CONTEXT A saved word shouldn't become another disconnected flashcard. When you save vocabulary from a video, NoaLingua can keep: • Original sentence • Sentence translation • Video title • Video URL • Exact timestamp • Grammar and definitions • Example sentences • Labels • Sentence audio So weeks or months later, you can still see where that word came from and return to the exact moment where you learned it. 🧩 26 QUESTION TYPES + 4 CHALLENGES Saved vocabulary doesn't disappear into a boring list. NoaLingua turns it into active practice across: • Meaning • Producing the word • Grammar • Listening • Sentence context • Rebuilding sentences • Writing what you hear • Mixed review sessions • Dedicated challenge modes Choose the games you like, mix everything together, practice only grammar, or simply open Learn and review what's due. 🧠 SPACED REPETITION CONNECTED TO REAL CONTENT NoaLingua remembers what you're learning and brings vocabulary back when it's time to review it. But it tracks more than whether you got a flashcard right. See: • How many times you encountered a word • How many times you clicked it • How many times you reviewed it • Which videos you encountered it in • Different forms in which you met it • Words that keep giving you trouble That means the words you meet naturally while watching and reading become part of the same learning system as your active review. 🎓 GUIDED LEARNING + YOUR OWN CONTENT Want structure? Use a guided A1 → C1 vocabulary path and frequency-based courses. Prefer immersion? Learn entirely from your own videos, websites and PDFs. NoaLingua can even surface useful words to learn next based on the content you actually watch. 📦 EXPORT TO ANKI & KEEP YOUR MATERIAL Your vocabulary isn't trapped inside NoaLingua. Export your saved material as: • Anki-compatible CSV • Full JSON • Spreadsheet CSV • Anki cards with pictures and real sentence audio Use NoaLingua's review system, build your own, or combine both. 🔒 LOCAL-FIRST LANGUAGE LEARNING NoaLingua is designed to do as much work as possible directly on your device.
