oqou turns anything you read into a language lesson, and now it tells you what to read next. Textbooks drill you on words you'll never use. oqou flips it: read the books, articles and stories YOU actually want to read, and pick up the language as you go. That is comprehensible input, the most natural way to build vocabulary that lasts. YOUR PLAN, IN THREE QUESTIONS Answer three questions and oqou lays out a day by day path: which story to read, when to review, which grammar point comes next. Every day is sized to the time you said you have, your days off are already in it, and if you miss a week one tap slides everything forward. Your first plan is free. THE WORDS THAT ACTUALLY COME UP Every language carries a graded list of its 2,500 most common words, ordered by how often they really appear and banded A1 to B2, each with its part of speech and a translation. One tap sends any of them to your review queue. The first 500 are free. GRAMMAR, ONE POINT AT A TIME 36 worksheets per language, A1 to C2, each drilling a single grammar point with the rule explained the moment you answer. BRING YOUR OWN CONTENT Import almost anything and start reading in seconds: • Books and documents: EPUB, PDF, DOCX, TXT • Web articles: paste a link for a clean, readable view • Anything else: paste text, or share straight from Safari, Books, or any app FIND YOUR LEVEL, THEN READ AT IT Take the quick level check in onboarding, or the full test in Settings, and oqou places you on the CEFR scale from A1 to C2, then fills your library with leveled stories that fit. TAP ANY WORD TO UNDERSTAND IT INSTANTLY • Instant translation into your language, right on your device • The correct article for every noun the moment you tap it: der/die/das, le/la, el/la, il/la, o/a • Explain in Context: an AI note on what the word means here, its tone, and how to say it naturally HEAR IT SPOKEN, AND REMEMBER IT Your device's own voice reads any page aloud from the moment you install; ten natural voices are an optional download that then works offline. Save any word with a tap, and spaced repetition brings it back right before you'd forget it. PRIVATE BY DESIGN The core reading experience runs entirely on your device.
