Translate as you read, learn as you translate. Smart Translation is both a translation tool and a learning tool. Full-page translation lets you read English at any difficulty — but more importantly, it highlights the words you want to learn, right on every page you read, from three sources you switch on as needed: • CEFR-level words — automatically marks words above your level that are worth learning (passive) • Your saved words — anything in your wordbook gets marked wherever it appears again • Word packs — load NGSL / Business / TOEIC and more; their words light up as you read Tap any marked word for its in-context meaning, examples and audio, and save it in one click. With the wordbook's spaced review and Anki export, the words you keep meeting in real reading actually stick. The whole loop lives inside normal reading — no extra effort. • Full-page bilingual translation — understand any English page • Bilingual video subtitles — players that render captions as page text (e.g. YouTube) are translated inline • Floating dock, difficulty offset, multilingual UI Grammar marks coming soon — from words to sentences.
