Every word, in context

Read in the original

1000+ real books in English — timeless classics or your own files (EPUB, FB2, TXT). Read in a modern, fully customizable reader — themes, fonts, size, layout — and tap any word to translate it in context.

Ultra-detailed dictionary

Master the nuances, not just the translation — every word unpacks into 20+ details: IPA pronunciation (US & UK), CEFR level, frequency, word forms, collocations, synonym nuances, phrasal verbs, register, etymology, and learning tips, etc.

A vocabulary you never forget

Build your own collection of words, then let spaced repetition (SRS) resurface each one right before you would forget it — so it sticks for good.

Ask AI in context

Tap any sentence or word and ask the AI tutor — explain it, simplify it, check the grammar, or type your own question. Answers stream back in real time.

Write better every day

Write a short essay each day and get exam-style feedback — band scores, every mistake explained in your own language, and proof that your level is improving.
