BookShelf — Read & Learn Words

BookShelf turns reading into the most natural way to learn a language. Import your own EPUB books, read in a clean, distraction-free reader, and tap any word you don't know — the translation appears instantly, right where you're reading.

But a dictionary only tells you what a word means. BookShelf goes further: an AI grammar assistant explains how the word actually works in the sentence you're reading — tense, form, nuance, and why it's used that way. It's the difference between "look" meaning "воля" out of context and understanding "people will call" as a real future tense.

Every word you tap can be saved to your personal vocabulary, synced across your devices, and reviewed later. When you're ready to practice, export your words to Anki, Quizlet, or CSV and keep learning wherever you like.
