Tap any word in any book and get an instant translation plus an AI grammar explanation — right where you're reading. Thousands of free classics included.
BookShelf turns reading into the most natural way to learn a language. Pick a book from thousands of free classics in 17 languages — or import your own EPUB — read in a clean, distraction-free reader, and tap any word you don't know. The translation appears instantly, right where you're reading, in your own language.
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 and synced across your devices. Then practice them with built-in flashcards — swipe to mark what you know, and BookShelf brings each word back exactly when you're about to forget it.
