TeaderBook
Read full descriptionHide full description
TeaderBook is an e-reader for people learning a language through books they choose themselves. Open your own FB2 or EPUB file, tap a sentence to translate it, or double-tap a word you do not know β the translation appears right on the page, without taking you away from the text. A few public-domain classics come with the app, so there is something to read from the very first minute. **YOU CHOOSE HOW IT TRANSLATES** β’ **Offline words** β instant translation of individual words, with no internet connection and no account. β’ **Offline translation** β whole sentences translated on your phone itself, still without an internet connection. β’ **Smart translation** β the most powerful option for difficult sentences; it understands the sentence in context. Models are downloaded only when you agree to it. When there is no connection, the app does not stop working β it falls back to a method that needs none. **WORDS THAT STAY WITH YOU** Every word you look up goes into your own dictionary, along with the sentence you encountered it in and a mark showing whether you know it or are still learning it. A separate screen brings those words back at increasing intervals, helping a word move from βseen it somewhereβ to βknow it.β The dictionary can be exported and imported as CSV. **BUILT FOR READING, NOT FOR DRILLING** β’ Real pagination, not endless scrolling β and a sentence split by a page break is still translated as a whole. β’ A choice of typefaces, including OpenDyslexic. β’ Light and dark themes, plus a dimmer for reading at night. β’ See how much time is left in the chapter and the book. β’ Statistics showing how long you read and how many words you worked through. β’ Pronunciation, read aloud using your phoneβs own voice. **YOUR BOOKS STAY YOURS** TeaderBook is not a bookstore: apart from the few classics it comes with, you bring your own files. Your books, your reading position, your dictionary, and your statistics stay on your phone and are never uploaded. No ads, no analytics, no trackers. **TEADERBOOK PRO** Smart translation and Offline translation are available for free a few times a day, as is one grammar breakdown per day. TeaderBook Pro, an auto-renewing monthly or yearly subscription, removes those daily limits. Reading, Offline words, the dictionary, and reviews stay free β with no account and no internet connection. Privacy Policy: https://teader.app/privacy.html Terms of Use: https://teader.app/terms.html
