About
nufa is a clean, quiet reader for books in any language, whether you know it well or are still learning it. Tap any word for an instant translation. Ask for an explanation when a sentence resists you. Save what you want to remember. Nothing interrupts the page. Open your own EPUB or PDF, or start with a free classic.
The book comes first. Translation, explanation and vocabulary wait until you reach for them, and leave the page as it was. No ads, no streaks, no daily targets.
A READER YOU CAN LIVE IN
• Light, sepia and dark pages, and a dark mode for the whole app
• Serif or humanist type, with adjustable size, line height and margins
• Focus mode hides everything but the page
• Works offline: your library, your books and your vocabulary need no connection
TAP TO TRANSLATE
• Tap a word or select a phrase for an instant translation
• Pronunciation and part of speech, so you learn the word and not just the gloss
• Hear the word spoken, in your device's own voices
• Read on. The translation sits over the page and leaves without a trace
ASK FOR AN EXPLANATION
• AI explanations of what is happening, why the line matters, the grammar behind it and the cultural context
• Built for real literature: old words, dense passages, idioms and allusions
• A page summary when a whole passage is the problem
YOUR BOOKS, OR FREE CLASSICS
• Import your own EPUB and PDF files. They are opened on your device and never uploaded
• Or choose from more than 8,000 free public-domain classics in 11 languages, from Austen and Hugo to Natsume Sōseki and Premchand. One tap and you are reading
• Pick up exactly where you left off, book by book
BUILD A VOCABULARY THAT STICKS
• Every saved word keeps the sentence you found it in
• Optional spaced repetition review, on your schedule, never a streak
• An atlas of your vocabulary, book by book, so you can see what each one taught you
WHO IT IS FOR
Readers. Someone reading in a language they are still learning, someone taking on a classic whose words are a century old, or someone who simply wants a calm page and help only when they ask for it.
NO GAMIFICATION
No streaks. No daily goals. No notifications telling you that you have fallen behind. Read three pages or three hundred, skip a week, come back.
