Signing in with Google is optional. LexiByte requests only the drive.file scope — it reads and writes only in the LexiByte folder it creates, to store your own books and reading data. It never touches your other Drive files. See our Privacy Policy.
One reader, one lasting reading profile
One parent account, a profile for each child
Teachers assign class reading, a whole class together
Tap a word or phrase for a translation and explanation that fits the sentence — learn a language in context, not as isolated words.
Read your own PDF books; or paste a web link and turn an online article into a lookup-ready, quiz-ready PDF.
After each chapter, AI generates comprehension questions; you've read it only once you understand it — skimming becomes deep reading.
Words you looked up flow into a review deck — walked through and spaced out so new words actually stick.
See how many words you know and how your reading speed changes — progress you can see, as encouragement, not a grade.
Parents or teachers set a reading plan; members see each other's progress and cheer each other on — reading together keeps momentum.
The OpenDyslexic font makes reading easier for dyslexic readers; guided, timed and free modes fit every reading situation.
LexiByte helps people learn languages by reading real books. You read books — public-domain titles, PDFs you upload, or web pages turned into PDFs — in any of 15 languages, with tap-to-look-up vocabulary help, in-context explanations, pronunciation, and AI-generated comprehension quizzes each chapter. A LexiBot assistant gives hints, not answers. Individuals keep one profile; families and (soon) schools can set reading tasks and follow shared progress. Reading is always free and never locked — you only pay for AI help with new books.
An AI reading companion for learning languages by reading real books: tap a word for an in-context explanation and translation, take an AI comprehension quiz each chapter, and follow your progress.
15 languages including Chinese, English and French — both the interface and the coaching follow your language.
Reading is always free and never locked — guests can read public-domain books without signing up; you pay only for AI help with new books. See the pricing page.
It's in planning. We're polishing the family version first; the school version will follow once we have real users. Teachers who'd like to pilot, write us at contact@lexibyte.app.
The 🔊 on a word card reads aloud with your device's built-in voice. The default is often an old "compact" voice that sounds robotic. Spend a minute installing the "Enhanced / Premium" neural voice and it sounds close to a real person — set once, works everywhere. LexiByte then picks the best installed voice automatically; nothing to configure in the app.
