How does Lexis Read work?
Upload an EPUB
Drag an EPUB file into your library. Lexis parses the chapters, keeps the original formatting, and stores your reading position so you can pick up where you left off on any device.
Tap to translate
While you read, tap any word. Lexis shows the translation in your language together with the surrounding sentence. One click saves the word along with that context to your vocabulary list.
Review with flashcards
Saved words become flashcards. Lexis schedules them with spaced repetition so the words you almost forgot come back at the right moment. Each card shows the original sentence, so you remember the meaning in context.
How is Lexis Read different from translation apps and Anki?
You could open Google Translate every time you hit a word you don't know, type it into Anki by hand, and read your books in a separate app. Lexis does the whole loop for you.
| Feature | Lexis | Google Translate | Anki | ReadLang |
|---|---|---|---|---|
| Read full EPUB books in-app | ||||
| Tap any word for translation | paste only | |||
| Saves word with the sentence it came from | manual | partial | ||
| Spaced-repetition flashcards built in | ||||
| No manual deck-building | — | |||
| AI example sentences in your book's context | Pro |

Frequently asked questions
What is Lexis Read and who is it for?
Lexis Read is a web reader for English learners. You upload an EPUB, read in the browser, tap any unfamiliar word for an instant translation in your language, and the words you save become flashcards you can review later. It is built for people who want to learn English by reading real books rather than drilling decontextualised word lists.
How does the translation feature work inside a book?
While reading, tap or select any word and Lexis sends the word and the surrounding sentence to a translation model. You see the translation in your chosen language together with the original sentence. You can save the word with one click, which adds it to your vocabulary list and queues it for spaced-repetition review.
Do my vocabulary words sync across devices?
Yes. Saved words, reading progress, bookmarks and review state are stored in your account, so opening Lexis on a phone, tablet or laptop shows the same library and the same review queue. You sign in once and the data is consistent everywhere you read.
Is there a free plan?
Yes. The free plan lets you upload books, read in the browser, translate words, and review flashcards with everyday limits that are enough for casual reading. The Pro plan removes those limits and unlocks unlimited translations, AI book recaps, and the full suggested-reading library for nine euros and ninety-nine cents per month.
What file formats does Lexis Read support?
Lexis reads EPUB and PDF files. EPUB is the recommended format — it is the open standard used by most public-domain libraries, indie publishers, and DRM-free bookstores (Project Gutenberg, Standard Ebooks), and it reflows cleanly to fit any screen with custom fonts and sizes. PDF works too and is the right choice for scanned books, academic papers, or any title only sold as PDF; the reader keeps the original page layout and word-tap translation still works on selectable text. The one format we cannot open is Kindle's DRM-locked .azw / .kfx, which is a restriction from Amazon's side.
How is Lexis Read different from a translation app like Google Translate?
A translation app translates whatever text you paste into it and then forgets the word. Lexis remembers every word you tapped, anchors it to the sentence and book where you found it, and brings it back for review at increasing intervals so the word actually sticks instead of evaporating after the lookup.
