Lexis is a reading-companion web app for English learners. Read EPUB books in the browser, tap any word for a translation in your language, and review what you save with adaptive flashcards.
Lexis combines an EPUB reader, a translation lookup, and a spaced-repetition flashcard system in a single web app. You upload a book, read it in the browser, and tap any unfamiliar word to see an instant translation in your language together with the surrounding sentence. Saving a word adds it to a personal deck that resurfaces on a spaced-repetition schedule, so every word you tapped while reading comes back at the right moment for review.
Most language-learning tools split the work into three apps: a reader, a translator, and a flashcard tool like Anki. The split is the problem. Words you looked up in a translator disappear after the lookup. Decks built by hand in Anki decay because building cards is slow. The original sentence — the strongest memory cue — is lost in both flows.
Lexis keeps the loop closed. You read a book, tap a word, save it with the sentence attached, and review it later. There is no separate deck to maintain and no context to reconstruct. The book and the vocabulary stay connected, which is how memory actually works.
Lexis is a small independent project built by a solo developer. The product is the work, the roadmap, and the support channel. If you have a question, a bug, or an idea for a feature, the same person reads the email.
