Der Tag war vergangen, wie eben Tage vergehen; ich hatte ihn hingebracht, ich hatte ihn sanft ; ich hatte ein wenig gearbeitet, in alten Büchern geblättert.

Ich hatte zwei Stunden lang Schmerzen gehabt, wie sie ältere Leute haben.

How it works

Three steps to fluent reading

01

Import a book or text

Drop in a file or paste a link. We'll parse it into a clean reader instantly.

02

Click and save while reading

Tap unknown words for context-aware translations and save them with one click.

03

Review and retain

Spaced repetition resurfaces words at the perfect time, until they're truly yours.

Why Lexula

Not another app with exercises.
A calm reading workspace for real language.

The old way

The usual workflow splits between a book, dictionary, translator, notes and flashcards.

  • Repetitive drills disconnected from real life
  • Toy sentences you'll never actually say
  • Vocabulary that vanishes a week later
  • Gamified streaks that don't build fluency

The Lexula way

One calm reading flow: translate, save and review — without switching apps.

  • Read books, articles, and stories you love
  • Learn words in their natural context
  • Save and revisit only what matters to you
  • Spaced repetition that makes words stick

The reader

A reader that stays out of your way

Translation, dictionary and review appear only when you need them — without breaking the rhythm of the text.
