Verso – Vocabulary Builder

Verso is a vocabulary notebook you build yourself — one word at a time. Whether you're reading a book, watching a show, traveling, or just noticed an interesting word around you, Verso makes it effortless to capture it and actually remember it. Add the word, let AI fill in the meaning, an example sentence, and a translation, and it instantly becomes part of your personal study deck.

WHY VERSO • Build your own word book. The words you save are the ones that matter to you — from the novel on your nightstand or the sign you walked past today. • Learn for the long term. Verso schedules reviews with a proven spaced-repetition system (FSRS), so hard words come back sooner and easy ones later. Your time goes where it counts. • Let AI do the busywork. Tap once and Verso writes the definition, a natural example sentence, and a translation — even the correct article for gendered nouns.

CAPTURE WORDS ANYWHERE • Reading a book? Jot down new words as you go and review them later. • Out in the world? Save the words you see and hear before you forget them. • Studying a language? Keep separate wordbooks for each language you learn.

FEATURES • Personal wordbooks — group your words however you like. • AI autofill — meanings, example sentences, and translations in one tap. • Today's Words — a fresh set of level-calibrated words (A1–C2) to grow your vocabulary every day. • Spaced-repetition study — flashcards that adapt to how well you know each word. • Pronunciation — hear how each word sounds. • Many languages — study English, Spanish, French, German, Italian, Portuguese, Japanese, Chinese, Korean, Russian, Vietnamese, Thai, and more. • Optional account — start instantly as a guest; sign in with Apple or Google to back up and sync across devices. • Your data, yours — everything works offline and stays on your device until you choose to sync.

Verso is for self-learners who'd rather build a vocabulary that's personal and lasting than memorize someone else's list. Start with the next word you read.
