The dictionary that remembers the words for you — and the flashcard deck that builds itself from whatever you read, in English, Italian, Spanish, French, German, Dutch & Bulgarian.
Looking up a word is easy. Remembering it later is the problem.
Dictionaries explain a word once, then it's gone. Browser translators don't build a vocabulary history. Manual flashcards interrupt your reading. Word Holder keeps the words you naturally encounter so they're still there a week later.
From reading to review, automatically

The word is saved automatically with its meaning and an example sentence.
Come back the next day to review only the words you actually met.

Work & study reading
Build a vocabulary from the texts you already read for school or work.
Academic & professional

Not another flashcard deck
Every lookup becomes a flashcard automatically — no decks to build.
Vocabulary comes from real reading, not generic word lists.
You only review words you actually needed in context.
Unlimited reviews and quizzes — we don't ration your studying.
Designed for people who already read in the language they’re learning, not beginners.
Start reading. We'll remember the words for you.

Nothing third-party runs in your browser — no trackers, no ad scripts. We keep basic first-party usage on our own servers to run and improve Word Holder, and we never share the words you look up. Accept to turn on fuller analytics too — either way, the app works exactly the same.
