Read Dutch without losing the words you look up

Look up unfamiliar Dutch words while reading. Every lookup becomes a flashcard automatically — no decks to build.

Try it — look up a word

Here's what happens after you look up a word:

For example, verzot:

2Saved to your words
3Review it later

Cards are scheduled for you — come back when it's time and see if the word stuck.

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

  1. Read a Dutch book, article, or webpage.
  2. Look up an unfamiliar word — on the website or with the Chrome extension.
  3. The word is saved automatically with its meaning and an example sentence.
  4. Come back the next day to review only the words you actually met.
