Every Spanish word looked up. Kept. Remembered.

The dictionary that remembers your Spanish words for you — a flashcard deck that builds itself from whatever you read.

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 Spanish 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.

Reviews are scheduled by an SM-2-based scheduler — the same family that powered Anki — so each word comes back right before you forget it.
