What it does

Takes any text and knocks out the words that matter — key terms, names, numbers — leaving blanks for you to fill in from memory. Answers stay hidden until you check. If pure recall is too hard, turn on the word bank (all missing words listed, you place them) or first-letter hints.

Why cloze exercises work

A blank in the middle of a familiar sentence is a precise question: it asks for exactly the fact you're supposed to know, inside the context where you learned it. That's why language teachers have used cloze tests for decades — they test recall, not recognition, and they're brutal at exposing what you only think you know.

Ways to use it

  • Language learning — blank out the vocabulary or grammar forms in any text at your level.
  • Definitions and terminology — blank the terms in your own lecture notes and refill them the night before the test.
  • Teachers — hand students the same passage you just taught, with the key words missing.
  • Music, poetry, scripture — memorize lyrics or verses line by line, with fewer hints each round.
  • Numbers and facts — blanks are merciless with dates, dosages and formulas: you either know them or you don't.

How it works

  1. Paste the text you want to practice.
  2. The exercise appears with the important words replaced by blanks.
  3. Choose your difficulty: no hints, first-letter hints, or a word bank.
  4. Fill everything in, then reveal the answers and see how you did.
