How to Make Blanks in Any Text
Three steps from raw text to a graded gap-fill exercise. Most users finish their first one in minutes.
Paste your text
Any passage works: a reading text, lecture notes, song lyrics, definitions. Any language, including accented characters.
Click words to hide them
Each clicked word becomes a gap. Turn gaps into typed answers or multiple choice, add hints, and accept alternative answers.
Share the link
Students open the URL on any device—no accounts, no installs—and answers are graded the moment they submit.
