Example Made from this short text:
Plants make their own food through photosynthesis. Inside each leaf cell, chloroplasts hold a green pigment called chlorophyll, which absorbs sunlight. In the light-dependent reactions, that energy splits water and releases oxygen into the air. In the Calvin cycle, the plant then uses carbon dioxide from the air to build glucose, a sugar it can store or burn for energy.

What is a fill in the blank generator?
It turns a text into cloze exercises: sentences with a gap for the student to fill. ReadLoudly writes them from your own PDF, Word file, EPUB or slides, one blank per sentence, with the answers kept in a separate key.
One blank per sentence
Each sentence has a single gap, so every item checks one word or phrase.
Optional hints
A short hint can sit under a sentence to help students who are stuck.
Student copy and answer key
Print or export the sentences without answers for the class, and the key with them for you.
Share without answers
A share link shows students the sentences and hints only.
