My wife uses a simple version of a Cloze test when she teaches; she creates these tests using Word & a lot of copying & pasting.
When she saw my Quick & Dirty Cloze test with Lettering.js she asked if I could make a dedicated close test for her so I set about creating a basic webapp so that she could speed up this mundane task.
Behold the Cloze creator
Try it out yourself at zander.io/cloze-test/ & if you think it can be improved, I welcome your suggestions.
Also, I should thank a kind Stack Overflow user for giving me a hand creating this.
