Reinforz

Reinforz has a free Starter plan at $0 a month, plus a Premium plan at $12 a month. Reinforz is an AI quiz generator and question generator that turns passages and uploaded files into quizzes, collections and reports for educators and learners.

The free Starter plan gives you 150 RZC credits a month, GPT-3.5 access, and up to 10 questions per generation from a passage of 7500 characters.

Uploads are capped at 5 MB, quiz exports are unlimited but PDF only, and your quizzes, collections and reports are public.

Reports also expire after a limited time.

Premium raises the credits to 2500 a month and switches to GPT-4.

You can generate 25 questions at once from passages up to 60000 characters, upload files up to 25 MB, and export in PDF, MD, DOCX and other formats.

Quizzes, collections and reports can be private as well as public, and reports never expire.

The free tier is enough to try the workflow.

Anyone who needs private material or longer source text will hit its limits quickly.
