LearnKraft

LearnKraft has a free plan at US$0 a month, with paid tiers at US$9.99 a month (Basic) and US$125 a month (Premium, annual billing only).

LearnKraft is an AI quiz generator that turns uploaded documents into quizzes, with autograding and proctoring mentioned for the paid side.

The free plan is small: two document uploads, a 5 MB file limit, and up to 5 quizzes.

You can still edit questions and answers, get unlimited questions, and download both the question paper and the answer paper.

Basic raises the limits to 3 uploads at 15 MB and 20 quizzes a month, and adds the classroom features.

These include student registration, one-click quiz publishing, student access to quizzes, auto grading, grade modification, quiz settings changes, and report analytics with feedback and report publishing.

Premium has the same feature list with 25 quizzes a month.

That makes the jump from US$9.99 to US$125 hard to justify unless you need those five extra quizzes.
