AIQuizzes

https://aiquizzes.com offers a set of spaced repetition prompts aligned with Fast.ai video lectures. It’s a distant an implementation of the Mnemonic medium, although not really integrated with the source material (and the source material was not written alongside the prompts).

The prompts themselves strike me as quite poorly written (see What are the most important attributes of good spaced repetition memory prompts?):

One interesting property of this system is that each prompt is “backlinked” directly to some piece of the corresponding lecture.
