Refold is the new project from Matt who was the original creator of the Mass Immersion Approach method. It carries on pretty much the same philosophy and methodology.

The website and method are extremely cultish and some of their followers can be some real vocal fans with a cult of personality around Matt himself, but still they have some solid ideas that they try to panhandle you as this new groundbreaking method.

Nonetheless, there’s some good resources for Anki and similar tools that might be worth checking out.
