People are constantly talking about chatGPT and reinforcement learning but mathacademy is using AI to teach humans. And from my experience very effectively.

One more vote from me for mathacademy.com!

For reference, though I now work in tech, I have a physics degree from a top-10 worldwide university, and reviewing linear algebra on math academy has not only been great to re-learn things I've forgotten, I'm confident that it's taught me at least a few things that I've never encountered before.

So yeah, it's legit in my book.

I also think that one of the reasons it gets such rave reviews/etc from folks using it is that it's, frankly, not that well known yet, and we users who like it _really_ like it, so we want to see it stick around and grow further for our own use too!

Math Academy seems like it could be a game-changer for learning, it's a paid service and in beta-testing. They only cover math, though, at least right now.

In addition to presenting the topics and providing exercises, MA automates some tasks that are usually left to the learner, like spaced-repetition and tracking down prerequisite topics. They have a detailed DAG of math topics connected with dependency relations that enables this. Basically automation of a lot of what a tutor would provide.

Very impressed with what I have seen of it so far, and the founder's of it have an impressive amount of passion and drive to deliver. You can read more about it here as covered by the washington post https://www.washingtonpost.com/education/2022/10/16/math-aca...

My daughter is really enjoying it so far going through 5th grade math and working into algebra.

It's 5x as expensive as AoPS Beast Academy which trains champions of math contests. (AoPS gets more expensive for the courses after Algebra)

I used Math Academy to relearn some math I’d forgotten since initially studying it decades ago. It covers pretty much an entire undergraduate curriculum.

I was impressed with both the breadth of the courses and the efficiency gains from letting it do the scheduling and making sure I review topics just often enough to hold onto the skills.

The testimonials on the homepage are aggressively positive, what has your existence been like? I’m interested in revisiting the various University topics, particularly DiffEQ/stats/LinAlg, and have been looking for an excuse/resource to study.

My experience has been that I never fail to make progress whenever I encounter something I didn’t know or was weak in. The system offers you plenty of practice problems, at just the right level, to make sure you master the material before moving on to material that builds on the previous lesson.

Aggressively positive? Maybe. I have been a paying customer since october and very happy with the results.

Great recommendation. I'll check it out.
