Very useful in powering personal learnings
i'm fully convinced this is the future of education
Matt Pocock built a Claude skill called /teach, and the whole idea is a private tutor that builds an entire customized curriculum around YOU.
think about how school works now.
everyone gets the same lessons at the same pace, whether it's too slow for you or way over your head.
but a great private tutor does the opposite.
they watch where you specifically keep getting stuck, then drill that one weak spot until it clicks.
that's what /teach does automatically.
it finds the bottleneck in your learning and breaks it, over and over, until the thing you couldn't do becomes easy.
he used this skill to learn the Rubik's cube.
it found good sources, wrote him custom lessons with diagrams and little practice drills, and kept a running record of how he was doing.
the way it knows how he's doing is simple: he just tells it. as he practices, he reports back ("i can make the white cross," or "i can mostly solve it but i keep failing the corners"), and it writes that down.
so when he said he was stuck on one specific move, it built the next lesson only for that.
the reason it can do this is memory. most AI forgets everything the moment you close it, so you're always starting from zero.
/teach saves those notes about you on your computer and reads them back before every lesson. so it remembers your goal, what you've already learned, and exactly where you're struggling, then aims the next lesson right at that.
and this works for anything. languages, chess, guitar, onboarding a new hire to a company.
you point it at a topic and it builds you a personal course that keeps adjusting to you and gets smarter the more you use it.
