I dunno if you really need this. I asked AI to generate me a Lean tutorial with exercises and it did a really great job, one-shot with no skills. My 4th attempt to learn Lean and I'm actually making progress this time. (Mostly because you can say "I'm a bit stuck here, can you give me a hint" - it's really good at Lean even without access to the Lean compiler.)

Maybe it improves things a bit though. I might try it next time.
