Anyone using Claude Code as a personal AI tutor (not just for coding)?

Been seeing more people build DIY "AI tutor" setups on top of Claude Code — probing what you already know, planning a learning path, then teaching step by step instead of just answering questions on demand. Curious if anyone here actually does this for learning something outside of programming (math, physics, whatever). If you've built something like this: what's your setup, and what's still annoying or missing about it? If you haven't but wish you could — what's stopping you? Time to set it up, don't know where to start, something else? Not selling anything, just trying to understand how people actually use Claude for learning before I go build the wrong thing.
