Another good AI use-case: cleaning up notes. What I've written in my scratch pad (https://motate.app/@sblue/linalg-exam-2-notes-755e73c1-8ddc-...) would be unusable as a reference at exam time.

But I was able to AI generate an audited and cleaned up 2 pager based strictly on my notes (https://github.com/stonly/public_share/blob/main/linalg_exam...)

Word of caution: A few versions ago of the models (and myself), I learned a hard lesson about generating reference guides. My physics exam performance paid the price. So this is not without risk as with anything AI, and your prompt mileage may vary.
