Helping me break down annoyingly long/poorly formatted code segments so I can think more clearly about how to troubleshoot them.
Generating meal plan ideas (I generally do my own thing but having it pick out proteins for any given day of the week helps me to mix things up)
Assisting me as a GM in games for the reasons other people have already mentioned. I also have my hands on a module that lets an LLM pose as an NPC and give dialogue when spoken to that is absolutely fantastic when my players want to talk to some random NPC I don’t give a shit about.
