I've been an enthusiast for several years and have helped develop a discord role playing chat bot. I use AI for software development, cocktail recipes, fiction, and just general brainstorming. I use it a lot and pay for plus, but I'm pretty wary about what it has to say—particularly when asking for advice or opinions.
I also use local AI from time to time but it can't really compare with ChatGPT. And I use NovelAI which is pretty handy for co-authoring stories.
I used it just today for some resume tweaking help. It was good at pointing out things that could be improved, but not so great at actually improving it. It frequently does not follow its own advice, but that's the nature of AI.
