I've used CHATGPT since it came out, I'm a premium subscriber, I've used it for work and all sorts of other things in my life, I've created a huge personal ecosystem in it, but I've fallen out of love with it lately. It seems like it's gotten worse.
CHAT is sloppy, it gets a lot of basic things wrong, and it even outright lies about important things. It also refuses to do basic things it's supposed to do (e.g., help crawl one of my websites and produce a copy deck). I've been using Grok a lot more lately, and while CHAT is still better for writing, Grok is much more useful and accurate imho. I think I'm going to give Gemini and Claude a try soon, I've heard good things.
As others have pointed out here, it seems Apple dodged a bullet here.
