Fwiw, I stopped using ChatGPT and went to a competitor because the checks slow down ChatGPT so much that the webapp becomes unusable in anything but a new short chat. CPU usage goes to 100%, you can't type, the entire tab freezes, etc. It's a miserable experience to use and I'm on a relatively new MacBook not some old computer. If you read around it's a very common problem people have been having for a while now.
