Chat GPT can actually tell you if a thread that you are interested in updates with new posts, all you have to do is say.

Hey chat GPT follow the following thread at this URL and tell me anybody post any replies to it check it every hour (direct URL to the Post)

It can only go as low as once an hour but it will check it every hour and alert you you can even have it turn on a notification that will pop up on your phone.

Just a trick I figured out
