I used to make qol autohotkey scripts for games I played. Take available info on the screen, make notifications or block input at the right time. Stuff like that.

For example, I made an on-screen mini-map and arrow to guide me instead of having to repeatedly read coordinates from a chat.

Playing a ping when something happened on screen was the most basic i did.

I had more fun making my scripts than actually playing the games. It's fun looking for small queues on the screen and then figuring out practical ways of using that. I didn't need AI for this.
