My memory wasn't this bad before, was it?

Maybe it's just because I'm more invested and spending more time on it than before, making me feel this way? But lately, it feels like the AI's forgetfulness is getting worse and worse. If it's not just in my head, I need to do something about it, but I don't know what. I don't want to spend money, so should I just give up, or should I look for another AI chat with better memory?
