ooh, does that help? or does it hallucinate a lot?

I made this for myself a while ago: https://rewardsgenie.calstudio.com/ it's a tool that tells me what's the most rewarding credit card to use for any purchase, but even with good context, it would sometimes make stuff up so I kinda stopped caring

It's pretty low risk and I'm just doing it for saving a few bucks. So far it has only had one moderate oppsie that I caught. It recommended a kefir brand that it turned out was actually low fat (which I didn't want), but in defense of the AI, I had also read the entire package and didn't see the tiny low fat words written on top of the pink cap either. I only noticed when I started drinking it and went back for a closer look.

I tried to checkout your tool, it starts with an account though and I don't have many CC. It sounds like it sound be useful though if you have those stacked deals like 3% cash back but 8% cash back on Tuesdays for gas only and then another card that's 5% cash back every day. I agree it's a good amount of context to keep track of though.
