Best inventory reimbursement tool for Amazon in 2023?

I used to use amzrefund to calculate my reimbursements, and they didn’t take too much.

For some reason, they’re not around anymore, and the alternatives like GorillaROI and GetIda I hear are not reliable nor easy.

Any tools or scripts out there anyone might recommend?

I’ve heard chatGPT suggested as an option, but not sure how to approach that.
