Best AI SEO tools?

Currently making some content for a client and I wanted to hear from people with actual experience. Does anyone have any experience with AI-Powered SEO tools? I've tried around 5 now, the best I've seen thus far is one called GREMI: https://Gremi.app and another called Jasper: https://www.Jasper.aii. There were a few others but they were just junk on product hunt that didn't really seem to do much or didn't really work.

Any one have any tools they really like ?
