Tools like AI Realms?

I just came across an add for AI Realms, and I found it a lot easier than trying to come up with things on my own (I'm not very creative), but it only has standard Warlock, and I want to do a Hexblade. Also, it has limited messages, and while I'm okay with paying if needed, the lack of Hexblade info has me concerned that it won't work with Hexblade. Are there other options like this?
