WordHero is pretty decent and provides loads of different copywriting options whether for emails, ads, fictional story ideas and more and is helping me on a personal project. They also seem to add new features quite regularly. It's been a valuable tool when it comes to brainstorming ideas too. Review collected by and hosted on G2.com.

The long form editor, again while it's pretty good, does seem quite generic in output. (Note that I've only just started to play around with this feature, so maybe it's me.) Like any AI writing tool, I think they're a good starting point and great for ideas. It's important put add your own personality to anything it suggests (as well as fact check etc), that way you're creating value for the audience and something unique.
