Hi Melvyn, what's the reason you want to humanize the AI generated text?
For SEO reasons or so readers don't suspect AI wrote the blogs?
If the former, you don't need to worry about that. There's no research that shows that AI generated blogs negatively affects SEO. Search engines prioritise quality content over AI vs human generated. Also AI humanizer APIs work to be undetectable but makes the writing trash so wouldn't recommend them. I've tried many and they all suck.
If the latter, you can use a prompt to make the blog sound like a human wrote it. I have that in some of the templates that you can copy-paste.
