It's a shame that the first person to review this tool basically review-bombed it with an unwarranted 1-star just for login problems. The tool is not perfect, but they clearly worked hard on it, and it deserves way more than that. So I'm perhaps being a bit generous here to make up for that bad review...but here's my honest take:

TDLR: Buy for the research capabilities and AI/plagiarism checkers.

HUMANIZING: The humanizing tool works, but it works too well in the wrong way, in that it just makes your text less grammatically correct. It tends to add run-ons and in general makes things slightly harder to read. It does remove AI cliches, but it's just not good enough yet for me to use for any article generation without more editing on my part. So I hope this gets improved. It's promising through. What I'd like is to be able to set a tone, such as "friendly but professional" or give the text a generational flair. Also, humanizing doesn't always have to mean "dumbing down." Perhaps we'll get more options in future versions?

BTW, the basic humanizing seemed to work better for me than the ultra version.

AI RESEARCH PAPERS: The unexpected value of this tool is that you can give it a topic, and it will find relatively recent research papers, with working DOI links, and correctly cite them in an article good enough to submit for homework. Obviously, you don't want to just hand in these fully generated articles, as that is cheating, and that is not my intended use. But where this does help a lot is when you need to research something and find decent citations without spending hours on end.

I've tried other AI research tools on AppSumo, including Afforai/Logically and Paperguide, and both would often fail at providing useful references. So the research paper aspect of Humanize is very useful and quite good...I'm quite excited to find this gem after being frustrated with other research software.

VERDICT: I would say give it a chance. While I was a bit disappointed in the "humanizing" so far, once I saw how well Humanize AI was able to research topics and cite them, I decided this was well worth it.
