WPAutoBlog is excellent. Real value for money, delivered instantly.
If you have a business case for it it's a no-brainer.

Here's how things went.

1- I tried the system with their free trial.
There was some initial struggle to connect to WP because I used an old test site with an older version of WP and no domain name. The system did not like it to I attached a domain name and upgraded WP - connection then worked fine.
Got 3 articles which seemed reasonably good but not great, a bit generic.

2- I created another trial account.. This time I was able to fine-tune the output using a better keyword (actually, a rather long phrase) and a more detailed prompt (I asked to include references and quotes from well-known authors).
The result (in french) was published on the website in a matter of minutes.
I could not believe what I was reading. The structure was good. The tone was good. The content quality was good. It did not feel like AI. The quotes felt on point.

3- I know that plagiarism / AI checkers are not great but some people use them.
- I used GptZero on the last test article and I got this : 'We are uncertain about this document. If we had to classify it, it would likely be considered human. 77% Human, 0% Mixed, 23% Probability AI generated"
- Then I used plagiarismdetector.net and got this : 97% unique, 3% plagiarized.

4- I bought 6 codes right away

I'm kind of surprised by the deal, getting 500 long form articles LTD for that amount of money is really cheap. In the questions, the author mentions that he gets 5-figures monthly income from subscribers. I wonder why they are on AppSumo then. I guess there's an advantage for them but what? Anyhow. Well done guys.

A bit of background :
- I have been been doing SEO professionally since 2007, I used to own a copywriting agency and at some point I was deputy editor-in-chief of an international magazine
- I've been through quite a bit of AppSumo deals, some terrible, some good, and a few really excellent.
- I use pro versions of ChatGPT, Claude, Perplexity and my own lama-based model for generating content. I'm very familiar with AI, LLMs and prompts, so I know what to expect from an AI tool. My expectations were low.
