What is harper exactly? I have tried to Google it but I am not found anything RSS related.

Indeed I am human ! (That’s what a bot would say 🤖)

Mostly no AI. I use it to review doc because I make a lot of typo / spelling error as English is not my first language. Recently I also used it to accelerate writing test cases but that’s all.

This is not a recent or “fast” projet, I have been slowly improving it for 3 years now :-D
