Content marketers in the digital marketing space commonly put blog posts through "spinners" that take your text and modify it through replacing words/phrases with similar equivalents. This lets you take one article and turning it into 5-10+ unique ones, even though they still discuss the same things. It would be a shame if a service like this was marketed towards those interested in privacy, it would probably break this entire system...

I’ve found plenty of articles that seem to be run through these spinners, but hand made corrections are likely to be necessary (unless it can be automated with ML for example) as you can almost always tell that something is odd based on context lacking word choices

And thats exactly what newer programs do, look at AppSumo and its practically all of them. The older gen simply used a giant dictionary, then picked a random option from the list of acceptable choices.
