tools like Casper... has anyone ever tried?

I am looking at some tools like casper
https://caspercontent.com/

but there a tons of them. RankPill is another one...

they promise to automatically build optimized articles to boost views from google.

Has someone experienced?

Casper is one of those newer AI SEO/content tools that automates a lot of the boring parts , keyword research, SERP intent analysis, content drafts, and even publishing workflows , so you can crank out optimized articles super fast without manual edits. It’s different from old‑school toolsets (Ahrefs/Semrush) because it builds the content pipeline, not just reports on metrics. Lots of folks pair it with deeper backlink and competitor tools though , no magic all‑in‑one yet.
