Rank Math SEO Plugin in Automatic SEO Content (own wordpress plugin)

I am looking for a solution in which I specify keywords as variant 1 and variant 2 and it should write automatic texts which also automatically fill out the complete plugin. makes everything independent; H1-H6, title, tags ect..

So that this landing page is automatically generated using only these keywords and can be edited again at any time.

I would like to use this as a WordPress plugin.
