Would you use an AI based blogging automation platform?

Every time I launch a new product, I feel the need to have a distribution channel but I fail at promotion miserably. Blogging is the only thing which sort of works well for me.

A month back I had this idea that I could use a platform which researches for new blog post ideas, writes it, improves it in term of seo and posts to my blog.

Do you think a platform like this would be useful or you know any such platform? I want to stay away from content writing platforms like copy.ai, writesonic etc, since I want something entirely focused on blogging use case.
