Tools for wordpress title capitalization

Is there a tool for automatically correcting wordpress posts' titles and headings with correct title capitalization or title case?

Let's say, if I import articles without format with title"how to eat well" and this plugin will convert it to "How to Eat Well", as well as all the h1-h6 headings with correct title case.

I only know "capitalize my title" can do this but it's a paid plugin and not 100% automatic.
