Python Django text editor model you be input for text field

I have a text field in my MySql db and it's a richtext or html field that is edited by multiple users with usual text editor tool bars ( bold, italics, subscript etc) plus two additional tools for highlighting a word and commenting and showing or accepting or rejecting trackchanges. Please see the attached image.
Only serious bidders without wasting time.
This is not a website not a Wordpress and it’s web app component.
