Inline Comments in Squarespace Blog

Dear Community,

I am exploring options to enable in-line comments in a squarespace-based blog.

Ideally, a user would mark the text section they are interested in commenting on and be able to comment directly on that section. The comment would then display on the side or just as a small note that someone commented on this section and be displayed on click. 

Does anyone have experience with such an implementation/knows a tool that allows this?

Website is on 7.1

This is an awesome idea. Did you get anywhere with it @Ferioux?

I think in-line blog commenting is a sweet why to drive better interaction and better content.
