title: Software to Merge Similar Texts Like in Google Docs
body: <p>I'm developing a CMS where users can edit each others notes.</p>
  
  <p>Google Docs has a great feature where people can independently edit the same note and merge their edits.</p>
  
  <p>Is there a jQuery plugin that does something like that? More generally, is there any kind of software that does this for free?</p>
