title: Automatic text / HTML annotation / highlighting
body: <p>Nowadays there are softwares which, when provided a text or a html document page, will output a summary.</p>
  
  <p>I wonder if there exist anything to automatically annotate (or at least highlight) the same documents. </p>
  
  <p>The idea is to be able to keep the full text, but highlight the most meaningful parts (somehow like a summarisation tool would do I guess). And maybe provide additional inferred insights (?)</p>
  
  <p>Also I would like to know how it works if it exists :) Would it really be very different of summarization, or is it just the same principles with a different "output format"?</p>
  
  <p>I'm looking for something to annotate HTML documents, like AnnotatorJS is designed for, looking like this:</p>
