I don't know what BERT is briefly looked it up. I also looked at the site the pulsing varying color intensity targeting certain words.

Is this like a summarizer or no? I have been passively looking into ways to scan threads like in HN on popular articles and a visual tool like this could be neat via Chrome Extension.

It just seems like people's summaries are different. Although I suppose standardized tests wouldn't work if there wasn't some consensus on the point of a paragraph.
