Ask HN: Open source project to group website content by keyword

A couple of weeks ago there was a post here on HN regarding an open-source tool that was parsing the content of a website and then grouping the content by keyword and count of keyword.

I forgot the name the project, and cannot find either the HN post or the corresponding github page in my browser history.

Can anybody point me in the right direction where to find an open-source project for python that can parse website content and output all keywords and the count of each keyword per site?

Hopefully somebody else read that previous HN post as well and can post the URL. Thanks in advance!
