In 2015, as part of a job interview for the amazing team at MerryBiz, I put together a python script that uses a supervised learning algorithm to classify documents into one of several categories. Rather than writing a simple blog about the demo, I decided to wrap the application in a small website and put it out for the world to use.
Classy accepts zip files containing folders of text files, where each folder is a classification. Classy then gives you an endpoint where upload new files and let Classy classify them for you. The website itself is a small wrapper for a REST API, and so you can also integrate the Classy API into your existing web service.
Head over to https://classy.foursails.co/ and give it a try to today.
