Name for web applications that run in the clients browser only?

I have a very simple question: Is there a name for a web application that runs completly in the browser using Javascript and does stuff, that normally only a desktop-application would do. I made a website, that classifies scan-data using Machine Learning and it works with TensorFlow.js and many js-libraries. Now I need the name for that kind of application for the docs. I know there was a name, but I am too dumb to find it on google again. I want to write something like "MalSCC is a client only/javascript only application for classification of scan data" or something like that.
