Sophistree is a free browser extension designed for Chrome, focused on mapping and analyzing arguments found within web pages. Users can easily highlight text from any webpage and add it to the Sophistree interface, where it is represented graphically in the sidebar. This feature allows for a visual representation of the arguments presented on the page, making it easier to understand the structure of the argumentation.

In addition to mapping existing arguments, Sophistree enables users to contribute their own insights and critiques. By connecting various excerpts and personal arguments, users can create a comprehensive overview of the discussion. The extension highlights both the strength and weaknesses of the arguments, facilitating a deeper analysis of the content encountered online.
