A browser extension for mapping arguments appearing in web pages
The Sophistree browser extension lets you map and critique arguments appearing in web pages. Highlight text from a webpage, add it as an excerpt to Sophistree, and it will appear in a graph in Chrome's sidebar. Add and connect additional excerpts to get an overview of the page's argument. Add your own arguments about the truth of what you see and Sophistree will highlight both the graph and in-page highlights to emphasize where the argument is strong and where it is weak.
Sophistree now has experimental PDF support! Please report any issues using Github.
Sophistree is open source software, available at https://github.com/carlgieringer/sophistree
