Persuall is a collaborative annotation tool for technical papers. It’s free.
You upload a PDF or a Web page and send the Persuall URL to your students.
Your students then read and electronically markup the article.
Perusall’s AI will then grade the annotations based on amount, distribution, and quality!
Furthermore, it will produce a confusion report, highlighting the three parts of the paper that have led to the most confusion together with the three annotations that convinced the AI of that conclusion.
