Screen Canvas

A browser extension that lets you annotate any web page by drawing on it, highlighting blocks of text, and attaching notes and color-coded markers, all for free. It solves the problem of scattered context by enabling quick capture, organization, and sharing of annotations for students, researchers, teachers, and professionals who need to study, compare, and collaborate on online content.
