Hypothesis

What is Hypothesis?

Hypothesis is a collaborative annotation tool, which is free and open to use for everyone. It allows you to annotate anywhere on the web by selecting text via a publicly viewable URL, selecting a file from your Canvas file repository, selecting a PDF from Google Drive, or selecting a PDF from OneDrive. Annotations can be created together in groups or individually, and one can reply to or share publicly or privately.

Hypothesis facilitates active reading while nurturing students to engage socially with contextual ideas and achieve a deeper understanding of readings.
