It is now possible to use Hypothesis, a free and open source collaborative annotation tool, in your Canvas course. You could use this for activities in which your students collaboratively comment or annotate web sites, documents, and other items. See this tutorial for how Hypothesis works, and here are some quick start guides for teachers and students.
Installing and Using Hypothesis in Canvas
This saves you and your students time by allowing for single sign-on use of Hypothesis:
The Hypothesis LMS app automatically provisions accounts for all students enrolled in any course using the app. This means that students can navigate to a Hypothesis-enabled reading and begin annotating without ever creating or logging into a separate account. Even better, the entire course roster of students and teachers will all be joined and annotate by default in an automatically-created private Hypothesis group that matches the course in the LMS.
Gradebook integration is a feature planned for the future.
