About Hypothesis
Hypothesis lets you highlight passages on a web page or PDF and attach notes that stay anchored to the text, kept private, shared with a group or made public. It is widely used in education and integrates with learning management systems.

- Private, group and public annotation layers on the same document
Limitations
