Make reading active, visible and social

Are you interested in increasing student engagement, expanding reading comprehension, and building critical-thinking and community in classes? Collaborative annotation makes reading active, visible, and social, enabling students to engage with their texts, teachers, ideas, and each other in deeper, more meaningful ways.

Start a pilot: We’ll help you with pedagogy and technology to incorporate collaborative annotation into teaching and learning.
Teaching? Start using Hypothesis in your courses for social reading with collaborative annotation.
