Our Approach

Inclusivity and availability have always been central to our mission. We’ve worked hard to design and develop Hypothesis to reduce geographic, financial, or logistical barriers to users who want to read and write annotations on the web. That’s why Hypothesis is built on open web standards, will always be free to use, and works on a wide range of formats and platforms.

We consider accessibility to be a key part of a larger effort to practice and promote what many are now calling “inclusivity.” We work to increase the accessibility of annotation through inclusive design, a practice defined by the Inclusive Design Research Centre as “design that considers the full range of human diversity with respect to ability, language, culture, gender, age and other forms of human difference.” Following inclusive design, we look to make interventions not only to support accessibility for specific types of users, but to make annotation a better and easier experience for everyone.


  • Engage with users for whom Hypothesis software has failed to provide an inclusive experience
  • Real-world testing and feedback
  • Collaboration with people and organizations that care about accessibility and inclusivity
  • Standards/guidelines compliance
  • Inclusive design as an integral part of everyday development
  • Transparency: clear, public communication about the approach, status, and plans for accessibility and inclusiveness at Hypothesis
