Oppia Actions CircleCI Join the chat at

Oppia is an online learning tool that enables anyone to easily create and share interactive activities (called 'explorations'). These activities simulate a one-on-one conversation with a tutor, making it possible for students to learn by doing while getting feedback.

In addition to developing the Oppia platform, the team is also developing and piloting a set of free and effective lessons on basic mathematics. These lessons are targeted at learners who lack access to educational resources.

Oppia is written using Python and AngularJS, and is built on top of Google App Engine.


Please refer to the Installing Oppia page for full instructions.


The Oppia project is built by the community for the community. We welcome contributions from everyone, especially new contributors.

You can help with Oppia's development in many ways, including art, coding, design and documentation.
