Our Mission

To help anyone learn anything they want in an effective and enjoyable way.

Meet Oppia

Oppia is a free, open-source learning platform. Full of interactive activities called 'explorations', Oppia helps curious minds learn and teach.


Oppia recreates the experience of one-on-one tutoring. It adapts to your needs and lets you learn in the best way possible — by doing.


Oppia enables you to share your knowledge with people worldwide. Anyone can create and contribute to an exploration. Find out more in our participation playbook.
