Oppia is an open-source project whose aim is to empower learners across the globe by providing access to high-quality, engaging education. We envision a society in which access to high-quality education is a human right rather than a privilege.

The web version of Oppia currently provides a growing curated set of lessons on Basic Mathematics, together with tools for creating them and augmenting them with translations and voiceovers to support learners who don’t speak English and learners who are less proficient at reading. VisitOppia.org to access these lessons.

Oppia Web is written using Python, Typescript, and Angular.
