Oppia makes it easy to create interactive explorations that educate and engage.

Explorations are interactive lessons that provide more immersive experiences than static videos or text, helping users learn by doing.
Explorations are simple to create. They are easily adapted based on individual student feedback and trends in the experience of your learners around the world.
Oppia lets you create and share explorations on a wide range of subjects, limited only by your imagination.
