We can build something in the same spirit for your brand, school or product, and show you a free concept first.


Playwatch Academy
Playwatch Academy is a 3D learning world built for Playwatch in the US. Gabby, the guide, flies kids to Reading Island, Math Mountain, the Science Lab and the Coding Rocket, and every lesson follows the same rhythm: Watch · Read · Play · Do · Quiz.


Doris Academy
Doris Academy puts Vietnam’s full national curriculum (GDPT 2018) for grades 1–12 into one bilingual 3D world, with key points, worked examples and scored practice for every lesson. It installs like an app and keeps working offline.


DorisEdu Kids
DorisEdu Kids is a bilingual learning universe for kids aged 2 to 10: Vietnamese kids learn English and kids abroad learn Vietnamese, through videos, stories, games and voiced lessons. Ad-free and parent-approved.
