About Playlab
Playlab is a tech non-profit dedicated to helping educators and students become critical consumers and creators of AI.

Design and implement the core application builder where educators create AI apps using natural language
Create real-time collaboration features enabling multiple educators to co-create applications together
Build systems that enable educators to create sophisticated AI agents that work autonomously toward educational goals
Implement voice interfaces and mobile-first experiences that work from rural schools with limited internet to high-tech classrooms
