Playlab is an open, non-commercial platform — incubated alongside one of the original creators of Scratch at MIT — where educators design AI applications in plain language, without writing code. A teacher can build a working tool in under 60 minutes: a curriculum-aligned lesson planner, a feedback assistant for students with special educational needs, a multilingual conversation partner, or a Socratic tutor. Apps can be forked, adapted, and shared by a global community, mirroring the remix culture that made Scratch transformational. Playlab is guided by six core values — Agency, Play, Fieldwork, Edges, Safety & Transparency, and Commons — and integrates multiple frontier LLMs (OpenAI, Anthropic, Meta) under agreements that protect teacher and student data; nothing is shared back with providers for training.
