What is oodlü?

oodlü Worlds is a 3D space where learners create, play and learn in worlds that feel instantly familiar, much like the creative games they already love. They build the worlds themselves with simple tools, so no technical skills are needed, and they're engaged from the start.

Parents and teachers stay in control, adding learning content for any subject, age or curriculum. Every group is closed and managed by adults, with safety designed in from the ground up. It's quick to set up, easy to run and grounded in research.

A world built by students

Students design and build their own islands inside oodlü, then explore worlds built by their classmates. Every build doubles as practice in problem-solving and creativity.

Curriculum-aligned challenges

Challenges and games are mapped to the curriculum, so time in oodlü lines up with what's being taught in the classroom, not a separate add-on.

Insight for teachers

Teachers can see who's taking part, what they've completed and where they might need support, without extra marking.
