What Is Desmos AI?
Desmos is a free, browser-based graphing calculator and interactive math activity platform. The AI enhancements allow teachers to assign pre-built interactive activities where students manipulate graphs and equations in real time, and to create custom activities using Desmos's AI-assisted activity builder. For students, Desmos makes abstract mathematical concepts visual and manipulable — transformations, function families, statistics, and calculus concepts become explorable rather than purely procedural. The Desmos Activity Builder allows teachers to create interactive lessons where student responses are visible live on the teacher's dashboard. All of this is completely free.
