Desmos is a collection of interactive, web-based math tools — most notably its graphing calculator — that runs in any browser or mobile app. It includes graphing, scientific, geometry, 3D tools, and classroom activity creators.
It replaces expensive physical graphing calculators with free, intuitive digital tools used in classrooms worldwide. You can visualize equations, interact with parameters, build custom lessons, and engage students in math exploration.
You access tools directly in your browser or via free iOS/Android apps. The graphing interface lets you enter expressions, plot multiple functions, adjust sliders, and animate variables. Teachers can create and assign interactive activities and track student work via optional classroom features.
