It also offers services like Scientific Calculator, Four Function Calculator, Matrix Calculator and Geometry Tool. The name Desmos came from the Greek word δεσμός which means a bond or a tie. Its business model involves premium Desmos Math Curriculum and paid partnerships with publishers, assessment companies, and educational institutions.

As of April 2017, Desmos also released a browser-based 2D interactive geometry tool, with supporting features including the plotting of points, lines, circles, and polygons. Yet another use is to make music, using the calculator's auto trace function. Another peculiar use of the calculator involves the creation of graphic arts – which involves an elaborated use of curve modelling through equations and inequalities. Moreover, activity modules for classrooms can be created through a teacher account, which allow instructors to view students' work and response in real-time. A modified version of the calculator has been used in standardized tests, such as the State of Texas Assessments of Academic Readiness test, the Virginia Standards of Learning (SOL), and the California Assessment of Student Performance and Progress (CAASPP). The tool comes pre-programmed with 36 different example graphs for the purpose of teaching new users about the tool and the mathematics involved. A can then be generated which allow users to share their graphs and elect to be considered for staff picks. Users can create accounts and save the graphs and plots that they have created to them. It can also be used in several languages. In addition to graphing both equations and inequalities, it also features lists, plots, regressions, interactive variables, graph restriction, simultaneous graphing, piece wise function graphing, polar function graphing, two types of graphing grids – among other computational features commonly found in a programmable calculator. As of September 2012, it had received around 1 million US dollars of funding from Kapor Capital, Learn Capital, Kindler Capital, Elm Street Ventures and Google Ventures.

It was founded by Eli Luberoff, a math and physics double major from Yale University, and was launched as a startup at TechCrunch's Disrupt New York conference in 2011. Desmos is an advanced graphing calculator implemented as a web application and a mobile application written in JavaScript.
