> Amplify (neé Desmos)

It looks like "Amplify Education, Inc" and "Desmos Studio" (Public Benefit Corporation) are separate entities.

The desmos website still shows that most of the Desmos "math tools" still exist under the Desmos name (graphing calculator, scientific calculator, four function, matrix, geometry, 3D), but that "Desmos Classroom" specifically has been renamed to "Amplify Classroom" [1].

The amplify usage guidelines [2] say that "Amplify does not own but partners with Desmos Studio, the maker of a suite of free math tools, including a graphing calculator used by over 75 million people around the world. (See desmos.com for more information.)"

Same! It’s one of those projects where as soon as I scroll the landing page, I can hear the fireworks of ideas going off in my head! It seems to work really well on mobile as well. I think it’s got real visual aesthetic appeal - it takes me right back to the handdrawn colour diagrams in the textbooks when I was at primary school.
