The AI study assistant in Discrete Math Calc is powered by API capacity generously contributed by volunteer developers who support this project's goal: making a free study tool available to more students.
Each contributor's API key is used only through this app's server-side proxy, is never exposed publicly, and can be swapped or revoked by its owner at any time from their own Google account with no code changes required on this project's side.
Thank you to everyone who has contributed capacity to keep this assistant available and responsive:
