AI Math Notes is an open-source interactive graphing application that allows users to draw mathematical equations on a canvas. The application leverages multimodal large language models (LLMs) to calculate and display the results. Developed using Python, it utilizes the Tkinter library for creating the graphical user interface and PIL for image processing. It was inspired by Apple's 'Math Notes' showcased at the 2024 Worldwide Developers Conference (WWDC).
