An open-source canvas application called PenEcho has been developed, allowing users to interact with AI models like GPT-5.6 directly on a digital whiteboard. This tool enables users to handwrite equations, draw diagrams, and place notes, with the AI's responses appearing alongside their work as editable drafts. The application aims to streamline the workflow for researchers and mathematicians by keeping the interaction within a single interface, reducing the awkwardness of translating handwritten work into digital formats.
