PenEcho: An Open-Source Canvas with AI (github.com)

PenEcho has launched an innovative open-source canvas that integrates AI into collaborative problem-solving. This shared platform allows users to draw, write equations, and create diagrams in a spatial context while the AI interprets these inputs and provides responses alongside them. With features like a large 20,000 x 20,000 pixel canvas and the ability to select different modes for various types of inquiries—Arcane, Sci-fi, or Research—PenEcho facilitates a seamless and dynamic interaction that goes beyond traditional text-based AI chats. For the AI/ML community, PenEcho represents a leap towards more intuitive interfaces for technical exploration and learning. It leverages a lightweight local runtime, using a system of cropped tiles to handle input efficiently, ensuring that the extensive canvas doesn't hinder performance. It also supports several execution modes, including Codex and Claude CLI, allowing users to run models locally or via API without compromising their workflow. This tool opens new possibilities for collaborative learning, helping users visualize and interact with complex ideas more effectively while maintaining control over AI-generated content.
