PromptBoard

About

PromptBoard serves as an intuitive visual context buffer, enabling seamless communication between users and AI agents. Instead of laboriously describing complex UI issues, architectural blueprints, or data flows in text, users can simply snap screenshots, sketch ideas, and annotate directly on a digital whiteboard. This visual input is then transmitted to AI agents via the Model Context Protocol (MCP), allowing for richer, more efficient interactions and problem-solving, particularly useful for developers and designers working with AI assistants.
