PinAppAI is a visual feedback tool that transforms requests for website modifications into organized tasks suitable for AI coding agents. Users can place pins on various elements of a live website and articulate their desired changes either through simple text or voice commands. AI agents such as Claude Code and Codex receive these detailed requests, which include specific element identification, text selections, and exact visual captures. The platform offers four distinct pinning modes: free-form pins that utilize percentage-based positioning, element pins that allow for precise targeting of HTML elements, screenshot pins that create exact image captures, and text-selection pins that facilitate accurate find-and-replace tasks. PinAppAI seamlessly integrates with AI coding solutions through the Model Context Protocol, enabling reviewers to annotate directly on live sites while AI agents suggest modifications within the editing interface. It is compatible with several AI tools, including Claude Code, Cursor, Continue, Codex, and Claude Desktop. Users can access PinAppAI through various means, such as review links, embedded widgets, a Chrome extension, and a dedicated macOS application, ensuring flexibility and convenience for all types of users. This comprehensive approach empowers teams to enhance their web development processes efficiently.
