About
AgentEcho is a visual feedback annotation tool designed for developers, allowing them to place markers on DOM elements and generate AI-optimized Markdown reports. This tool is particularly useful in scenarios like code reviews, bug reporting, and when providing input for AI coding assistants. AgentEcho supports framework detection, automatically identifying elements from React and Angular, with plans to expand support to Vue and Svelte. The tool generates unique and stable CSS selectors and includes essential information like classes, IDs, and text content for precise feedback documentation. Users can export their feedback as structured Markdown to facilitate efficient communication with AI agents. Installation is available via the Chrome Web Store or by building from source. AgentEcho emphasizes ease of use with features such as keyboard shortcuts, persistent feedback, and a developer-friendly design. The tool is not suited for commercial distribution under its current noncommercial license terms.
