Annotate any webpage UI and export feedback as Markdown
Visual feedback annotation tool for developers to place markers on DOM elements and generate AI-optimized Markdown
AgentEcho automatically generates unique CSS selectors, captures element classes, IDs, data attributes, text content, and detects React/Angular component names. Users can place markers on problematic elements and export a complete technical report without manually writing selectors or hunting for element details.
Users can hover to highlight elements and click to add feedback with visual markers that stay positioned on the page. One-click Markdown export creates a formatted report with all element context, making it easy to share specific UI concerns with team members or AI tools.
AgentEcho works on any website with no configuration, offers free source-code installation, and provides keyboard shortcuts for power users. The Shadow DOM isolation ensures it won't break page styles, making it safe to use on production sites while gathering feedback for AI-driven development.
AgentEcho lets users click DOM elements to place numbered markers, then generates AI-optimized Markdown reports with element selectors, classes, IDs, text content, and component names. This structured output helps AI assistants understand exactly which UI elements need changes and why.
