Browser Annotations is a Chrome DevTools extension designed to streamline the feedback process for developers and teams. It allows users to select elements on any website, add detailed feedback, and send it directly to coding agents like Pi or Claude Code sessions. This functionality is implemented without the need for any project setup, making it accessible and user-friendly. Users can easily annotate elements, making collaboration more efficient in web development tasks.

Key features include the ability to copy annotations as markdown, attach screenshots for better context, and access full context information such as element selector, position, size, and device info. Additionally, the tool supports source mapping for React and Svelte, enhancing the development process. Users can also perform batch annotations, which allows them to annotate multiple elements across different pages and send consolidated feedback, significantly improving workflow efficiency.
