Pinta is a Chrome extension designed for developers to annotate their running web applications and seamlessly integrate changes through an AI coding agent. With features such as drawing, selection, and inline editing, users can easily capture and modify elements on their web pages. The tool allows for live updates as changes are made, providing a structured CSS payload for various frameworks. Additionally, it supports multi-project management and per-page annotations, enhancing collaboration across multiple routes in single-page applications.

The extension also includes standalone functionality for testing deployed staging URLs without requiring a project on disk. Recent updates have introduced built-in modules for integration with GitLab, markdown import capabilities, and persistent annotation features. Annotations remain local to the user's machine, ensuring privacy and security. Pinta is open source and licensed under MIT, making it a valuable resource for developers seeking to streamline their web development workflow.
