Playwriter connects AI agents to a user's existing Chrome browser via a browser extension and CLI tool, enabling browser automation through the full Playwright API while preserving existing logins, extensions, and cookies. It provides tools for session management, page navigation, element interaction, and state persistence across multiple automation commands executed against the same browser instance. This solves the problem of fresh Chrome instances being memory-intensive, lacking authentication context, and easily detected by bot protection systems.
