AIPex is an open-source browser agent extension for developers and power users that automates complex web workflows through LLM-driven interaction. It serves as a technical alternative to ChatGPT Atlas by integrating Large Language Models directly into the browser environment to execute autonomous tasks.

• Executes browser automation using the Model Context Protocol (MCP) to interface Claude 3.5 Sonnet and Gemini 1.5 Pro with the Chrome DevTools Protocol.
• Performs automated accessibility testing by auditing DOM structures against WCAG 2.1 standards to identify aria-label gaps and keyboard navigation issues.
• Optimizes tab management through programmatic session handling, window clustering, and memory-efficient state persistence.
• Deploys agentic skills for multi-step web navigation, dynamic form completion, and structured data extraction from single-page applications (SPAs).

The extension is built on Chrome Manifest V3 and supports cross-browser compatibility via Chromium-based engines. It is designed for automated QA testing, competitive intelligence gathering, and building personalized AI browsing assistants.
