Google has announced a major update to Chrome DevTools that integrates a built-in AI assistant powered by Gemini. The new tool can analyze web pages in real-time, suggest performance optimizations, and even fix common bugs automatically.
Key Features
- AI-Powered CSS Debugging: Describe the layout issue in plain English and get suggested fixes
- Performance Insights: Automatic identification of render-blocking resources, memory leaks, and layout shifts
- Accessibility Audit: Real-time WCAG compliance checking with suggested fixes
- Code Generation: Generate boilerplate code for common patterns directly in the console
How It Works
The AI assistant runs locally on the device using Chrome's on-device AI capabilities, meaning no data is sent to external servers. It analyzes the DOM, computed styles, and JavaScript execution to provide contextual suggestions.
Developers can access the AI assistant through a new panel in DevTools or by pressing Ctrl+Shift+A in the DevTools window.
Developer Response
Early beta testers report significant productivity improvements, particularly for debugging responsive layouts and identifying performance bottlenecks. The tool is expected to be available in Chrome Stable by version 130.
