The Dev-Intelli Chrome Extension (aka Trace) is a side-panel companion that gives you AI-powered observability directly inside your browser. It uses the Chrome DevTools Protocol (CDP) to inspect, debug, and fix pages in real-time.

​
🚀 Installation

(Currently in Developer Preview)
  1. Download the crx or zip bundle.
  2. Open chrome://extensions.
  3. Enable Developer Mode (top right).
  4. Drag and drop the file to install.

​
💻 The Side Panel Interface

Click the Trace icon on your toolbar to open the Side Panel.

​
1. Chat & AI Assistant

The core interface is a chat window. You can speak naturally or use commands.
  • Context Aware: The AI knows the current URL, Console Errors, and Network status.
  • Slash Commands:
    • /debug: Run a full page diagnostic.
    • /network: Analyze recent XHR/Fetch requests.
    • /console: Summarize error logs.
    • /dom: Analyze the current page structure.

​
2. Session Recording (RRWeb)

Trace can record your entire browsing session—mouse movements, DOM changes, and clicks—to help reproduce bugs.
  • Start: Click the Record button.
  • Stop: Click Stop & Save.
  • Replay: Watch the session back pixel-perfectly with Session Replay.

​
3. Quick Actions (Chips)

One-tap access to common tasks:
  • Find Errors: Instantly scans the console for exceptions.
  • Performance: Checks Core Web Vitals (LCP, CLS).
  • Debug Page: Runs the standard diagnostic workflow.

​
⚙️ Settings

Click the Gear Icon to configure:
  • API Key: Connect your Trace Cloud account (required for AI analysis).
  • Power Mode: Allow the extension to modify the page (auto-fix capability).

​
🔌 IDE Bridge

The extension can connect to your local VS Code / Cursor instance via trace connect.
  1. Click Connect IDE in the top bar.
  2. When connected, clicking an element in the browser will open the corresponding source file in your editor.

🛠️ Troubleshooting

  • “No page connected”: Ensure you are on an active tab (not a chrome:// page). Refresh the tab.
  • “Network not captured”: Open the Side Panel before reloading the page to capture initialization requests.
