Overview

Console Copy is a powerful developer toolkit that captures, analyzes, and exports browser console logs — with on-device AI (Chrome's built-in Gemini Nano) and a Lighthouse-style Page Analysis built in.

🚀 Headline features

✨ AI Assistant
On-device log analysis via Chrome's Prompt API. Pinpoints root cause, drafts ready-to-paste Jira/Linear/GitHub tickets, explains errors in plain language, and finds related logs. 65+ output languages, fully editable system prompt. No data leaves your device.

🛠 Page Analysis (New!)
One-click Lighthouse-style audit of the current page:
- Core Web Vitals: LCP, FCP, CLS, INP, TBT, TTFB
- Resource & request breakdown with waterfall
- Technology fingerprinting — frameworks, CMS, analytics, CDN
- SEO, Accessibility, Security headers checks
- AI-prioritized recommendations
- History & comparison between runs
- Optional Deep Analysis attaches Chrome's debugger to surface unused-CSS bytes and site storage usage

📡 Real-time capture
Logs, errors, warnings, network failures, uncaught exceptions, and promise rejections — intercepted from document_start. Repeated messages collapse with a counter badge.

🔔 Toast notifications
Configurable on-page alerts for new logs with one-click AI analysis straight from the toast.

🎯 Filter & search
Per-type filters, case-sensitive search, keyboard navigation through matches (Enter / Shift+Enter).

📤 Export
Copy filtered logs as Plain Text, JSON, or Markdown — ready to paste into bug reports, docs, or chat.

🛠 DevTools integration
Full-featured DevTools panel + browser-action popup; both surfaces share state and AI conversation.

🎨 UX
Auto light/dark theme matching DevTools, full context menu (copy / delete / AI actions per log row).

⚡ Performance
Per-tab log limit (100–50,000 entries) with IndexedDB for large buffers; renders thousands of rows smoothly.

🔒 Privacy first
Everything runs locally in your browser. AI inferences, page snapshots, and settings stay on your device — no telemetry, no servers, no tracking.

📖 Quick start
1. Click the extension icon, or open DevTools (F12) → "Console Copy" tab
2. Click 🛠 in the toolbar to run Page Analysis, or ✨ on any log row to ask the AI Assistant
3. Use filters, search, and export to share findings
