Detect AI-Generated Websites & Vibecoded Sites
Vibe is a free Chrome extension that detects AI-generated websites and vibecoded sites by analyzing visual patterns, purple gradients, excessive emojis, and content markers. Identify websites created with minimal human input instantly. Get confidence scores and detailed pattern detection to spot AI-created content.
AI Website Detection Features
AI Website Confidence Scoring
Get a percentage-based confidence score indicating how likely a website is to be AI-generated or vibecoded, displayed in a clean circular meter. Instantly know if you're viewing an AI-created website.
Vibecoded Pattern Detection
Identifies multiple visual and content patterns that indicate AI-generated websites, including purple gradients, excessive emojis, generic taglines, AI-style code comments, and other vibecoded markers.
Detailed AI Detection Analysis
View specific detected patterns with explanations. Each pattern includes tooltips that explain why it's a sign of AI-generated content, helping you understand how the extension detects vibecoded websites.
Customizable Settings
Adjust detection sensitivity, configure badge display, set notification thresholds, and customize the verdict threshold to match your needs.
Smart Notifications
Receive browser notifications when high-confidence vibecoded sites are detected, with customizable threshold settings.
Keyboard Shortcuts
Quick access with keyboard shortcuts: R for reevaluate, T for theme toggle, and S for settings. Can be disabled in preferences.
How to Detect AI-Generated Websites
Automatic AI Website Analysis
The extension automatically analyzes pages as you browse, checking for visual patterns and content markers that indicate AI-generated websites or vibecoded sites.
Vibecoded Pattern Detection
Multiple detection algorithms scan for purple gradients, emoji usage, generic content, AI-style code comments, and other indicators of AI-generated websites.
AI Detection Calculation
Patterns are weighted and combined to generate a confidence score for detecting AI websites, with sensitivity modes (strict, normal, lenient) to reduce false positives.
Instant Visual Feedback
View results in the popup with a confidence meter showing the likelihood of an AI-generated website, verdict, and detailed list of detected vibecoded patterns.

Frequently Asked Questions
How do I detect AI-generated websites?
Vibe automatically detects AI-generated websites by analyzing visual patterns like purple/blue gradients, excessive emojis, generic taglines, AI-style code comments, and other content markers. The extension provides a confidence score indicating how likely a site is to be AI-generated or vibecoded.
What is a vibecoded website?
A vibecoded website is a site created with AI tools with minimal human input. These sites typically feature purple/blue gradients, excessive emojis (especially sparkles), generic taglines, AI-generated code comments, missing meta tags, and inconsistent styling patterns.
How accurate is AI website detection?
Vibe is pretty accurate, but can produce false positives and negatives. Generally, with more content, it will find more indications of vibe coding. The confidence score reflects the likelihood that a site is AI-generated based on detected patterns, and you can adjust the sensitivity mode to reduce false positives.
Can it give false positives when detecting AI websites?
Yes, false positives are possible. Some legitimate websites may share visual patterns with AI-generated sites. You can adjust the sensitivity mode in settings (strict, normal, or lenient) to reduce false positives. The lenient mode is recommended if you're seeing too many false positives.
How do I adjust the sensitivity?
Open the extension options page and navigate to "Detection Sensitivity". Choose between Strict (more aggressive detection), Normal (balanced), or Lenient (fewer false positives). You can also adjust the verdict threshold to control when a site is marked as "Vibecoded".
Does it work on all websites?
Vibe works on most websites, but cannot analyze Chrome internal pages (chrome://), extension pages, or some restricted sites. The extension automatically runs when you visit a page, and you can manually re-evaluate by clicking the refresh button in the popup.
Is my data sent anywhere?
No. All analysis happens locally in your browser. Vibe does not send any data to external servers. Your browsing history, analyzed pages, and settings are stored locally on your device using Chrome's storage API.
Is the extension free?
Yes, Vibe is completely free to use. There are no premium features, subscriptions, or hidden costs.
What patterns does it detect?
Vibe detects visual patterns like purple/blue gradients, excessive emojis, generic taglines, card layouts, and content markers such as AI-style code comments, missing meta tags, outdated copyright years, and inconsistent styling patterns.
Can I disable keyboard shortcuts?
Yes. Go to the extension options page and uncheck "Enable keyboard shortcuts" in the Keyboard Shortcuts section. This will disable the R, T, and S shortcuts in the popup.
