Support & Help Center

How do I install the extension?

1. Visit the Chrome Web Store listing for AI Image Signal Analyzer

2. Click "Add to Chrome"

3. Confirm the installation when prompted

4. The extension icon will appear in your browser toolbar

How do I analyze an image?

Method 1: Right-Click (Recommended)

• Right-click on any image on a webpage
• Select "Analyze Image" from the context menu
• Results appear automatically in the popup

Method 2: Upload Local Files

• Click the extension icon in your toolbar
• Drag and drop images or click to browse
• Upload single images or multiple for batch analysis

What image formats are supported?

The extension supports the following formats:

• JPEG/JPG - Most common format
• PNG - Lossless format with transparency
• WebP - Modern web format

Requirements:

• Minimum size: 128×128 pixels
• Maximum file size: 10MB per image

What is the Heatmap Visualization?

The heatmap feature provides a visual overlay on your analyzed image showing suspicious regions:

• Red overlay indicates areas with high AI generation suspicion
• Darker red = higher suspicion level
• Toggle on/off using the "Show Heatmap" button
• Helps identify specific areas of concern in the image

How does Batch Analysis work?

Batch analysis allows you to process multiple images at once:

• Upload 2-10 images simultaneously
• Real-time progress tracking shows processing status
• All results automatically saved to history
• View summary statistics after completion
• Perfect for bulk verification tasks

How do I use the Analysis History?

The history feature tracks all your past analyses:

• Click the "History" button in the popup
• View statistics dashboard (Total, AI, Real, Uncertain)
• See thumbnail previews of analyzed images
• Click any item to view full analysis results
• Delete individual items or clear all history
• Stores up to 50 most recent analyses

Can I export analysis results?

Yes! The extension offers two export options:

• PDF Export: Download professional analysis reports with all details, charts, and signal breakdowns
• Share Report: Copy formatted text report to clipboard for easy sharing

What are the 10 Detection Signals?

Each image is analyzed using 10 sophisticated detection methods:

How do I interpret the AI Probability score?

The AI Probability is a percentage (0-100%) indicating the likelihood of AI generation:

• 65-100% (Likely AI) - High confidence the image is AI-generated
• 35-65% (Uncertain) - Mixed signals, inconclusive
• 0-35% (Likely Real) - High confidence the image is real/authentic

Important: This is a probabilistic estimate, not a definitive verdict. Always combine with other verification methods.

What do the confidence levels mean?

Each detection signal shows a confidence percentage:

• High (70-100%): Strong indicator of AI generation
• Medium (40-69%): Moderate indicator
• Low (0-39%): Weak or no indication

Can the extension be wrong?

Yes. The extension provides probabilistic estimates based on signal analysis. Factors that can affect accuracy:

• Heavy image editing or compression
• Very small images (< 512px)
• Screenshots or re-saved images
• New AI generation techniques
• Artistic filters or effects

Best Practice: Use results as one factor in your verification process, not as sole evidence.

Is my data safe?

Yes, absolutely. AI Image Signal Analyzer is designed with privacy as a top priority:

• All analysis happens locally in your browser
• No images are uploaded to any server
• No personal data is collected
• No tracking or analytics
• History stored locally on your device only

What permissions does the extension need?

The extension requests minimal permissions:

• activeTab: Access images on the current tab for analysis
• contextMenus: Add "Analyze Image" to right-click menu
• storage: Store analysis history locally
• host_permissions: Access images from any website (local processing only)

Despite broad permissions, no data leaves your device.

Can I delete my analysis history?

Yes! You have full control over your data:

• Delete individual history items by clicking the delete button
• Clear all history using the "Clear All History" button
• Uninstalling the extension removes all stored data

🎓 Best Practices

Tips for getting the best results:

• Upload original, unedited images when possible
• Larger images (> 512px) provide more accurate results
• Use batch analysis for multiple images
• Check heatmap for visual confirmation
• Review history to track patterns
• Combine with other verification methods
• Multiple high-confidence signals = higher reliability
