Pixel Proof por Arthur

Image authenticity & AI detection tool - 100% local, privacy-first

Pixel Proof helps you verify image authenticity by detecting AI-generated content, analyzing metadata, and identifying manipulation. All analysis runs locally in your browser - no data is ever sent to external servers.

Features

• AI/Synthetic Detection - Pattern analysis to identify AI-generated images (Midjourney, DALL-E, Stable Diffusion, etc.)
• Error Level Analysis (ELA) - Detect edited/manipulated regions in photos
• Metadata Extraction - View EXIF, XMP, IPTC data including camera info, GPS, and AI generation parameters
• Trust Score - Combined confidence score based on multiple analysis factors
• Reverse Image Search - Quick links to Google, Bing, TinEye, Yandex image search
• Content Credentials (C2PA) - Verify authenticated content provenance
• Export Reports - Save analysis as JSON, HTML, or PDF
• Analysis History - Browse and search previous analyses

Privacy

Your privacy is guaranteed. Pixel Proof performs all image analysis locally using your browser's computing power. No images or data are uploaded to any server. The only network requests are for optional reverse image search (which opens in a new tab)

Detection Methods

Analyzes image patterns commonly found in AI-generated content:
- Frequency domain artifacts
- Noise pattern analysis
- Gradient smoothness detection
- Upsampling artifact detection
- Metadata signatures from known AI tools

Error Level Analysis (ELA)
Recompresses the image and highlights areas with different compression levels, which can indicate editing or splicing

Trust Score
Combines multiple signals into a single confidence score:
- AI detection patterns
- Metadata completeness
- Content credentials
- Source verification
