About AI Media Checker

What is AI Media Checker?

AI Media Checker is a browser-based forensic tool that analyzes images for AI-related evidence. Unlike binary "AI or Not" detectors, we provide a transparent, explainable evidence report.

All analysis happens locally in your browser. Your images never leave your device.

  • No cookies or tracking
  • No data collection
  • No third-party API calls
  • Open source approach (planned)

πŸ”¬ Our Approach

We combine three evidence types:

  1. File Evidence: EXIF, XMP, PNG metadata
  2. AI Signatures: Prompts, models, seeds, workflow traces
  3. Pixel Forensics: Frequency patterns, noise analysis (auxiliary signals)

Results are presented as evidence strength, not binary classification.

⚠️ Limitations

  • Results are not proof of AI generation
  • Pixel forensics are statistical indicators only
  • Metadata can be stripped, edited, or faked
  • Some AI tools leave no detectable traces
  • Compression and editing affect pixel signals
  • False positives and negatives are possible

πŸ“Š Technology

  • Frontend: Astro, TypeScript
  • Metadata: ExifR library
  • Forensics: Custom FFT-like frequency analysis
  • Workers: Web Workers for non-blocking pixel analysis
  • Deployment: Cloudflare Pages (static)
