How AI Image Detector works
Every scan runs five independent forensic techniques and merges them into a single, easy-to-read verdict. No single signal decides the outcome.
1. Error Level Analysis (ELA)
We re-compress the image and measure where it changes the most. Edited regions often compress differently from the rest of the photo and "light up" in the ELA heatmap you can explore with the before/after slider.
2. Metadata (EXIF)
We inspect embedded metadata for editing-software signatures such as Photoshop or Lightroom - a supporting hint, not proof on its own.
3. Machine-learning models
Two trained models analyse texture patterns and vote on whether the image looks authentic or synthetic/edited. Additional weighted datasets refine the decision.
4. Frequency-domain AI analysis
AI generators leave subtle traces in the frequency domain - overly uniform noise, unusual channel correlations, and smooth textures. We score four such signals.
5. Content Credentials (C2PA)
If an image carries signed provenance metadata declaring it was made or edited by a generative-AI tool, we read and surface that.
