AI Analyzers
AI Image Detector
Upload a photo or paste a URL to check its provenance. The detector verifies signed Content Credentials, combines semantic and low-level learned models, and reports Uncertain when the evidence is outside its calibrated operating range.
Free to use, no sign-up required. Your images are processed in-memory and never stored.

How AI Image Detection Works
Metadata Inspection
Cryptographically verifies Content Credentials. Unsigned EXIF and software fields are displayed as forgeable context, never as proof.
Semantic Model
A frozen vision encoder evaluates the complete image and spatial crops for generator-independent learned evidence.
Pixel-level Expert
A separately trained model analyzes multiscale spectral and neighboring-pixel representations without treating compression as proof.
Calibrated Decision
A learned fusion model uses error-controlled thresholds, detects distribution shift, and abstains instead of forcing a binary answer.
