NovelAI Image Checker — Detect NovelAI Generated Images

How to use

Drop the image
Drag a PNG, JPEG, or WebP file into the drop zone. Processing runs entirely in your browser.
Read the detection report
The inspector checks for C2PA Content Credentials and EXIF metadata that NovelAI embeds in its generated images.
Understand the verdict
A positive match means the image carries NovelAI-specific fingerprints and was likely generated by NovelAI.

Drop the image into the AI Image Inspector on this page. It checks for C2PA Content Credentials and EXIF tags associated with NovelAI.

Yes. NovelAI embeds C2PA Content Credentials and EXIF metadata in its generated images for provenance tracking.

PNG, JPEG, and WebP files are supported. Processing is 100% local — no upload, no server.

Structural detection, not pixel-levelThe inspector reads C2PA manifests and EXIF tags. It does not run a neural classifier on the pixels. A NovelAI image that has been re-encoded with all metadata stripped will be reported as 'No AI generation traces found.'
Screenshots defeat detectionTaking a screenshot of a NovelAI image strips the C2PA manifest and metadata block during re-encoding. The screenshot will read as 'No AI generation traces found.'
PNG, JPEG, and WebP onlyThe C2PA chunk reader works on PNG iTXt/zTXt, JPEG APP11 JUMBF, and WebP 'EXIF' chunks. AVIF, HEIC, and TIFF are not decoded.

macOS: Preview.app and Quick Look do not surface C2PA Content Credentials. The inspector is the right tool for diagnosing NovelAI provenance from any source.
Windows: Windows Photos and File Explorer show EXIF but not C2PA. For full provenance, drop the file into the inspector.
Linux: `exiftool -api RequestAll=3 image.png` shows C2PA claim chains and XMP. The inspector is the right pick when you want a single report covering every NovelAI fingerprint.
Web: Runs entirely client-side. The image is read as a Uint8Array; all detectors run as pure JavaScript. No upload, no server roundtrip, no telemetry.
