Leonardo.Ai image detector: what the file can prove

Leonardo.Ai publishes no provenance documentation we could find as of October 2026, so an image from it is identified only by whatever records the download carries, and isGenAI lists each of those records with its source field.

Facts checked against vendor documentation in October 2026. Updated .

AI source type declared

The file labels itself as AI-made.

IPTC DigitalSourceType such as trainedAlgorithmicMedia is read from XMP and shown with its exact value.

Verified and unverified

We found no Leonardo.Ai statement on C2PA Content Credentials, IPTC DigitalSourceType or prompt metadata in exported images as of October 2026. Leonardo runs a range of models, including Stable Diffusion derivatives, but a hosted service decides what reaches the download, and that decision is not documented.

Treat every Leonardo export as unknown until inspected. The cost of inspecting is one upload.

What isGenAI reports

The checker validates any signed manifest, reads IPTC source types from XMP, quotes AI statements found in metadata, reads AUTOMATIC1111, ComfyUI and InvokeAI prompt records and checks the hash and fingerprint against known copies. Findings are listed under “How we checked” with their field names.

A file with nothing readable returns “no evidence found”. The report never substitutes a pixel-based guess for missing records.

Getting a checkable copy

Download from the Leonardo library rather than saving a preview, and avoid passing the file through messaging apps that re-encode images. For an image found online, trace the first upload and download from there.

If an earlier copy carried metadata, the matching-copy check can connect a stripped repost to it.

Leonardo also offers image-to-image and canvas editing. An edited export is a new file, so check the version you were actually sent, not an earlier generation from the same session.

How to check an image from this generator

  1. Get the original download, not a screenshot or a copy saved from a chat or social feed.
  2. Upload it to the free AI image detector. Files up to 20 MiB in PNG, JPEG, WebP, AVIF or TIFF are read on the server and are private by default.
  3. Open “How we checked” and read each finding with its source field: signed record, declared source type, saved prompt, AI statement or matching copy.
  4. Treat a clean result as “no evidence found”, never as proof that a person made the picture.

Frequently asked questions

Does Leonardo.Ai add metadata to images?

We found no vendor documentation as of October 2026. Upload the original download; isGenAI reports any C2PA record, source type, AI statement or saved prompt it actually contains.

Can isGenAI detect a Leonardo image after a screenshot?

No. A screenshot carries no file records and isGenAI does not infer origin from pixels. The original export is the file to check.

What if the report says no evidence found?

It means the file holds none of the records isGenAI reads. That is an absence of evidence, not proof that a person made the image.

Which isGenAI tool shows every raw field?

The EXIF viewer lists the readable fields in the browser; the AI image detector interprets them into an evidence report.
