Free AI image and video verification

Free AI Image & Video Detector — check C2PA, metadata and watermarks

Drop an original image or video. AICheck365 reads verifiable file evidence—Content Credentials, metadata, generation parameters, container fields, and surviving watermark clues—without uploading the file.

Evidence, not a mystery scoreSee the exact field and source for every match
Best with original filesScreenshots and social downloads often lose provenance

Important: file evidence can be removed by screenshots, re-exports, editing apps, messaging services, and social-media transcoding. No signal found is not the same as “not AI-generated.”

What this detector can—and cannot—tell you

A valid C2PA manifest that declares trained algorithmic media is strong provenance evidence. EXIF/XMP software fields, PNG workflows, file names, and visual watermarks are supporting clues that can be edited or removed. An empty result means this copy has no readable evidence; it does not prove the media is human-made.

Why evidence disappears

Each share, compression, or screenshot may erase AI-origin signals.

Original platform file Intact

All metadata intact: C2PA, XMP, EXIF, PNG text chunks, generation params
Chat app transfer (WeChat / Telegram) Lost

Lost: PNG text chunks, most XMP fields, EXIF GPS data
Social platform transcode (Weibo / Twitter / Instagram) Lost

Lost: All EXIF fields, C2PA Manifest, XMP CreatorTool, all generation params
Screenshot or screen recording Lost

Lost: All original metadata; only screenshot tool EXIF remains
Re-export / save-as Lost

Lost: All provenance fields; new software may write unrelated EXIF

No signals found does not mean it is not AI-generated. Evidence may have been erased during sharing.

Methodology & Limitations

We can check

File metadata (EXIF / XMP / IPTC)
Provenance credentials (C2PA / Content Credentials)
Digital signatures and hashes
Platform marks and generation parameters
Container structure and file headers
Some edit and export clues
PNG text chunks
MP4/MOV container metadata and SEI markers

We cannot guarantee

All AI files retain provenance data
Screenshots retain origin information
All platforms use uniform marks
No signal means human-made
Results replace legal or expert appraisal

Evidence beats intuition. Transparency beats percentages.

Adobe Firefly image with valid Content Credentials Adobe Firefly

JPEG Unprocessed 2026-06-19

Source: Content Authenticity Initiative example assets (contentauth/example-assets, MIT)

1 signals: C2PA

Known limits:
digitalSourceType = trainedAlgorithmicMedia and the signature is cryptographically valid.
The signing certificate is not in this engine's trust list (untrusted), so the result is reported as 'valid' rather than 'trusted'.

AI-generated video with valid Google C2PA Content Credentials Google Veo

MP4 Unprocessed 2026-06-19

Source: User-provided original video carrying intact C2PA (Google generative-AI provenance)

2 signals: C2PA (Google Generative AI), MP4 encoding tool: Google

Known limits:
digitalSourceType = trainedAlgorithmicMedia (fully AI-generated); the BMFF C2PA manifest records 'Created by Google Generative AI' plus an imperceptible SynthID watermark, and the signature is cryptographically valid.
The manifest identifies 'Google Generative AI' (Veo is Google's video model); the signing certificate (Google LLC) is not in this engine's trust list, so the result is reported as 'valid' rather than 'trusted'.

OpenAI image whose C2PA certificate has expired OpenAI (ChatGPT / DALL·E)

PNG Unprocessed 2026-06-19

Source: Content Authenticity Initiative example assets (contentauth/example-assets, MIT)

1 signals: C2PA

Known limits:
A C2PA claim marked trainedAlgorithmicMedia is present, but the signing certificate is expired and untrusted.
Validation therefore fails: the provenance claim exists but cannot be verified (evidence state D).

Stable Diffusion XL output with embedded generation parameters ComfyUI / Stable Diffusion XL

PNG Unprocessed 2026-06-19

Source: ComfyUI official examples (comfyanonymous/ComfyUI_examples)

1 signals: PNG text chunks (prompt / workflow)

Known limits:
No cryptographic signature: only unsigned generation parameters embedded in PNG tEXt chunks.
Such chunks are routinely stripped by chat apps, social platforms, and screenshots.

Image with no provenance metadata —

JPEG Unprocessed 2026-06-19

Source: C2PA Rust SDK conformance fixtures (contentauth/c2pa-rs, Apache-2.0 / MIT)

Known limits:
No origin signals were found. This is not proof of human creation.
Evidence may have been removed earlier in the file's distribution chain.

Plain photograph, no embedded provenance —

JPEG Unprocessed 2026-06-19

Source: NASA (public domain), via contentauth/c2pa-rs fixtures

Known limits:
No AI or provenance signals detected.
Absence of signals cannot distinguish a real photo from an AI image whose evidence was stripped.

Tampered C2PA signature (content hash mismatch) C2PA test sample (tampered)

JPEG Processed 2026-06-19

Source: C2PA Rust SDK conformance fixtures (contentauth/c2pa-rs, Apache-2.0 / MIT)

Known limits:
A C2PA manifest is present but the asset hash does not match (assertion.dataHash.mismatch) and the certificate is untrusted.
The provenance claim is therefore invalid (evidence state D).
