Deepfake probability

Deepfake is a separate face-manipulation signal; it does not by itself mean the whole image is AI-generated.
AI watermark checks are strongest when they find signed provenance or a provider watermark. Missing signals do not prove the image is human-made or unedited.
How to read the result
0%–30% No strong AI signal; real photos and ordinary screenshots often fall here.
31%–89% Inconclusive; compression, redraws, AI edits, reposted screenshots, and mixed editing appear here more often.
90%–100% The pixel model found a strong AI signal.
100% Verified AI Not a Hive model probability; trusted signed provenance directly confirms the AI origin.

Informational only; not an AI classifier What this AI watermark checker covers
AI watermark queries are different from generic AI detector queries. Searchers want to know whether a file contains durable provenance evidence, not just whether it looks generated.

Invisible watermarks
Explains provider-specific watermarks and routes SynthID checks to Google’s official verifier instead of inventing a result from a general vision model.
Content Credentials
Reads C2PA locally before upload so signed provenance can be surfaced early in the review.
Metadata context
Adds file type, dimensions, and other basic details that help reviewers understand the evidence.
AI watermark types compared
Different tools use different trust signals. A good AI watermark checker separates invisible marks, signed provenance, visible labels, and ordinary metadata instead of collapsing them into one score.
Signal type
Best use
Weakness
Invisible watermark
Provider-specific evidence such as SynthID when supported.
Coverage depends on the generator and may degrade after edits.
C2PA credential
Signed origin, editing history, tool names, and AI-use declarations.
Can be stripped by platforms, screenshots, or file conversion.
Visible label
Fast human review when a platform visibly marks generated media.
Easy to crop, cover, remove, or fake.
Basic metadata
File format, dimensions, size, and limited tool context.
Useful context, but not reliable proof by itself.
AI watermark signal hierarchy
The practical rule is simple: a verified signal matters more than a visual guess. Missing evidence should be treated as inconclusive, especially for legal, editorial, moderation, or brand-safety decisions.
Strong
A watermark confirmed by its official provider verifier, or valid signed provenance that explicitly declares AI use.
Useful
Valid claim-generator data and explicit AI-use assertions inside a readable C2PA manifest.
Weak
Generic classifier scores or ordinary metadata that can help triage but should not be treated as proof.
Missing
No signal found means the checker found no supported evidence. It does not certify the image as real.
When to use an AI watermark detector
Watermark and provenance checks are best for workflows that need a defensible evidence trail.
Editorial verification
Check whether a submitted image carries AI provenance before using it in reporting or publishing.
Marketplace review
Triage product, avatar, or listing images where synthetic media disclosure matters.
Brand safety
Review influencer, ad, and user-generated creative before approval or escalation.
Moderation queues
Use strong signals to prioritize manual review without over-trusting generic AI classifier scores.

AI watermark checker FAQ
How to read watermark, C2PA, SynthID, and metadata results.
This page validates local C2PA provenance and explains provider watermarks. It does not claim to detect private SynthID or Meta watermarks automatically; those require an official provider verifier.
No. A watermark is embedded into the generated media itself, while metadata is file information that can describe origin or edits. Metadata is usually easier to remove.
No. If no watermark or provenance signal is found, the result is inconclusive. The file may still be AI-generated by an unsupported model or may have lost evidence during editing.
C2PA can provide signed provenance locally, while SynthID requires Google’s official verification flow. Keeping the results separate prevents a general AI probability from being mistaken for a watermark.
