Comparison
Compare AI Watermark & Provenance Systems
This table compares documented implementation states for Claude, OpenAI, Gemini, and Adobe Firefly. It is not a ranking of strength, safety, or how hard a watermark is to remove.
| Dimension | Claude | OpenAI | Gemini | Adobe Firefly |
|---|---|---|---|---|
| Text watermark | Documented Documented statistical / SynthID-Text-derived for supported new models | Unknown Unknown — not established in reviewed documentation | Documented Documented SynthID for Gemini app and web text | Not applicable Not applicable (image product family) |
| Image watermark (SynthID or equivalent) | Unknown Unknown as a pixel watermark; text watermark is statistical | Documented Documented SynthID on supported generated images | Documented Documented SynthID, including Nano Banana outputs | Unknown Unknown — not established from Firefly documentation |
| Content Credentials / C2PA | Conditional / partial Documented on supported generated files (PNG/JPG/SVG) | Documented Documented on supported generated images | Conditional / partial Documented for Gemini Apps media, not every Google product | Documented Automatic credentials on 100% Firefly-generated assets |
| Video | Unknown Unknown | Unknown Unknown in current Help Center tables reviewed here | Documented Documented SynthID; Gemini can verify uploaded video | Unknown Unknown |
| Audio | Unknown Unknown | Documented Documented SynthID on supported generated audio | Conditional / partial Documented on specific Google audio/Gemini Apps surfaces | Unknown Unknown |
| Public verification | Unknown Text detector announced, not generally released here | Documented Public image and audio verifier plus documented Content Provenance API; not integrated here | Documented Gemini verifies Google AI image, video, audio — not all SynthID | Documented Adobe Inspect for Content Credentials |
| AI Watermark Center inspection | Conditional / partial Unicode + embedded JPEG/PNG/WebP C2PA; no statistical detector | Conditional / partial Embedded image C2PA only; no SynthID, no audio, no OpenAI API integration | Conditional / partial Embedded image C2PA only; no SynthID | Conditional / partial Embedded image C2PA; no Adobe cloud recovery |
On small screens the matrix scrolls horizontally. The first column stays in view so each dimension remains labelled.
AI Watermark Center capability
| Capability | Status | Notes |
|---|---|---|
| Text hidden-character inspection | Available | Deterministic Unicode inspection in the browser. |
| Image EXIF / metadata inspection | Available | EXIF and GPS fields for JPEG, PNG, and WebP. Missing metadata is not an origin verdict. |
| Embedded C2PA inspection for JPEG/PNG/WebP | Available | Embedded manifests only. No cloud recovery. |
| SynthID detection | Not available | Not implemented. Provider verifiers remain separate. |
| Statistical Claude text watermark detection | Not available | Requires Anthropic’s keyed detector, which is not integrated. |
| Visible watermark recognition | Not available | No automatic visible-mark classifier. Visible marks are documented from provider sources, not detected here. |
| Audio watermark inspection | Not available | No audio inspector. |
| Video watermark inspection | Not available | No video inspector. |
