Free AI Content Credentials checker
Drop in an image or PDF and read its C2PA Content Credentials: whether it was made or edited with AI, which tool signed it, its edit history, and whether the signature still validates. The check runs entirely in your browser — the file never leaves your device.
What does this image actually say about where it came from?
C2PA Content Credentials are a tamper-evident manifest that tools like Adobe Firefly, Photoshop, some cameras, and a growing list of AI generators sign into a file. Drop a file in and read what it declares — the check runs on your device, so the file is never uploaded.
or drag & drop a JPG, PNG, or PDF here. Nothing is uploaded — the check runs in your browser.
No file checked yet
Choose a file to read its Content Credentials. Most images on the web carry none at all — that is normal and does not mean a file is fake or real.
Claude AI text-watermark detection
Anthropic began watermarking all Claude output in August 2026, but has not yet published the detection specification — so nobody can truthfully decode that text watermark today. We are not going to ship a fake detector. The moment Anthropic releases the spec, this checker gains a paste-your-text detection mode. Until then, this space is honest about what cannot yet be done.
Provenance is one signal in a much bigger picture. Orchory turns your business profile into a ranked queue of pages worth building — each with the content, metadata and structured data your coding agent ships. Explore the rest of the free tools while you are here.
Start freeFrom a file to its provenance in three steps
No account, nothing to install, and no upload. Pick a file and read what its Content Credentials declare.
Choose a file
Drag in a JPG, PNG, or PDF, or click to pick one. The file is read locally in your browser using the open C2PA wasm toolkit — nothing is uploaded and nothing is stored.
We read the manifest
If the file carries a C2PA manifest, we parse the signed provenance: the signing tool, edit actions, timestamp, and whether the signature validates against the embedded certificate.
Read the provenance
You see a plain-English verdict: AI-generated or not, who signed it, what was done to it, and whether the credential is still intact. No manifest? We say so honestly, without guessing.
Who checks Content Credentials
Anyone who needs to know whether a file carries verifiable provenance — and what that provenance actually claims — before they trust or publish it.
Journalists & fact-checkers
Verify whether a viral image carries provenance from a camera or a generative tool before you publish, and see whether it was edited after signing.
Trust & safety teams
Triage user-submitted media at a glance: read the declared source type and edit history instead of eyeballing pixels.
Designers & agencies
Confirm the Content Credentials on assets from Adobe Firefly, Photoshop, or a stock library survived your export pipeline.
Anyone handed an image
Answer one honest question — does this file say anything verifiable about where it came from? — without installing a toolchain.
What a Content Credential does — and does not — prove
C2PA is genuinely useful, but it is not a lie detector for images. Here is the honest version.
- It records processing, not authorship. A manifest says a file passed through a tool that signed it — not who made the underlying creative decisions.
- Absence proves nothing. Most files carry no credentials at all. A screenshot, a re-save, or a format conversion strips the manifest, so "no credentials" never means "human-made" or "fake".
- Presence is a claim, not a guarantee. A valid signature means the manifest has not been altered since signing and traces to a certificate — it does not independently verify the content is true.
- AI is declared, not detected. When we say "AI-generated", we are reading a flag the signing tool wrote into the manifest. We are not analysing pixels or running a classifier.
