Evidence another party can check, for files and for agents.
Six products, each with its state today. Verify files free in the browser, protect files on Windows, validate Content Credentials from a paid browser account or your own code, and bring agent actions under the same kind of evidence.
Verify
Check a file online at no cost. Free Verify detects whether it carries Content Credentials (C2PA) and reports present — not evaluated, none detected, or not checked, and whether its exact bytes match a signed ChaosMark record. Full validation is a separate, paid hosted evaluation. JPG and PNG photos up to 1 MB.
Local Agent
Create signed evidence for a file with Protect and check it later with Verify, on your own Windows computer, including offline.
ChaosMark Validate
Full hosted evaluation of signatures, bindings, trust and ingredients for JPEG, PNG, WebP, MP3, WAV, M4A and MP4, at 2 Evidence Units per report. Upload from the paid account without an API key or use the same pipeline from your server. Each report names the validator build and records the findings your team can review.
Developer API
One authenticated endpoint for the same seven-format C2PA validation, with idempotency keys, retry rules that never bill twice, and Evidence Units on every response.
Recognition
When a JPEG or PNG has lost its credentials, find out whether it is still exactly a file you registered, by its bytes or its decoded pixels. Four answers, never a score.
Agent Evidence
One portable package, checked offline: what an agent was authorized to do, the specific action it took, and what a separate observer found at the destination. It is not available through the hosted browser or API.
Paid plan: online subscription appears only when the signed-billing and account service is ready; otherwise contact ChaosMark for activation. Enterprise evaluation: delivered in a scoped engagement with you, not as a hosted product.

Create demo
A walkthrough of how evidence creation works. It does not upload your file or produce a signed record; to create real evidence, use the Windows Local Agent.
Enterprise
Higher-consequence evidence workflows, integrations and private deployments, scoped with you against acceptance tests.
