C2PA Signer provides local-first tools for working with C2PA Content Credentials. The free Chrome extension helps users verify files, scan web pages and test-sign media directly in the browser. ProvSeal Enterprise extends this workflow into on-premise organizational environments with a desktop app for local signing, verification and batch processing, hardware/HSM-ready signing workflows, and an Enterprise Console for managing machines, policies, audit metadata and releases.
The product reviews provenance and integrity signals. It is not fake detection and does not prove that content is true or false.
