Sealmatter, the identity-swapping membrane for confidential AI work
Sealmatter describes a layer that replaces names, numbers, and addresses with consistent stand-ins before confidential documents reach external AI tools, then restores identities inside the customer’s environment.
Field notes
The proposed workflow accepts files, forwarded email, or a connected folder, then replaces identities with stable stand-ins before sending documents to an AI system. Returned drafts are re-identified inside the customer’s environment, with a restoration count attached. The page names legal, HR, and insurance use cases and describes a second AI risk check followed by one named human signature. Deployment is presented as available through an EU cloud, the customer’s cloud, or fully inside its walls.
