Truthlocks provides cryptographic trust infrastructure for digital records, signed statements and AI agent actions. Individuals and organizations can publish signed text with explicit disclosure controls, share public proof links and check whether presented content matches the signed evidence. Proof Frame supports an editable demonstration copy without changing the original signed record, and linked revisions retain the relationship between statement versions. Businesses use a workspace console; developers integrate supported APIs, SDKs and MAIP integrations for machine identity and signed action receipts. Public proof pages distinguish content integrity, digital signatures, issuer assurance and available status and transparency evidence. A self-registered issuer is not independently accredited, and a valid signature is not proof that the underlying statement is true. The hosted platform is proprietary. Public SDKs and integrations have their own repository licenses. A recipient can open an intentionally public proof without creating an account. Eligible public text records include a separate editable demonstration copy: changing a character tests the content fingerprint while leaving the original signed statement intact. The interface explains what was signed, which checks completed and what evidence remains unavailable. This makes the workflow useful for public announcements, professional declarations and technical records. Signing a revised statement creates a linked version instead of silently overwriting the original. For teams integrating the product, documentation and public examples provide a starting point for evaluating the supported record and receipt workflows. Issuance follows account permissions, onboarding requirements and applicable usage allowances. Organizational operations are metered; personal plans and allowances are separate. The public website links to current pricing and a reproducible technical evidence page.
