About

ProofSign is an electronic-signature and document-verification platform for individuals, professionals, teams and organizations signing finished PDFs. Users upload documents, invite signers and approvers, and run single- or multi-party workflows. Participants verify email access with a one-time passcode. ProofSign records signing intent, participant actions and timestamps in an audit trail. Completed PDFs include a SHA-256 fingerprint and evidence recipients can check through a public verifier without an account. The service supports agreements and finalized documents that need an auditable signing record and a way to detect later file changes. Its free plan allows single-party signing and verification for up to 10 documents monthly under fair use. Users can earn credits through onboarding and signing milestones. The Pro plan includes a verification API.

About

Truthlocks helps individuals, businesses, and developers create and verify signed digital evidence. Proof Frame turns public statements into shareable proof pages with live verification and local file comparison. APIs and SDKs support record verification, machine identity, and signed AI action receipts. Signature validity, issuer assurance, revocation, and transparency evidence are separate checks; a valid signature does not establish that a claim is factually true. The hosted platform is proprietary, and public integrations have separate licenses. Organizations can issue signed records through hosted workflows, with operations billed by usage.
