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
Qausal is a web-based electronic-signature platform for preparing and verifying signed PDF documents. Users can upload a PDF, invite one or more signers, assign signing roles and sequence, and track signature progress; invitees can sign without creating an account. Qausal uses ML-DSA-65, the post-quantum digital-signature algorithm standardized as FIPS 204, to create signatures intended to remain verifiable against future quantum-computing risks. Signature data, public keys, and digests are embedded in the signed PDF, and users can download a proof bundle for independent offline verification with open-source tools. Qausal also supports adding a quantum-safe attestation to documents signed through other services without altering the original document. It is intended for organizations that need durable verification of agreements and records, including legal, financial, healthcare, and government-related workflows.
