Auditability
Each signing event is linked into a SHA-256 audit chain and completion certificate.
AI signer support
Document-grounded Q&A helps signers understand what they are reviewing before they sign.
Open source
The AGPL-licensed codebase can be inspected, self-hosted, and adapted by technical teams.
Operator accountability
Published ownership, terms, and privacy policy keep the service accountable.
Integration readiness
REST APIs, HMAC-signed webhooks, and embeddable forms connect signing with the tools your business already uses.
Independent verification
Check a signed document without asking anyone for access.
Upload the completion certificate, and optionally the signed PDF. UniSi checks the platform signature and whether the document still matches the audit trail.
