Send it. Sign it.
Prove it.

DigiSign turns any document into a signable agreement — drag the fields where they belong, send it off, and get back a signed PDF with a certificate that stands up to scrutiny.

Place fields exactly

Drag signatures, initials, dates, text boxes and checkboxes onto any page and assign each one to a specific recipient. Nobody sees fields that are not theirs to complete.

Sign in order, or all at once

Route a document through a chain of approvers step by step, or send it to everyone simultaneously. Add an access code where a link alone is not enough.

Prove what happened

Every open, signature and decline is hash-chained with SHA-256. The certificate of completion is generated from that log, so it can never disagree with it.
