Sample screen
How it works
Three steps. No account for the signer.
Upload & place fields
Drop a PDF or scan paper with the iPhone. Drag signature, initials, date, name and text fields onto any page — each signer gets their own color.
Choose how each person signs
Email, WhatsApp, text, a link — or a recorded phone call where an AI attendant reads a summary and the signer says “I agree” with their full name.
Sealed and saved
When the last person signs, the PDF gets a certificate page, a SHA-256 seal and an RFC 3161 timestamp, and is saved to your DOCZ.
Every channel your customer uses
They don’t open your email? Text them. Or call.
Pick one channel per signer. Every channel opens the same personal signing link — except the phone call, where the signature is the signer’s own voice on a recorded line, with a live transcript on your screen.
- Remind in one click; a new link replaces the old one
- Sign in order or all at once
- Optional identity check before signing (driver license + selfie)
- Optional printed copy by USPS Certified Mail — PostKite, $11.95
From your company name, with the document title.
The invite where your customer already talks to you.
Text (SMS)
A short message with the personal link.
Link or your own site
Copy the link, or put our sign button on your site.
Phone call — sign by voice
AI VOICE“This call is recorded.” The attendant confirms who is speaking, reads a short summary and asks for “I agree” with the full name. The recording and the transcript go into the certificate.
Evidence, not promises
Every signed PDF carries its own proof.
Signer timeline
Invited, opened and signed — with time, channel and method for each person.
IP address and time
Recorded at the moment of signing and printed on the certificate.
SHA-256 seal
A hash of the final PDF; any change after sealing is detectable.
RFC 3161 timestamp
A trusted timestamp of the seal from an independent time authority.
Certificate page
Attached to the PDF: who signed, when, how, and the seal.
Saved to DOCZ
The sealed PDF lands in your team’s document vault, searchable.
