PDF Software / E-Signature

PDF e-signature software with OTP verification and trusted timestamps.

Docuplete collects e-signatures as part of the form completion session — not as a separate step. The client fills the guided interview, reviews the completed document, and signs with OTP-verified identity. Every signed document receives an RFC 3161 trusted timestamp and a SHA-256 tamper-detection hash — on every plan.

Fit

Who it's built for.

Good fit when…

You need signer identity tied to a verifiable email address (OTP)
You need an independent trusted timestamp — not just a database record
You want form completion and signing in one client session
You work in regulated industries where audit trail quality matters
You need to verify signed documents after the fact by hash or token

Not the right tool when…

You need only a simple signature box with no identity verification
Your workflow requires wet (ink) signatures — Docuplete is electronic only
You need in-person signing in front of a notary — Docuplete is remote/digital
