Sigil
Signatures you can trust.

Send, seal, and prove documents. Get proof anyone can check.

Collect signatures on contracts, issue personalized PDFs from your organization, and give recipients independent verification that a file is authentic and unchanged.

Signature request

One document, one or a few signers—contracts, NDAs, offer letters.

Campaign

The same document to many people—each gets their own signing link.

Issuance

Many personalized PDFs signed by your team; recipients receive their copy.

Built for real paperwork

Whether you are a freelancer sending a contract, an HR team collecting offer signatures, issuing training credentials, compliance reports, or uptime attestations—Sigil keeps each flow clear, with a tamper-evident record and public verification anyone can check.

Early access preview. Not yet intended for regulated or high-stakes legal workflows without your own review.
