The signature
of record.
SignFlowX sends offer letters, NDAs and contracts that people sign on their phone — sealed, tamper-evident, and legally binding, with a full certificate of record for every signature.
Built for compliance
A signer's bill of rights
Every person you send to is protected by these — by default.
Know before you sign
An AI summary explains the document in plain English — key terms and clauses to note — before anyone signs.
Only you can sign
Optional identity check: signers confirm their name (3 tries, then the link locks) before the document is even shown.
A permanent record
Every signature is sealed with a SHA-256 hash, Document ID, timestamp and IP — and a court-ready certificate.
Sign anywhere
Email, SMS or WhatsApp; sign on any phone with no app, account or password.
A complete signing platform
AI document intelligence
Plain-English summaries, key terms and risk flags on every document.
Add fields & text
Signature, date, initials and your own text anywhere on any PDF.
Bulk send
One document to hundreds — each individually tracked and sealed.
Sealed & verifiable
Tamper-evident PDFs with per-page Document ID and SHA-256.
Teams & roles
Organizations, sub-orgs, granular roles, IP allowlists and access passes.
Certificate of record
A clean, court-ready audit certificate accompanies every document.
