Send in minutes. Sign from any device. Verify any time.
Chasing signatures shouldn't mean printing, scanning, and hoping someone checks their inbox. XOsign sends agreements for signature in minutes, lets every party sign from any device — by email, SMS, or in person — and keeps a verifiable record of exactly who signed what, and when.
AI-assisted document tools — not legal advice.
Understand. Improve. Sign.
Signing is the last act of the XOsign story — and it goes smoothly because everything before it made the agreement worth signing.
- Understand— step 1
Signers who know what they're signing
Confusion is why signatures stall. Before anyone signs, every party can read the agreement in their language with plain-language explanations — so the signature comes with understanding, not hesitation.
- Plain-language explanations available to every signer
- Each party can read in their preferred language
- Fewer stalled deals, fewer disputes later
- Sign— step 2
Deliver it the way your signer actually works
Some signers live in email. Some only answer texts. Some are standing in front of you. XOsign sends the same agreement whichever way reaches them — and signing takes a secure link and any device, with no account required.
- Send by email, by SMS, or sign in person on your device
- Signers sign from any device — no account, no app to install
- Sign in minutes, from anywhere
- Sign— step 3
Track it to done
Stop wondering whether anyone opened it. XOsign tracks every agreement from sent to signed, with a signing history that records each step along the way.
- Status tracking from sent to viewed to signed
- A full signing history: who signed, when, and how
- Every completed document stored securely in one place
- Sign— step 4
A record you can verify — years later
A signed agreement is only as good as your ability to prove it. Every completed document is sealed with a tamper-evident record that anyone can confirm at xosign.ai/verify — no account required.
- Tamper-evident seal on every completed document
- Independent verification at /verify — no account needed
- Secure storage, so the signed copy is always findable
