How it works
Everything you need to get approved faster
Build templates once
Define fields, approvers, and expiry rules. Reuse across your team.
Send in seconds
Submit requests from any template. Approvers get an email instantly.
One-click approval
Approvers approve or deny directly from email — no account needed.
Stay in the loop
Real-time status updates. Automatic reminders on expiry.
AI-powered
AI reads every request
before you do.
Write a plain-English policy once. Signauf evaluates every incoming request against it automatically — so routine approvals never need a human touch.
Assess
When a request arrives, AI evaluates it against a rule you write in plain English — no code, no configuration. It returns a recommendation: approve, deny, or abstain.
"Approve if the amount is under $500 and the category is office supplies. Deny if the vendor is not on the approved list."
Auto-approve
Enable auto-approve on any template and requests that pass AI review are approved instantly — no human in the loop unless the AI abstains or recommends denial.
Track overrides
Every AI recommendation and every human override is logged. Your analytics show agreement rate, override rate, and assessment coverage — so you know when a rule needs tuning.
