Sign anything with one stored signature
Save a signature once, then let Signupify (or Autopen) drop it onto NDAs, MOUs, contracts, agreements and any other paperwork that needs a human sign-off. An efficient, AI-assisted alternative to legacy e-sign tools.
What you can sign
NDAs
Mutual or one-way — countersigned in seconds.
MOUs & LOIs
Memoranda of understanding and letters of intent.
Contracts & SOWs
Service agreements, statements of work, addenda.
Business paperwork
Offer letters, vendor forms, policy acknowledgements.
Autopen — AI contract agents
Autopen is the Signupify AI agent (powered by Triangle OS) that reviews, extracts and signs documents on your behalf — within strict, opt-in permissions.
AI-assisted data extractions
Pull parties, dates, amounts, jurisdictions and renewal terms out of any uploaded document — automatically.
Obligation management
Autopen surfaces every commitment ("Party A delivers within 30 days…") and tracks it to completion.
AI-assisted review
Get a plain-English summary, risk flags and clause-by-clause comparison against your playbook.
Custom extractions
Define the fields you care about ("MSA effective date", "auto-renew window") and Autopen learns them.
AI contract agents
Standing agents that triage incoming agreements, route them to the right approver and counter-sign when policy is met.
Pre-determined signature
Save your signature once. Autopen applies it only on documents you've authorised — full audit trail included.
Built-in guardrails
Autopen will only ever sign documents inside Signupify, only with permissions you've explicitly granted, and every action is logged. Read the Autopen guardrails →
