Sigi
An AI e-signature and contract lifecycle agent that sends, tracks, and closes contracts with built-in clause review and risk detection.
Sigi is the WorksBuddy electronic signature agent. It manages the full contract lifecycle, from uploading or generating a document to capturing legally binding signatures and issuing a certificate of completion, with AI that reviews clauses, flags risks, and tracks signer behavior along the way. It is built for legal, sales, HR, and operations teams that need contracts signed without surprises.

What you can do
- Upload PDF, DOCX, and image files individually or in bulk (up to 20 at once), organize them into folders, schedule sends, and set auto-expiry.
- Route documents through any of seven signing workflows: sequential, parallel, self-sign, acknowledgement, approval chains, public embeddable forms, and scheduled future sending.
- Place signature, initial, text, date, and checkbox fields on any page, assigned per signer, with drawn, uploaded, or typed signatures.
- Run AI clause review, missing clause detection, risk analysis, and signing behavior prediction on every contract.
- Maintain an immutable, append-only audit trail with IP, device, and geolocation capture, SHA-256 document hashing, and a downloadable Certificate of Completion.
- Build reusable, version-controlled templates with custom fields, categories, and usage tracking.

How it connects
Sigi shares one data layer with the other WorksBuddy agents and can trigger them automatically. A signed contract can create an invoice in Inzo, update a deal in Lio, or start an onboarding project in Taro. See How Sigi connects.
