Harvey AI is an exceptional tool for lawyers doing research and document analysis. Zignature is the platform that collects signatures, automates workflows, and manages the signed document lifecycle. You need both.
Most legal AI comparisons miss this. Harvey and Zignature don't compete — they cover different parts of the legal workflow.
Legal Intelligence Layer
Harvey is a legal AI assistant for lawyers and legal teams. It reads, analyzes, and synthesizes legal documents — helping lawyers do faster research, better due diligence, and smarter contract analysis.
Operational Signing Layer
Zignature is the AI-powered platform that handles everything after the contract is drafted — sending it, collecting signatures, tracking status, storing signed copies, and syncing data back to your CRM.
If you use Harvey for legal intelligence, add Zignature to handle the operational signing workflow your clients experience.
After Harvey helps you draft or review, Zignature sends the document to your client for signature — with a professional branded experience, mobile-friendly signing, and automatic reminders.
Every signature collected through Zignature generates a court-admissible audit trail — IP address, timestamp, device, email verification. The legal evidence you need if a signature is ever disputed.
All signed documents are stored securely with full metadata, searchable by client, date, contract type, or status. Never lose a signed agreement again — and pull any document up in seconds.
Harvey for legal intelligence. Zignature for the signing workflow. Together, you have a complete AI-powered contract practice.
