What is Spellbook?
Spellbook is an AI contract review and drafting suite for transactional lawyers and in-house legal teams. It runs as a Microsoft Word add-in, where it redlines contracts, flags risky or non-standard terms, drafts clauses and full agreements, and answers questions about a document. The site says it uses GPT-5, Claude and other large language models.
Playbooks turn a team's legal standards into checklists that are applied on every review. Benchmarks compare terms against industry standards. Associate is an agent that works across several documents in a single matter, with the user overseeing it. A newer product, Autonomous Contract Management (ACM), pulls contracts in from email and Slack, runs a first-pass review and keeps signed contracts in a searchable repository that tracks renewals. ACM is currently in early access.
Spellbook is built for law firms and corporate legal departments. Pricing is based on the number of users and is quoted after a demo.
