What is Spellbook?

Spellbook is an AI-powered legal tool for drafting, reviewing, and managing contracts. It helps legal teams improve compliance workflows and accelerate contract-related work.

Spellbook is a Legal AI contract drafting and review platform that uses GPT-4 inside Microsoft Word to suggest redlines, draft clauses, and flag risks in contracts, with pricing starting around $89/user/month. It is built primarily for in-house counsel, transactional attorneys, and small-to-midsize law firms who live in Word and want AI assistance without leaving their drafting environment.

Founded in 2014 by Rally (formerly Rally Legal) and launched as a dedicated product in 2022, Spellbook was one of the first legal AI tools to ship a GPT-4-powered Word add-in, and the company reports adoption by more than 3,000 law firms and in-house teams worldwide. The platform reviews contracts against a benchmark of millions of negotiated agreements, suggests missing clauses, drafts new language from natural language prompts, and assesses compliance with frameworks the user defines. Its 2025 "Spellbook Associate" agentic offering takes this further by autonomously performing multi-step review tasks, such as comparing a draft against a playbook or running diligence across a folder of agreements.

  • ✓M&A diligence workflows where Spellbook Associate can summarize terms across dozens of target-company contracts in a data room
