Spellbook
AI contract drafting and review built into Microsoft Word
Our Verdict
Spellbook (by Rally) is a Microsoft Word add-in that brings AI contract drafting and review directly into the tools lawyers already use. Powered by GPT-4, Spellbook can identify risks in contracts, suggest alternative language, automate redlining, and benchmark contract terms against industry standards. The platform offers customizable playbooks so firms can define their own review standards. A 7-day free trial gives full access, though ongoing pricing is custom for each firm. Spellbook is best for transactional lawyers and in-house teams whose primary work is contract drafting and review — it's not a general legal research tool like Harvey or CoCounsel.
