Spellbook Review
An AI-powered legal assistant that drafts, reviews, and redlines contracts inside Microsoft Word.
Is Spellbook Worth It?
Spellbook is worth it for law firms and in-house teams that draft and review high contract volumes. It drafts clauses, flags risks, and enforces Playbooks inside Microsoft Word, and licenses from $99 per user per month replace hours of manual redlining. The 7-day trial lets a team test the Word add-in first.
About Spellbook
Spellbook is an AI-powered legal assistant that drafts, reviews, and redlines contracts inside Microsoft Word. Spellbook runs as a Word add-in that reads a contract in real time and suggests clauses, edits, and risk flags. Scott Stevenson, Daniel Di Maria, and Matt Mayers co-founded the company in St. John’s, Canada, originally under the name Rally Legal. The Spellbook product launched in 2022 and now serves law firms, in-house legal departments, and solo practitioners.
Spellbook bundles several drafting tools into one Word sidebar. The contract drafting engine generates and rewrites clauses from a prompt. The risk review scans uploaded contracts for missing terms and liability gaps. The Playbook feature enforces a firm’s preferred positions, and Spellbook Associate runs longer legal tasks as an AI agent.
Spellbook raised over $80 million in total funding, including a $50 million Series B round in October 2025. The company runs on GPT-4 and other frontier large language models. Spellbook offers a 7-day free trial, and paid licenses start from $99 per user per month.
