Spellbook
Spellbook is an AI contract review and drafting platform built for transactional lawyers, and its defining choice is to live inside Microsoft Word rather than a separate app. It redlines and flags risk using Word's native Track Changes, surfaces missing clauses and risky terms with inline suggestions, and drafts clauses or whole documents from scratch or from a firm's preferred precedents. Its most distinctive feature is market benchmarking, comparing contract terms against industry data by sector, jurisdiction, and deal type, and a newer agent, Spellbook Associate, takes on multi-document work such as data-room materials, financing documents, and disclosure schedules. Launched in 2022 by a Toronto-based team and drawing on models including GPT-5 and Claude, Spellbook says it serves 4,500 teams across more than 80 countries and complies with GDPR, CCPA, and PIPEDA. Pricing isn't published; third-party estimates put individual access near $99 per user a month, with higher enterprise tiers, and as with any legal AI its output needs lawyer review.
