Spellbook (formerly Rally) is an AI contract drafting and review tool that lives inside Microsoft Word. Rather than asking lawyers to migrate to a new platform, Spellbook layers GPT-powered drafting, clause suggestions, and risk detection on top of the editor where transactional work already happens.
Core capabilities include: clause-by-clause review with risk flagging, redline generation, benchmarking against industry-standard contracts, and a custom clause library that learns from your firm's templates. Adopted by over 4,000 legal teams across 80 countries.
Best fit: solo practitioners, boutique firms, and small in-house teams who want AI assistance without an enterprise implementation project. Pricing starts around $99/user/month with a 14-day free trial — accessible compared to Harvey's enterprise-only tier.
Spellbook is the contract-drafting category leader for non-Big-Law buyers. Where Luminance covers portfolio-level intelligence and Harvey serves AmLaw 100 firms, Spellbook owns the productivity-focused middle market.
Hands-on review pending. Scores reflect industry consensus.
