Spellbook is an AI contract assistant that lives inside Microsoft Word, making it immediately accessible to any lawyer who already works in Word. It reviews contracts, suggests missing clauses, flags unusual terms, and drafts contract language — all within the existing Word environment without requiring workflow changes. The review feature compares contracts against market standards and flags provisions that are out of market, missing, or potentially unfavorable. The drafting feature generates first drafts of contract sections from a short description. The tool understands legal context well enough to produce output that's useful rather than generic. For small and mid-sized law firms and in-house legal teams that want AI assistance without enterprise implementation costs, Spellbook's Word integration minimizes adoption friction.
