Spellbook

Spellbook is an AI-powered contract review assistant that works as an add-in directly inside Microsoft Word, letting lawyers draft, review, and negotiate contracts faster without leaving the document editor they already use for legal work every day. As a lawyer reviews a contract, Spellbook can suggest missing clauses, flag unusual or risky language compared to standard market terms, and draft redlines and comments automatically, functioning like an always-available junior associate familiar with a huge range of contract precedent rather than requiring a lawyer to manually cross-reference their own firm's template library or memory of past deals. Because it's built as a Word add-in rather than a separate standalone application, it fits naturally into existing legal workflows built around redlining and tracked changes, which matters a great deal for an industry where document format and version control conventions are deeply entrenched and resistant to tools that require switching to an entirely new interface. Spellbook can be customized with a firm's or company's own playbooks and precedent language, so its suggestions increasingly reflect an organization's specific negotiating positions and preferred contract language rather than generic best practices alone. It's aimed at in-house legal teams and law firms handling a high volume of commercial contracts, like NDAs, MSAs, and vendor agreements, where AI-assisted review can meaningfully cut the hours spent on relatively routine, repetitive contract work.
