Spellbook

Spellbook is an AI drafting and review assistant for lawyers that works directly inside Microsoft Word on contracts and transactional documents.

Overview

Spellbook embeds generative AI into the tool lawyers already use for drafting. It suggests clause language, redlines against playbooks, summarizes long agreements, and answers questions about a document in context. A database of precedent clauses helps lawyers reuse their own firm’s approved language instead of generic templates. Because it lives in Word with one-click acceptance of suggestions, adoption friction is minimal compared with standalone legal AI platforms. Playbook enforcement matters as much as drafting speed: lawyers define positions the firm will accept, and Spellbook checks incoming language against those rules during negotiation. Because suggestions are generated against the document in front of you rather than generic web text, the proposed language tends to match the surrounding definitions, cross-references, and defined terms.

Pricing

Spellbook is a paid subscription with tiered plans for individual lawyers, firms, and legal teams, typically billed annually. Each tier increases document volume and adds team features such as shared playbooks and administration; a trial is available for new users evaluating the tool. Firm-wide deployments can be rolled out per practice group, with shared playbooks maintained by knowledge management teams.

Who Is It For

Spellbook is designed for transactional lawyers, in-house counsel, and small to mid-sized firms that draft and negotiate contracts daily and want productivity gains without a heavy platform rollout. Users commonly report that routine agreements that once took hours are reduced to a focused review of flagged provisions.
