Spellbook
LegalEnterpriseVisit Site
AI contract review and drafting that lives inside Microsoft Word, where lawyers already work.
Overview
Spellbook made the correct product bet: lawyers are not going to move their drafting into a new web app, so the AI has to come to Word. It redlines agreements against your Playbooks (your firm encoded standards), drafts clauses from precedent, answers cited questions about a contract, and benchmarks a deal against thousands of comparable agreements. The Associate agent handles multi-document workflows. The company reports 4,500+ legal organizations across 80+ countries. For a small firm or a lean in-house team, Spellbook is the highest-leverage single AI purchase available, because contract review is the most repetitive, highest-volume, most rule-bound work on the desk. It is not a research platform — pair it with Harvey or a research tool if that is the need.
