What Spellbook does
Spellbook is an AI contract drafting assistant for lawyers that reviews, suggests edits, and generates contract language directly inside Microsoft Word where attorneys already work. The platform is used by transactional lawyers at firms and in-house legal teams to accelerate contract creation, identify missing clauses, and flag unusual terms. Spellbook's models are trained on millions of legal agreements, enabling it to suggest contextually relevant language based on deal type, jurisdiction, and negotiation position. The company's Microsoft Word-native approach reduces adoption friction compared to platforms that require lawyers to switch to a separate interface.
