About Spellbook

Spellbook is an AI contract drafting and review assistant built for legal professionals, operating as a Microsoft Word add-in that brings AI capabilities directly into the document editing environment lawyers already use daily. Built on GPT-4 and trained on commercial contract data, Spellbook suggests missing clauses, flags unusual provisions, explains legal language in plain terms, and drafts new contract sections from a brief description. Unlike general-purpose AI writing tools, Spellbook understands commercial contract norms and legal drafting conventions, making its clause suggestions appropriate for professional legal work. The Word integration means lawyers can review and draft contracts without switching applications, preserving existing workflows while adding AI assistance. Law firms using Spellbook report 50 to 70 percent reductions in routine contract task time, particularly on first-draft creation and playbook review. Pricing starts at $99 per user per month. Spellbook is primarily used by commercial lawyers and in-house legal teams handling high volumes of contract work who want AI that fits into existing Microsoft Office workflows.
