Spellbook
Your AI co-pilot for contract drafting — right inside Microsoft Word.
Best For
Lawyers and legal professionals who draft contracts in Microsoft Word and want AI assistance without switching tools.
Overview
Spellbook (by Rally) is an AI-powered contract drafting tool that integrates directly into Microsoft Word. Instead of making you copy-paste into a separate platform, Spellbook works where you already work. As you draft, it suggests clauses, flags potential issues, and can generate entire sections based on context. It is trained on a proprietary legal language model with data from billions of legal data points, making its suggestions more legally relevant than generic AI tools.
