Spellbook is an AI-powered legal drafting assistant designed to help lawyers create, review, and analyze contracts more efficiently. Built by Rally, it integrates directly into Microsoft Word, allowing legal professionals to use advanced AI features without changing their existing workflows. Spellbook uses large language models to interpret contract language, suggest clauses, detect risks, highlight missing terms, and provide alternative wording based on best practices. It can also answer questions about a contract, summarize lengthy sections, and generate new legal text tailored to the context of the document.
By automating repetitive tasks—such as clause comparison, error spotting, and drafting boilerplate language—Spellbook helps lawyers save time, reduce mistakes, and focus on higher-value legal work. Its goal is to enhance legal accuracy and speed while maintaining control, transparency, and oversight for attorneys throughout the drafting process.
