Spellbook

Spellbook is an AI contract review and drafting platform that operates primarily as an add-in for Microsoft Word. It is designed to assist transactional lawyers and legal teams by suggesting clause language, flagging unusual or missing terms, and reviewing documents against firm playbooks. The platform uses large language models like GPT-5 and Opus to support contract workflows directly inside the user's document environment.

• Redline contracts and catch risks directly inside Microsoft Word
• Draft clauses and documents from scratch or using saved libraries and precedents
• Compare contracts to industry standards and market benchmarks
• Ask questions to get quick answers to complex legal inquiries with citations
• Encode legal standards into custom playbooks to standardize reviews
• Multi-document workflows powered by the Spellbook Associate agent
• Automatic storage and indexing of signed contracts for historical search

Pros

• Integrates directly into Microsoft Word to eliminate the need for switching windows during drafting and review
• Provides security measures including zero data retention agreements and SOC 2 Type II compliance
• Offers structured multi-document agents to handle complex legal matters across multiple files
• Includes customizable playbooks that let teams enforce their specific legal standards across reviews

Cons

• Specific tier pricing is not published on the page and requires contacting sales for a custom quote
• Requires a business email address rather than general public email providers for trials and registration
• Requires booking a demo for personalized pricing and to onboard larger team sizes

Spellbook fits transactional lawyers, in-house legal teams, and law firms ranging from small practices to global legal departments who want to streamline contract drafting, redlining, and review workflows. It is poorly suited for users outside of legal professions or those looking for transparent, self-serve online pricing tiers without speaking to a sales representative.

Pricing is structured around the number of team members on a license and custom quotes are required based on team size. Specific dollar figures are not published on the page, and interested buyers must book a demo to learn more. A 7-day free trial is available for lawyers and legal teams to test features and workflows.

Unlike standalone contract management systems or generic AI chat tools, Spellbook embeds its contract intelligence and multi-document agents directly into Microsoft Word where transactional lawyers already work. It uses zero data retention policies to ensure LLM providers do not train on user data, providing enterprise-grade security tailored specifically for legal confidentiality.

Works with Microsoft Word, Salesforce, Slack, and email systems for intake and document handling.

Spellbook is worth trying for transactional lawyers and in-house legal teams seeking to accelerate drafting and review cycles inside Microsoft Word, supported by a 7-day free trial and robust enterprise security. However, because exact pricing requires a sales demo, budget-conscious buyers must inquire directly to determine costs. Teams that do not use Word or legal AI tools will find less utility in the platform.
