Spellbook

Spellbook is an AI-powered platform designed specifically for transactional and commercial lawyers to streamline contract drafting, review, and revision. By integrating directly into Microsoft Word, Spellbook allows legal professionals to leverage advanced large language models, including GPT-4o and GPT-5, to suggest language, redline documents, and catch risks without leaving their familiar workflow.

The platform offers a comprehensive suite of tools that enable users to draft contracts from scratch or from saved libraries, receive quick answers to complex legal questions, and compare documents to industry standards. Spellbook's AI can handle multi-document workflows, making it especially useful for large, complex transactions that require consistency and accuracy across multiple agreements.

Spellbook emphasizes security and privacy, complying with major regulations like GDPR, CCPA, and PIPEDA, and offers Zero Data Retention agreements to ensure client data is not used for AI training. Trusted by over 3,600 law firms and in-house legal teams across more than 80 countries, Spellbook aims to eliminate tedious legal work and empower lawyers to focus on higher-value tasks.

With the recent integration of GPT-5, Spellbook has further enhanced its ability to spot nuanced legal issues, perform surgical document revisions, and maintain rich formatting in Word documents. This positions Spellbook as a leading AI copilot for lawyers seeking to increase efficiency and accuracy in contract management.
