About Spellbook

Spellbook is a commercial AI tool for contract work. It is designed for transactional lawyers, both in law firms and in-house teams, and runs inside Microsoft Word so that reviewing and drafting happen in the document the lawyer already has open. It uses large language models from outside providers to suggest edits, flag risks and answer questions about an agreement.

The product is organized around several functions: Review redlines a contract and surfaces risks, Draft writes clauses from scratch or from saved libraries, Compare checks a contract against industry standards, and Ask answers questions about complex terms. Associate handles multi-document workflows, and Playbooks let a team encode its own legal standards so reviews stay consistent.

Beyond Word, the vendor offers integrations with existing systems and an early-access product for managing contracts after signature. Spellbook is a hosted commercial service with a free trial and demo option, and its homepage targets industries such as healthcare, energy, financial services and technology.
