Spellbook is an AI platform specializing in legal work, with a primary focus on reviewing, drafting, and managing contracts. It works directly within Microsoft Word and also offers integration with Google Docs and a web-based document editor. The platform enables users to review contracts and analyze their clauses to identify risks, errors, inconsistencies, and unusual terms, then suggests legal amendments and drafting suggestions that lawyers can review, modify, or accept. It also offers a “Draft” feature for creating legal clauses and documents from scratch or leveraging existing templates in the organization’s library, and an “Ask” feature that allows users to ask questions about documents, generate new text, and search the web and legal sources. It also includes Playbooks for applying custom review rules and instructions to contracts, and Associate, an AI agent for handling multi-document legal matters. The platform also offers capabilities for comparing contracts, searching past contracts, and extracting information from them, as well as managing, indexing, and searching signed contracts using natural language.
