Spellbook

Spellbook is an AI-powered drafting and review assistant designed specifically for transactional lawyers, integrated directly into Microsoft Word. It uses GPT‑4o and other large language models to analyze contract language, propose revisions, and generate new clauses based on user prompts and deal context. The tool can review entire agreements or specific sections, flag potential issues, and suggest alternative wording aligned with market standards or user-defined playbooks. Lawyers can ask Spellbook to draft clauses from scratch, summarize complex provisions, or compare versions to identify substantive changes.

Key capabilities include automated issue spotting, consistency checks across defined terms and cross-references, and the ability to adapt language to different jurisdictions or negotiation positions. Spellbook can also generate first drafts of common agreements, such as NDAs, service agreements, and purchase contracts, which can then be refined by counsel. Because it operates inside Word, users can accept, reject, or edit suggestions using familiar document workflows. Typical use cases include accelerating contract review, standardizing language across a large document set, preparing redlines for negotiations, and reducing time spent on repetitive drafting tasks while maintaining legal accuracy and control.
