AI contract drafting and review assistant that works inside Microsoft Word, built for transactional lawyers at smaller firms.

What it does

Spellbook is an AI contract drafting and review assistant that runs inside Microsoft Word. It suggests language as lawyers draft, reviews agreements for missing or risky terms, proposes redlines, and answers questions about the document in place, so lawyers never have to leave the editor they already work in.

The product is built on large language models and is aimed squarely at transactional lawyers at small and midsize firms, along with lean in-house teams. Setup is light compared with enterprise contract platforms, and the company offers trials through its website, which makes it one of the easier tools in this category to evaluate.

Spellbook deliberately stays focused on drafting and review rather than expanding into workflow, approvals, or a contract repository.
