Spellbook.

Spellbook is a Microsoft Word add-in that uses large language models to draft, review and redline contracts. It suggests clauses and defined terms as you type, flags risky or missing provisions, summarizes agreements, compares a draft against your playbook and proposes tracked-change redlines. Users include small law firms, solo practitioners and in-house counsel at growing companies who spend their day in Word rather than in a contract management system. For a small business without a legal team, it is most useful when a contracts-savvy operator or outside counsel adopts it to speed up vendor, customer and lease agreements. It works with Word on Windows, Mac and web, with document storage in SharePoint or OneDrive, and offers a benchmarking feature trained on public deal data. A pilot would run the 7-day trial on five recent contracts, comparing Spellbook's flagged issues with the reviewer's own notes. Caveat: pricing is not public and requires an annual commitment, and the tool assists a reviewer rather than replacing legal advice.
