Our Verdict

Best for

Legal teams that want AI-assisted contract review and drafting without leaving Word or Google Docs.

Skip if

Your team needs a full standalone contract lifecycle management platform rather than a drafting add-in.

What is Spellbook?

Spellbook is an AI contract review and drafting tool that plugs directly into Word and Google Docs, letting legal teams redline agreements, draft clauses, and search past contracts without leaving the document editor they already use. Its Review feature flags risky language against a company's own playbook standards, while Draft generates clauses or full documents from templates and prior agreements. Additional modules include Associate for multi-document workflow automation, Compare for benchmarking contract terms against industry norms, and Ask for querying a contract library with cited answers. Spellbook reports over 4,500 legal teams across 80+ countries using the product, with customers including Dropbox, eBay, and Fender, positioning it as a tool for in-house legal teams and law firms that want to speed up routine contract work.
