How we score
Each tool is scored out of 10 across four weighted criteria, based on hands-on testing and public pricing pages.
Spellbook
Spellbook is an AI copilot for contract review and drafting that lives entirely inside Microsoft Word. It is trained specifically on legal data, giving it higher accuracy than general-purpose AI when reviewing clauses and suggesting language. The platform offers clause-level market benchmarking, so you can compare your terms against real market data, and playbook enforcement to keep your team consistent across every deal. Because it operates directly within Word, there is no learning curve for attorneys who already live in that environment.
Best for transactional lawyers and in-house legal teams who work primarily in Microsoft Word.
Pricing starts at $99–$199 per user per month, making it one of the most transparent options available.
