A Word plugin that's added an agent
Spellbook is built around a Microsoft Word add-in: it redlines contracts against your playbooks, benchmarks terms against market standards, and drafts from your own templates, all inside the document you're already editing. In 2026 it added "Associate," described as an AI agent that can work through multi-document legal matters under a lawyer's oversight, a genuine step beyond single-document redlining, and a sign the company is trying to grow past being a pure Word plugin.
It's also genuinely easy to try: Spellbook ships a self-serve 7-day free trial with no sales call required, and says it's trusted by 4,500+ in-house teams and law firms with a 4.7 G2 rating. For a team that lives in Word and just wants better contract review, that's a low-friction way to find out if it fits.
