AI contract drafting and review tool integrated into Microsoft Word for lawyers.
Spellbook is genuinely handy for standard NDAs and service agreements where its clause suggestions are spot on. On heavily negotiated, bespoke contracts though, the recommendations get generic and I end up ignoring half of them. It is a helpful assistant for routine work, less so for the tricky deals.
Strong on standard agreements
Generic on complex contracts
What makes Spellbook click for me is that it works directly in Microsoft Word, so there is no copy-pasting contracts into another tool. It suggests missing clauses, flags aggressive terms from the counterparty, and redlines in seconds. For a solo transactional practice it feels like having a junior associate reviewing every agreement.
I appreciate that Spellbook keeps me inside Word and the review pass it does is quick. But sometimes it flags issues that are not really issues and misses ones I would expect it to catch. I keep it on because the time savings on first reviews are real, just temper your expectations on accuracy.
I had high hopes but Spellbook's add-in caused Word to freeze and crash on my machine almost daily, twice losing unsaved redlines on a contract due that afternoon. Reinstalling and clearing the cache as support suggested did not resolve it. For a tool meant to save time, the instability cost me far more than it gave back.

Spellbook has cut down the grind of first-pass contract review for our in-house team and the clause library suggestions are often exactly what I need. The integration into Word is seamless. My only gripe is that performance slows noticeably on very long agreements, where it can take a while to load.
