Spellbook

Spellbook is a Word add-in built for transactional lawyers who draft and negotiate contracts all day. The autonomy here is narrow but useful: it suggests clauses, flags missing provisions, and generates disclosure schedules without you needing to prompt it each time. You open a purchase agreement, Spellbook scans it, and offers contextually relevant edits in the margin. The separate Associate agent handles multi-document workflows, comparing terms across a stack of NDAs or flagging inconsistencies in a merger's exhibits. I tested it on a software licensing agreement. Spellbook caught a missing limitation-of-liability cap and proposed three alternatives with jurisdiction-specific language. It also flagged vague indemnity wording and suggested tighter phrasing. The suggestions weren't always perfect, one proposed clause used Delaware precedent when the contract was governed by New York law, but the hit rate was high enough that I stopped second-guessing every margin note. The real value is in repetitive work. If you review ten SaaS agreements a week, Spellbook's clause library and auto-suggestions save hours. It knows transactional patterns: it'll prompt you to add a force majeure clause in a services agreement or flag a missing assignment provision in an asset purchase. The Associate agent shines when you're managing disclosure schedules across multiple documents, it cross-references exhibits and highlights gaps faster than a junior associate. Failure modes: Spellbook occasionally over-suggests, peppering a simple two-page NDA with ten edits when two would suffice. It also struggles with niche industries, I tried it on a clinical trial agreement and half the suggestions were generic contract boilerplate that missed the regulatory nuances. It's trained on common commercial deals, not specialised verticals. Compared to Harvey or Lexion, Spellbook's advantage is the Word integration. You don't leave your drafting environment. Harvey offers broader research capabilities but requires more manual prompting. Lexion excels at post-signature contract management but isn't as strong at drafting-time edits. Spellbook sits in the middle: excellent for lawyers who live in Word and draft repetitive commercial contracts, less compelling if you need cross-practice flexibility or deep research tools.
