What is Spellbook?
Spellbook works as a Word add-in that suggests contract redlines, flags risky or missing clauses, and drafts language in your firm's own style, aimed at transactional lawyers who live in Word rather than a separate review platform.
Key features
- Redline suggestions drafted directly inside Word
- Risk flagging for missing or unusual clauses
- Playbook customization matching firm-specific language preferences
- Clause library search across past contracts
- Summarization of long agreements
Pros
- Working inside Word itself avoids the "second platform" friction some legal AI tools have
- Playbook customization keeps suggestions consistent with firm style
- Genuinely speeds up first-pass review of routine commercial contracts
Cons
- Still requires a qualified lawyer to review every suggested change
- Less suited to novel, highly unusual contract structures outside its training
- Pricing requires a sales conversation, not self-serve
