What Is Spellbook Legal?
Spellbook Legal is an AI-powered agreement drafting and review tool designed for lawyers and in-house legal teams. It works directly inside Microsoft Word, helping legal professionals draft, review, and improve contracts using artificial intelligence trained on legal language.
Primary users:
- Law firms (transactional practices)
- In-house legal departments
- Corporate counsel handling high contract volumes
Unlike generic AI chat tools, Spellbook is built specifically for contract workflows, not casual text generation.
How Spellbook Legal Works
Spellbook operates as a Word add-in and assists lawyers at multiple stages of contract work.
1. AI Contract Drafting
- Generates clauses and sections based on context
- Supports common agreements like NDAs, MSAs, employment contracts, and SaaS agreements
- Helps reduce drafting time while maintaining legal structure
2. Contract Review & Risk Detection
- Flags missing clauses
- Highlights unusual or risky language
- Identifies inconsistencies across documents
3. Market Benchmarking (Key Differentiator)
Spellbook compares contract clauses against market-standard language, helping lawyers understand how far a contract deviates from common practice.
This benchmarking feature is rarely explained clearly on competitor pages, yet it is one of Spellbook’s strongest advantages.
4. Microsoft Word Integration
Lawyers can work inside Word without exporting documents or changing workflows, which significantly improves adoption.
