What is
Spellbook
?
Spellbook is an AI-powered contract drafting and review assistant that operates as a Microsoft Word add-in. It is designed for transactional lawyers who want AI-assisted drafting and review without leaving their Word workflow. Its most differentiated feature, Market, benchmarks contract terms against a proprietary dataset of more than 2,300 contract types. Spellbook positions itself as a lightweight, accessible tool, described as “Chat GPT for law”, and its customer base skews toward solo practitioners, small firms, and lean in-house teams.
Spellbook
Features
- AI drafting prompts: Suggests clauses and contract language inside Microsoft Word as you draft.
- Review & redlining: Flags risks and generates redlines using Word's native Track Changes.
- Market benchmarking: Compares your terms against 2,300+ contract types, but the benchmark is anonymous, aggregated data from other users' contracts, not your firm's own precedent or positions.
- Clause banks: Save and reuse preferred clause language, though this requires manual curation and metadata labeling.
- Simple playbooks: Create and apply basic review playbooks, though consistent results take significant trial and error to dial in.
- AI chat: A conversational interface for contract-related queries.
- Proofreading: Identifies grammatical and drafting errors in contracts.
Strengths
- Works natively inside Microsoft Word — no context switching required
- Accessible for smaller teams and solo practitioners with lower contract volumes
- Market benchmarking provides useful context on how contract terms compare across 2,300+ contract types
- Covers core drafting and review tasks including redlining, clause suggestions, and proofreading
- SOC 2 Type II, HIPAA, GDPR, and EU AI Act compliant, with Zero Data Retention agreements available
Considerations
- Connects to iManage, allowing users to manually select and pull individual documents into their workflows one at a time. Does not connect to NetDocs.
- No natural language or conceptual search — lawyers must search by keyword, requiring them to know exactly what they are looking for
- Draws on broad market data rather than your firm’s own deal history — recommendations do not reflect your firm’s standards or negotiated positions
- Clause banks require manual curation and metadata labeling, which is time-consuming and prone to errors
- No rule-based collection creation
- No ethical walls
- Not suited for mid-to-large firms or in-house teams that need scalable integration with deal data
What is Draftwise?
Draftwise is purpose-built for transactional lawyers, supporting contract drafting, negotiation, and risk assessment. Rather than relying on broad market data or documents a lawyer manually selects, it draws on a firm’s entire deal history automatically — applying firm-wide knowledge and clause patterns to every contract.
Draftwise Features
- Search & apply precedent: Pulls from your firm's full deal history to surface the right clause language, with no manual uploads or document selection.
- Review & markup contracts: Delivers accurate redlines, reliable clause replacements, and auto-updated definitions, so lawyers move fast without introducing errors.
- An intelligence layer built on your data: Learns from your firm's deals, clauses, and standards, so every recommendation reflects your firm's judgment, not generic guidance.
- Integrates wherever your precedent lives: Connects across DMSs, executed agreements, and knowledge repositories while respecting ethical walls and matter-level permissions.
- Playbook Studio & enforcement: Builds playbooks from your firm's precedent and negotiated positions, then applies those standards directly in drafting and negotiation.
Strengths
- Automatically applies firm-wide precedent to every contract — no manual document selection required
- Purpose-built for contract drafting and negotiation, the core workflow for transactional lawyers
- Works natively inside Microsoft Word and the browser, fitting into existing lawyer workflows
- Keeps teams aligned with firm standards through playbook enforcement
- Uses your existing ethical walls seamlessly within the drafting process
Considerations
- Less suited for isolated, one-off legal tasks that don’t depend on contract context
- Not designed for litigation, regulatory compliance, or legal research workflows
- Best value realized by firms/organizations with substantial deal history to draw from

If you’re focused on contracts and want to leverage your firm’s deal history at scale, Draftwise is built for that. If you need a lightweight AI layer for routine drafting and market benchmarking, Spellbook covers that ground.
