In Plain English

AI-powered contract review and drafting tool that works inside Microsoft Word, trusted by 4,000+ legal teams.

Overview

Spellbook is an AI-powered legal assistant that integrates directly with Microsoft Word to help lawyers draft, review, and negotiate contracts more efficiently. Trusted by over 4,000 legal teams worldwide, Spellbook is purpose-built for transactional lawyers who spend significant time on contract work. The platform leverages multiple large language models including GPT-5 and Claude, trained specifically on legal language, to suggest contract clauses, identify missing terms, flag potential issues, and generate entire contract sections based on user prompts. Spellbook's Word Add-In provides five core capabilities: Review (clause-by-clause analysis), Draft (generate new language), Ask (natural language questions about contract terms), Benchmarks (compare clauses against market standards), and Playbooks (save reusable review instructions). The newer Associate feature goes further — it's an AI agent that can work through multi-document legal matters with attorney oversight, handling complex tasks like reviewing an entire due diligence data room or cross-referencing terms across related agreements. Spellbook understands legal concepts and provides context-aware suggestions that maintain legal precision while dramatically reducing drafting time. The platform maintains industry-leading security with SOC 2 Type II compliance, GDPR and CCPA compliance, and Zero Data Retention agreements that prevent any data from being used for AI model training.

Key Features

Contract Review & Clause Analysis+

AI-powered clause-by-clause review that identifies risks, missing provisions, and unfavorable terms. Compares clauses against market benchmarks to flag outliers.

Use Case:

Associate attorney uploads a 40-page vendor agreement and gets flagged issues in minutes — missing limitation of liability, non-standard indemnification scope, and an overly broad IP assignment clause.

AI Contract Drafting+

Generates contract language from natural language prompts, maintaining legal precision and adapting to the document's existing style and terminology.

Use Case:

Partner describes needed termination-for-convenience clause with 30-day notice, transition assistance, and pro-rata refund terms — Spellbook drafts publication-ready language in seconds.

Playbooks (Reusable Review Instructions)+

Save and reuse specific instructions for how Spellbook should review certain document types. Codifies institutional knowledge into repeatable, consistent review processes.

Use Case:

Senior partner creates an NDA playbook specifying the firm's preferred positions on term, residual knowledge, non-solicitation, and injunctive relief — junior associates apply it to every incoming NDA for consistent review.

Associate (Multi-Document AI Agent)+

An AI agent capable of working through multi-document legal matters with attorney oversight, handling complex tasks across multiple related agreements.

Use Case:

Lawyer assigns Associate to review an acquisition data room containing 200+ contracts, flagging change-of-control provisions, assignment restrictions, and consent requirements across the entire portfolio.

Microsoft Word Native Integration+

Works directly within Word as an add-in, keeping attorneys in their existing workflow without switching applications or copy-pasting text between tools.

Use Case:

Attorney redlines a lease agreement in Word while Spellbook suggests alternative language, flags missing commercial lease provisions, and explains unfamiliar regulatory terms in a sidebar panel.

Limitations & What It Can't Do

We believe in transparent reviews. Here's what Spellbook doesn't handle well:

⚠Microsoft Word only — no support for Google Docs, Apple Pages, or browser-based document editing, which limits adoption for teams on those platforms
⚠Custom pricing without public transparency makes it difficult to budget or compare costs without engaging the sales team
⚠Focused exclusively on transactional/contract work — not useful for litigation, regulatory compliance, or legal research use cases
⚠AI-generated clause suggestions can occasionally produce language that sounds correct but contains subtle legal imprecisions requiring careful attorney review
⚠Playbook creation and organizational setup requires meaningful upfront time investment from senior attorneys before the system delivers its full value

Pros & Cons

✓ Pros

✓Trusted by 4,000+ legal teams worldwide with strong adoption among both law firms and in-house departments
✓Native Word integration means zero workflow disruption — attorneys work in the same environment they already use daily
✓Multi-LLM approach (GPT-5, Claude) means the platform can leverage the best model for each task rather than being locked to one provider
✓Playbooks feature codifies institutional knowledge so junior associates can apply senior partner review standards consistently
✓SOC 2 Type II, GDPR, and CCPA compliant with Zero Data Retention agreements — critical for client confidentiality requirements
✓Associate agent handles multi-document matters that would take associates hours of manual cross-referencing

✗ Cons

✗Pricing is custom and not publicly listed — requires booking a demo, which slows evaluation for price-sensitive solo practitioners
✗Limited to Microsoft Word — attorneys using Google Docs, Apple Pages, or other document editors cannot use the platform
✗AI suggestions still require careful attorney review — the tool occasionally generates plausible-sounding but legally imprecise language
✗No litigation support — purpose-built for transactional/contract work and doesn't help with brief writing, discovery, or case analysis
✗Playbook creation requires upfront investment of senior attorney time to codify review standards before seeing efficiency gains

Frequently Asked Questions

How much does Spellbook cost?+

Spellbook uses custom pricing based on team size and whether you're a law firm or in-house team. Pricing is per-user and typically structured around annual commitments. You need to book a demo to get a specific quote. Legal AI tools in this category generally range from $150-$400/month per user, though Spellbook's exact pricing depends on your team size and plan.

Does Spellbook offer a free trial?+

Yes, Spellbook offers a 7-day free trial for lawyers and legal teams. For larger organizations, extended trials may be available. You can sign up through the Spellbook website or by booking a demo.

Is my client data safe with Spellbook?+

Spellbook maintains SOC 2 Type II compliance, GDPR and CCPA compliance, and uses Zero Data Retention agreements with its LLM providers. This means no contract text or client data is used to train AI models. The platform takes a defense-in-depth security approach with multiple redundant controls. This is particularly important for law firms bound by attorney-client privilege and ethical confidentiality obligations.

What's the difference between the Word Add-In and Associate?+

The Word Add-In provides real-time assistance while you work in a single document — reviewing clauses, drafting language, answering questions, and applying playbooks. Associate is an AI agent that operates more independently across multiple documents, handling complex tasks like due diligence reviews, data room analysis, and cross-referencing terms across related agreements with your oversight.

Does Spellbook provide legal advice?+

No. Spellbook is an attorney productivity tool, not a legal advisor. It assists with drafting, reviewing, and flagging potential issues, but all AI-generated suggestions require attorney judgment and review. The tool is designed to make lawyers more efficient, not to replace legal expertise.
