1. Spellbook: Top GC AI Alternative

Spellbook is an AI tool designed for commercial legal teams at both law firms and in-house departments. It integrates directly into Microsoft Word, helping lawyers draft and review contracts with greater speed and precision, eliminating routine contract work.

Unlike other borad-purpose legal AI tools, Spellbook is tailored specfically for contracts and commercial law. It is also the only contract review tool grounded in real-time market data, giving lawyers data-driven answers to "What's market?" in every negotiation.

Spellbook Features

While many GC AI competitors split their tools between a web platform and a Word add-in, Spellbook integrates its entire suite of features directly into Microsoft Word. This allows legal teams to work within their existing drafting environment without context switching.

Here are the core features that make Spellbook a leading alternative:

• Review: Instantly analyzes your entire document to flag risks, suggest improvements, and identify missing clauses. All suggestions appear as standard track changes in Word, keeping you in full control of the final document.
• Draft: Generates new language, from a single clause like for limitation of liability to a full agreement. It can pull from a library of standard provisions or use your firm’s own historical contracts to find and adapt precedent, ensuring the language matches the context of your current document.
• Ask: Functions as a contract-specific Q&A tool. You can ask questions about obligations, definitions, or risks directly within your document, and Spellbook provides answers with citations to the relevant contract language for easy verification.
• Compare to Market: Provides data-driven answers to the question, "What's market?" for any given term. It compares your contract against thousands of similar, anonymized agreements, with breakdowns by industry and jurisdiction, helping you negotiate from a position of strength.
• Associate: An AI agent that handles complex, multi-document tasks from a single instruction. You can delegate work like reviewing a data room for due diligence, preparing a full document package from a term sheet, or updating terms across multiple files at once.

Spellbook's AI Models & Architecture

Spellbook uses a multi-model approach, selecting from top OpenAI and Anthropic models for optimal performance depending on the task.

It uses retrieval-augmented generation (RAG) to ground outputs in your team's precedents, definitions, and playbooks and enriches them with real-time market data.

This "Market Grounding" approach ensures suggestions are relevant and defensible.

The system also improves over time through Preference Learning, adapting to your team's specific contract review style and making it a strong GC AI alternative.

Other Alternatives to GC AI

Beyond dedicated contract review tools, the market includes a range of GC AI competitors that focus on different aspects of the legal workflow. Here’s how some of the other top platforms stack up.

2. LexisNexis

LexisNexis embeds its AI assistant within its broader legal research platform, grounding answers in proprietary content like case law. While it offers drafting and analysis tools, it functions more as a research-first platform. Its contract review workflow is less integrated than other similar companies to GC AI, relying on a separate Word plug-in for redlining and offering limited native playbook functionality.

LexisNexis Features

• Legal Q&A: Provides answers grounded in LexisNexis's proprietary content, with citations.
• Drafting & Summarization: Generates and summarizes legal documents.
• Document Analysis: Allows users to upload and ask questions about documents or compare up to three files.
• M&A Benchmarking: Compares clauses against SEC filings and Practical Guidance content.
• Word Plug-in: Offers a separate add-in for clause-level redlining.

LexisNexis Pricing

• Pricing is seat-based with volume discounts available for larger teams.
• Promotional pricing and multi-year contracts may be offered.
• The Word plug-in for clause-level redlining is priced as a separate add-on.

3. Ivo

Ivo is a legal AI tool that focuses on contract review and negotiation through a Microsoft Word add-in. It uses pre-defined "playbooks" to enforce a company's negotiation standards, making it a fit for teams that need to apply consistent rules across many agreements. Unlike GC AI, which combines research and review, Ivo is strictly an execution tool. It lacks a research function and relies on rigid, pre-built logic rather than flexible AI analysis, which may limit its utility for more complex negotiations.

Ivo Features

• Playbook-Driven Review: Applies custom negotiation standards to contracts directly within Microsoft Word.
• Clause-Level Analysis: Reviews documents clause-by-clause, flagging issues and suggesting redlines based on playbook rules.
• Automated Outputs: Generates annotated agreements, issue lists, and summary reports for internal review.

Ivo Pricing

• Ivo is priced at $6,000 per user, per year.
• This includes playbook creation, onboarding, and ongoing support.
• Discounts are available for teams of 10 or more users.

4. Callidus

Callidus (StrongSuit) is a legal AI co-pilot that functions as a Microsoft Word add-in for contract review, drafting, and negotiation. While it offers a unique multi-model approach to AI and a research partnership with CourtListener, its playbook features are less developed than other GC AI alternatives. The platform is still establishing its market presence and is currently undergoing a rebrand.

Callidus Features

• Negotiate: Analyzes contracts against playbooks and provides redlines.
• Draft: Generates new clauses based on document context.
• Proofread: Checks for grammar, clarity, and brevity.
• Compare Contracts: Aligns external agreements with internal templates.
• Chat: An AI assistant for Q&A, summaries, and other tasks.

• Offers a flat-rate price of $3,000 per user, per year.
• Pricing is all-inclusive with unlimited usage, onboarding, and support.
• Discounts are available for larger teams or multi-year contracts.

5. LegalOn

LegalOn is a contract review tool designed for in-house teams that handle high volumes of commercial agreements. Unlike GC AI's broader workspace, LegalOn focuses narrowly on review and negotiation, using pre-built playbooks to enforce standards. This structured approach prioritizes consistency but may offer less flexibility for complex or unique agreements, making it a specific type of GC AI alternative.

LegalOn Features

• Playbook-Driven Review: Analyzes contracts against pre-built and custom playbooks directly within Microsoft Word.
• AI Assistant: A tool for ad hoc drafting, summarization, and answering questions about the contract.
• Issue Prioritization: Flags potential risks and missing clauses, categorizing them by severity.
• Attorney-Authored Guidance: Provides explanations and sample language for each identified issue.
• Web Application: Includes features for intake, matter management, and a template library.

LegalOn Pricing

LegalOn uses a per-seat, per-module pricing model. Costs vary based on team size and the combination of features enabled.

• Individual licenses start at roughly $3,500 per user annually.
• A five-user enterprise plan is approximately $40,000 per year.

How To Choose The Best GC AI Alternative

Choosing the right tool requires looking beyond feature lists to see how it fits your team's actual workflow. To find the best GC AI alternative for your practice, focus on these key factors.

1. Workflow Integration

Consider whether the tool operates within your existing software, like Microsoft Word, or requires you to switch to a separate web application. A tool that integrates directly into your drafting environment can minimize disruption and context-switching, saving valuable time.

2. Scope of AI Specialization

Evaluate whether you need a general-purpose legal research tool or a specialized platform built specifically for contract drafting and review. A tool tailored to contracts will often provide more relevant features and nuanced suggestions for commercial agreements.

3. Data-Driven Insights

The best tools ground their suggestions in more than just AI; they use real-world data to inform their analysis. Look for a platform that can benchmark your contract against market standards, giving you a data-backed position in negotiations.

Frequently Asked Questions

How do these AI tools handle confidential client data?

This is a critical concern for legal professionals. Reputable tools address this with specific security measures, often operating on a zero data retention policy, meaning your documents are not stored on their servers or used to train their AI models.

Look for providers that are SOC 2 Type II certified and compliant with data privacy regulations like GDPR and CCPA. It is also important to understand if ChatGPT is private, as some tools use large language models via APIs that have their own data policies. Always verify a tool's security posture before uploading sensitive information.

Can I trust the legal suggestions made by AI?

While AI can generate impressive text, it can also "hallucinate" or produce incorrect information. The reliability of AI suggestions depends heavily on the tool's architecture. Leading platforms use techniques like retrieval-augmented generation (RAG) to ground the AI's output in specific, reliable sources like your firm's precedents or curated legal databases.

This approach makes the AI's suggestions more accurate and verifiable. Given the known risks, where a lawyer was fined for using AI that produced fake citations, it is essential to always treat AI as a co-pilot and review its work carefully.

How does Spellbook specifically compare to GC AI?

The main difference lies in their core focus and integration. GC AI aims to be a broad workspace combining legal research with contract review, often within a web application. Spellbook, in contrast, is a specialized suite built exclusively for contract drafting, review, and negotiation, and it operates entirely within Microsoft Word.

This integration means legal teams can work in their familiar drafting environment without context-switching. Furthermore, Spellbook's analysis is grounded in real-time market data, allowing you to benchmark clauses against thousands of similar agreements. This data-driven approach to answering "What's market?" provides a distinct advantage during negotiations that is not a primary feature of GC AI.
