Spellbook alternatives: 7 AI contract review tools compared

Spellbook alternatives at a glance

This table compares what each vendor publishes about where its tool runs, how playbooks work, pricing and trial access.

Why lawyers look for Spellbook alternatives

Most lawyers comparing Spellbook alternatives are weighing price, playbook control and scope. Spellbook doesn't publish prices, so buyers book a demo for a quote. Gavel customers who were quoted report about $350 per user per month.

• Price visibility. Spellbook prices by the number of seats on a license and quotes through a demo.
• Who builds the playbooks. Spellbook's in-house package includes a playbook build service. Some teams would rather generate and edit playbooks themselves.
• Scope. Spellbook has added multi-document work (Associate) and, in October 2026, Autonomous Contract Management, which it describes as a replacement for legacy CLM. Teams that only want review and drafting in Word may not need that scope.

1. Gavel Exec: best for published pricing and playbooks you control

Best for: transactional lawyers and in-house teams who want to start without a sales call and keep playbooks in their own hands.

Gavel Exec is AI contract review and drafting software that runs inside Microsoft Word as an add-in and on the web. It returns priority-ranked redlines as tracked changes, margin comments and a list of missing terms, with the reasoning behind each change.

• Playbooks: start from built-in playbooks written by practicing attorneys, or generate rules from your own checklists, spreadsheets or signed agreements, then edit and share them.
• Benchmarking: see whether each provision is on-market, off-market or missing for your jurisdiction, industry and company size.
• Web app: batch analysis and multi-document comparison.
• Price: $160 per user per month, or $1,740 per user per year, with 25 free queries per user and no credit card.
• Security: SOC 2 Type II, Zero Data Retention agreements with its AI model providers, and no training on customer data.

Limits: Gavel Exec is built for transactional work. It isn't a case-law research tool, and native document management integrations such as iManage and NetDocuments aren't available yet.

2. GC AI: best for solo and fractional general counsel

Best for: in-house lawyers who want one assistant for contracts and everyday legal questions.

GC AI describes itself as "the legal AI for in-house counsel." It runs as a web app with a Microsoft Word add-in and connects to Gmail, Slack, Google Drive and HubSpot. Your team builds its own playbooks, and a Skill Library includes workflows for MSAs and DPAs.

• Price: $500 per month on the Individual plan. Team pricing is on request and billed yearly.
• Trial: 14 days, no credit card.
• Security: SOC 2 Type II and SOC 3, with zero data retention agreements with OpenAI and Anthropic.

Limits: we found no market benchmarking on GC AI's site, and it's built for in-house teams rather than law firms. Compare the two directly in GC AI vs Gavel Exec.

3. LegalOn: best for a large library of pre-built playbooks

Best for: in-house legal departments that want attorney-written playbooks on day one.

LegalOn calls itself "the leading AI platform for in-house legal teams." It works on the web and in Microsoft Word and ships 135+ pre-built playbooks written by its attorneys. Its Playbook Agent turns your templates and prior redlines into playbooks, and 2026 releases added a contract repository (Vault) and cross-document review.

• Price: per seat, quoted through a demo, with unlimited reviews per seat and no implementation fees.
• Security: SOC 2 Type II, ISO/IEC 27001 and ISO/IEC 27017.

Limits: no published price, and we found no benchmarking against external market data. See LegalOn vs Gavel Exec.

4. Ivo: best for enterprise in-house teams with large contract portfolios

Best for: legal departments at scaled companies that want review plus insight across their executed contracts.

Ivo describes itself as "an enterprise-grade AI contract intelligence platform for in-house legal and business teams." It applies redlines in Microsoft Word or Google Docs, and its Intelligence product searches across your contract repository. Ivo builds playbooks from your templates and contracts, and its legal engineering team helps digitize them during onboarding.

• Price: not published; evaluation starts with a demo.
• Security: SOC 2 and ISO 27001; Ivo says it never trains AI models on customer data.
• Customers: Uber, Shopify, Atlassian, Reddit and Canva, per its January 2026 funding announcement.

Limits: built for "in-house legal teams, not law firms," and its benchmarking compares against your own executed agreements. See Ivo vs Gavel Exec.

5. CoCounsel: best for firms that want Westlaw research next to drafting

Best for: firms already on Thomson Reuters that want research and contract work in one place.

CoCounsel is Thomson Reuters' AI assistant. CoCounsel for Microsoft Word covers contract review, drafting and playbook management using Practical Law contract playbooks, and the wider product connects to Westlaw and Practical Law. Thomson Reuters made the next generation of CoCounsel Legal generally available in the US in August 2026.

• Price: online pricing is available for firms with up to 10 attorneys; larger firms contact sales. Thomson Reuters lists discounts for two- and three-year subscriptions.
• Security: Thomson Reuters says user content and prompts aren't used to train CoCounsel; data is encrypted with AES-256 at rest.

Limits: the most value comes with Westlaw and Practical Law subscriptions, and transaction-term benchmarking (from its Noetica acquisition) wasn't confirmed as live when we checked. CoCounsel vs Gavel Exec compares the two for contract work.

6. Harvey: best for large law firms

Best for: Am Law firms and corporate legal teams buying one platform across practice groups.

Harvey describes itself as "legal AI tailored for leading law firms and corporate legal teams worldwide." It runs on the web with Word and Outlook add-ins, applies playbooks inside Word, and its Vault projects hold up to 10,000 documents for bulk review.

• Price: not published; access starts with a demo.
• Security: annual SOC 2 Type II and ISO 27001 audits; Harvey doesn't train underlying models on customer inputs or documents.

Limits: sold mainly to large organizations, with no self-serve trial. See Harvey vs Gavel Exec.

7. Legora: best for firms that want a collaborative workspace

Best for: law firms and in-house teams that want review, research and drafting in a shared platform.

Legora says it helps lawyers "review and research faster, draft smarter." Its Word add-in drafts, redlines and reviews inside the document, its playbooks let you set starting positions and red lines, and Tabular Review handles many documents at once.

• Price: not published; access starts with a demo.
• Security: SOC 2 Type II and ISO 27001; Legora says it won't use customer data to train or fine-tune models.

Limits: no published price or self-serve trial. See Legora vs Gavel Exec.

How to choose a Spellbook alternative

1. Decide who maintains the playbooks. If your lawyers will write and update positions themselves, look for self-serve playbook generation and editing. If you want the vendor to build them, LegalOn's library or Ivo's onboarding may suit you.
2. Check where the redlines land. Every tool here reaches Microsoft Word, but confirm that suggestions arrive as tracked changes you can accept or reject.
3. Ask for the price in writing. Only Gavel Exec and GC AI publish prices. For the others, ask about seat minimums, contract length and what's included.
4. Run the same contract through each trial. Use an agreement you've already negotiated and compare each tool's redlines with what you actually sent.
5. Confirm data handling. Look for SOC 2 Type II, zero data retention with AI providers and a written commitment not to train on your documents.

Switching from Spellbook: what to bring with you

• Your playbook or negotiation checklist, as a document or spreadsheet. Gavel Exec can generate playbook rules from it directly.
• Three to five signed agreements per contract type, to check the new tool against positions you've accepted.
• Your clause library or templates, if you keep one.
• A short list of the contract types you review most, so you test the playbooks that matter first.
