CoCounsel alternatives: 7 legal AI tools compared

CoCounsel alternatives at a glance

This table shows where each CoCounsel alternative runs, which research database it uses, and what each vendor publishes about price and trials.

Why lawyers look for CoCounsel alternatives

CoCounsel's strength is Thomson Reuters content. Its research is grounded in Westlaw and Practical Law, it connects to iManage and NetDocuments, its Word add-in offers custom and Practical Law pre-built playbooks, it reviews up to 10,000 documents against 100 questions, and Thomson Reuters' September 2026 release notes (published October 14, 2026) say the first phase of Noetica deal-term benchmarking is now live in the CoCounsel Legal web application in the United States. Firms compare alternatives for three reasons.

• The bundle and the term. CoCounsel Legal is sold with Westlaw Advantage and Practical Law Dynamic Tool Set on 1-, 2- or 3-year plans. A firm that mainly uses CoCounsel for contracts may not need the research bundle, though Thomson Reuters also lists CoCounsel Essentials plans on their own.
• The research source. CoCounsel answers from Westlaw. Firms that prefer LexisNexis content, research across many countries or run their practice on Clio look at Lexis+ with Protégé and Vincent by Clio.
• Pricing by firm size. Thomson Reuters lists CoCounsel Legal from $551.85 per month for solo and small firms. For Westlaw Advantage with CoCounsel Essentials, online pricing covers new customers at firms with up to 10 attorneys; larger firms go through sales.

1. Gavel Exec: best for replacing CoCounsel's contract work in Word

Best for: transactional attorneys, small firms and in-house teams who use CoCounsel mainly for contracts, or who want to keep Westlaw for research and add a dedicated contract tool.

Gavel Exec is AI contract review and drafting software that runs inside Microsoft Word as an add-in and on the web. It handles the contract half of what firms buy CoCounsel for: it redlines entire agreements as priority-ranked tracked changes, states the reasoning for every edit, adds margin comments and lists the terms a draft leaves out. Martin Algie of MIA Contract Lawyers puts first-cut review at about 5 hours per contract, down from about 15.

• Playbooks from your own documents: generate rules from checklists, spreadsheet playbooks or signed agreements (.docx, PDF or .csv), or start from built-in playbooks written by practicing attorneys in place of Practical Law's.
• What it cites: your precedent, uploaded matter files, EDGAR filings, government sources and the open web. With no case-law database, Westlaw or another research tool stays in your stack.
• Benchmarking: the web app flags provisions as on-market, off-market or missing for your jurisdiction, industry and company size.
• Price: $160 per user per month, or $1,740 per user per year, with 25 free queries per user and no credit card. Monthly billing carries no long-term contract, so you can run it alongside a CoCounsel term until renewal, and 10 or more seats get team pricing.
• Security: SOC 2 Type II, Zero Data Retention agreements with AI model providers including OpenAI, and no training on customer data.

Limits: Gavel Exec has no case-law research database and isn't built for litigation or e-discovery, so a firm that relies on CoCounsel for Westlaw research still needs a research platform. Native iManage and NetDocuments integrations aren't available yet.

2. Lexis+ with Protégé: best for replacing Westlaw research with LexisNexis

Best for: firms whose main CoCounsel use is research and who would rather work from LexisNexis content.

Lexis+ with Protégé is LexisNexis' legal AI for research and drafting, renamed from Lexis+ AI in February 2026 and billed as "Legal AI, built on authority." It answers from LexisNexis legal content, checks citations with Shepard's, generates motions, briefs, agreements and contracts from uploaded materials, and stores document sets in Vaults. For Word, LexisNexis pairs it with Lexis Create+, and the Protégé agent is available in Microsoft 365 Copilot and Teams.

• Citations: Shepard's confirms "the status and treatment of authorities" inside research and drafting, the LexisNexis counterpart to KeyCite in Westlaw.
• Price: firms with 1 to 3 attorneys can view costs in the LexisNexis Online Store; others get a quote. LexisNexis says pricing varies with factors such as the size of your organization.
• Trial: 2-day free trial.
• Security: LexisNexis says it never uses customer data to train AI models.

Limits: the Word workflow runs through Lexis Create+, so confirm what your quote includes, and two days is a short window to compare research results with Westlaw.

3. Vincent by Clio: best for cross-border research and small firms on Clio

Best for: firms that research across jurisdictions, and solo, small and mid-sized firms that already run their practice on Clio.

Vincent by Clio is a legal AI assistant built on Clio Library, which holds case law, statutes and commentary across over one billion documents from 100+ countries. Clio bought vLex, Vincent's original developer, for $1 billion in November 2025. The Clio for Word add-in, in beta since May 2026, proposes edits as native Word tracked changes, and Vincent can review incoming agreements against a custom playbook.

• Plans: Vincent features in Word need a Clio Work or Vincent for Enterprise subscription. Clio Work became available to solo, small and mid-sized firms as a standalone product in April 2026.
• Trial: vLex's Vincent page offers a free trial, and enterprise buyers can run a pilot on real matters.
• Security: SOC 2 Type II and ISO 27001, zero-retention agreements with model providers, and no training on customer material.

Limits: no published price for Clio Work or Vincent, and the Word add-in is newer than the research library. Test redlining on your own agreements before you rely on it.

4. Harvey: best for large firms that want research and drafting on one platform

Best for: large law firms and corporate legal teams that want research, drafting and bulk document analysis across practice groups.

Harvey is a legal AI platform used by more than 3,500 legal organizations, including 80+ Am Law 100 firms. For research, Ask LexisNexis, a paid add-on, answers from LexisNexis United States primary law (federal and state case law, statutes and regulations) validated with Shepard's, and Harvey says you don't need an existing LexisNexis subscription to buy it. Harvey for Word drafts from precedent and runs playbooks with a history of rule updates and versions, and Vault stores up to 100,000 documents and extracts data points from thousands of them at once.

• Price: not published; Harvey's pages lead to a demo request.
• Security: annual SOC 2 Type II and ISO 27001 audits. Harvey says it doesn't use inputs, outputs or uploaded documents to train underlying models.

Limits: no published price or self-serve trial, and Ask LexisNexis is priced as an add-on, so include it in your quote before you count on Harvey as a Westlaw replacement.

See Harvey vs Gavel Exec.

5. Legora: best for research, review and drafting in a shared workspace

Best for: law firms and in-house teams that want research, tabular review and Word drafting in one collaborative platform.

Legora is a collaborative legal AI platform whose Legal Research product draws on publisher partnerships and official sources, with attorney editors setting collection standards. Its announced content partners include the American Law Institute (Restatements of the Law, September 2026), the Singapore Academy of Law (Singapore Law Reports) and Manupatra in India. Tabular Review works like a spreadsheet across thousands of documents with each answer cited to its source, and the Word add-in drafts, redlines and reviews against playbooks of customizable rules.

• Price: Legora doesn't publish pricing. Gavel customers report about $3,000 per user per year with a $30,000 minimum.
• Trial: none published; access starts with a demo.
• Security: SOC 2 Type II, ISO 27001 and ISO 42001, and "zero AI training on your data."

Limits: Legora's research page doesn't say which sources cover United States case law, so ask how it covers your jurisdictions before treating it as a Westlaw replacement. A reported $30,000 minimum is a large commitment for a small firm.

See Legora vs Gavel Exec.

6. Spellbook: best for a contract suite in Word with a trial

Best for: transactional lawyers who used CoCounsel for contracts and keep research in a separate tool.

Spellbook is a contract review and drafting suite for Microsoft Word that calls itself "the complete contract AI suite" and says 5,000+ legal teams trust it. It covers redlining, drafting from precedent, playbooks that work as automated checklists, Compare to Market against industry standards and multi-document work in Associate, and it also runs as a Google Docs add-on.

• Price: Spellbook doesn't publish pricing and prices by the number of team members on a license. Gavel customers report about $350 per user per month.
• Trial: 7 days free; larger organizations can ask about an extended trial.
• Security: SOC 2 Type II, with Zero Data Retention agreements that prevent use of your data for training.

Limits: Spellbook's Ask searches public legal databases such as CourtListener, Case.law, CanLII and Justia, and its source list doesn't include Westlaw or LexisNexis, so firms that rely on CoCounsel for Westlaw research will still need a research platform. Its Playbook Build Service is listed for in-house teams only.

See Spellbook vs Gavel Exec.

7. Microsoft Copilot for Legal: best for teams already paying for Microsoft 365 Copilot

Best for: legal teams whose organization already pays for Microsoft 365 Copilot.

Microsoft Copilot for Legal is a set of more than 20 legal skills in Copilot in Word desktop and Cowork, announced as generally available on October 15, 2026, with rollout to Microsoft 365 Copilot commercial subscribers expected to finish by mid-December 2026. It reviews contracts against playbooks, produces "negotiation-ready redlines with tracked changes" and drafts new contracts from templates or previous contracts.

• Price: Microsoft 365 Copilot is $30.00 per user per month paid yearly, or $31.50 paid monthly with an annual commitment, on top of a qualifying Microsoft 365 plan. Microsoft 365 Copilot Business lists $21.00 per user per month paid yearly (shown at $18.00 on a first-year promotion) or $25.20 monthly.
• Trial: Microsoft offers a one-month free trial of Microsoft 365 Copilot Business, which requires a credit card; the Enterprise pricing page lists no trial.
• Legal research: Microsoft says outputs "may not incorporate live legal databases." LawNext reported launch research plugins from partners including Bloomberg Law, with Westlaw and LexisNexis absent from the list, though LexisNexis separately offers its Protégé agent in Microsoft 365 Copilot through the Microsoft Marketplace.
• Language: Microsoft says it tested the legal skills primarily in United States English.

Limits: Microsoft notes that Copilot "is not jurisdiction-aware by default," and research depends on partner plugins, so it replaces CoCounsel's contract features more readily than its Westlaw research.

How to choose a CoCounsel alternative

1. Sort a month of CoCounsel use into research and contract work. If research leads, start with Lexis+ with Protégé, Vincent by Clio, Harvey or Legora. If contracts lead, start with Gavel Exec, Spellbook or Copilot for Legal.
2. Decide between one platform and two tools. You can keep Westlaw for research and add a contract tool, or move both to one platform. Price both setups, including seat minimums and term length.
3. Test research on a memo you've already written. Ask each research vendor which jurisdictions it covers and how it validates citations (Shepard's at LexisNexis, KeyCite at Westlaw), then check whether it finds the authorities you cited.
4. Test contract work on an agreement you've already negotiated. Gavel Exec's 25 free queries, Spellbook's 7 days and Lexis+ with Protégé's 2 days let you run the same agreement through three tools this week. Compare each tool's tracked changes with the markup you sent.
5. Time the switch to your renewal. Thomson Reuters lists 12% off a 2-year and 18% off a 3-year subscription for Westlaw Advantage with CoCounsel Essentials, so weigh the discount against the commitment.

Switching from CoCounsel: what to bring with you

• Your CoCounsel renewal date and plan length. Plans run 1, 2 or 3 years, so time the switch to the end of your term.
• Your custom playbook positions, written out as a document or spreadsheet that Gavel Exec can turn into playbook rules.
• Research memos and the prompts your team reuses, to test whether a new research tool finds the same authorities.
• Recent signed agreements for your most common contract types, to compare suggested redlines with terms you accepted.
