2. Casetext CoCounsel, best for Westlaw-integrated research

Casetext CoCounsel is an AI legal assistant built on top of Thomson Reuters' Westlaw database. After Thomson Reuters acquired Casetext for $650 million, CoCounsel became the AI layer for one of the largest legal research ecosystems in the world. It handles legal research queries, reviews documents, and assists with deposition preparation.

If your firm already pays for Westlaw, CoCounsel adds AI capabilities without switching platforms. The integration means you get AI-assisted answers grounded in the same primary law database your team already trusts.

Key features

• Timeline creation from uploaded case documents

Cons

• Best value requires an existing Westlaw subscription, limiting its appeal to non-TR users

3. Harvey AI, best for BigLaw and enterprise legal teams

Harvey AI is built for the largest law firms and corporate legal departments. It provides sophisticated legal reasoning across contract analysis, regulatory research, and due diligence workflows. Harvey has raised significant venture funding and counts several AmLaw 100 firms among its clients.

The platform excels at handling complex, multi-step legal tasks that require nuanced reasoning. However, it comes with enterprise-level pricing and a sales-driven onboarding process, which puts it out of reach for most solo practitioners and smaller firms.

Key features

• Advanced legal reasoning for complex contract analysis and regulatory questions
• Custom model fine-tuning for firm-specific workflows and terminology
• Due diligence acceleration across large document sets
• Enterprise-grade security and compliance controls
• Workflow integrations with firm document management systems

Pricing

• Starts at approximately $1,000+/user/month (enterprise contracts only)
• Requires a sales process and custom agreement
• No self-serve option or free trial available

Pros

• Extremely sophisticated legal reasoning, purpose-built for complex enterprise matters
• Custom fine-tuning adapts the AI to your firm's specific practice areas and writing style
• Strong adoption among top-tier law firms validates the platform's capabilities

Cons

• Pricing at $1,000+ per user per month makes it inaccessible for solo and small firm lawyers
• Long enterprise sales cycle with no way to test the product before committing
• No self-serve option means solo practitioners and small teams are excluded entirely

4. Lexis+ AI, best for comprehensive primary law research

Lexis+ AI adds a generative AI layer to LexisNexis' massive legal database. It lets lawyers ask natural language questions and receive AI-generated answers grounded in Lexis' primary law, case law, statutes, and secondary sources. For firms that need the deepest possible legal database, Lexis+ AI delivers that with AI-assisted search on top.

The strength here is the underlying data. LexisNexis has decades of indexed legal content that few competitors can match in depth. The trade-off is cost: Lexis+ AI requires a Lexis subscription, and pricing runs well into five figures annually.

Key features

• Natural language search across LexisNexis' full primary law database
• AI-generated summaries and answers with citations to source material
• Shepard's Citations integration for case validation
• Practice area-specific search filters and analytics
• Integration with Lexis' broader product suite (Practical Guidance, Lex Machina)

Best for

• Large firms that already subscribe to LexisNexis and want AI capabilities added
• Practitioners requiring the deepest possible primary law coverage for US jurisdictions
• Research-intensive practices like appellate litigation or academic legal work

Pricing

• Approximately $17,500/year (varies significantly by package and firm size)
• Requires existing LexisNexis subscription for best value
• Custom enterprise pricing for larger deployments

Pros

• Access to one of the largest and most established legal databases in the industry
• Shepard's Citations integration provides trusted case validation directly within the AI workflow
• Decades of indexed legal content give it unmatched depth for US primary law

Cons

• Annual pricing in the five-figure range puts it beyond the budget of most solo and small firm lawyers
• Complex, opaque pricing structure makes it hard to estimate costs upfront
• AI features are strongest when paired with a full Lexis subscription, limiting standalone value

5. Paxton AI, best for citation-focused legal research

Paxton AI is a legal research platform built around citation accuracy. It focuses on delivering well-sourced answers to legal research queries, with a strong emphasis on verifying that every citation is real and correctly linked. For lawyers who have been burned by AI hallucinations, Paxton positions itself as the reliable research companion.

The platform covers US case law and statutes and provides a clean, focused interface for legal research. It does not try to be an all-in-one tool: its strength is doing research well and making sure the citations check out.

Key features

• AI legal research with high citation accuracy and source verification
• Direct links to cited cases and statutes for quick validation
• Clean, focused interface designed specifically for legal research queries
• Support for US federal and state case law and statutory research
• Research history and saved queries for ongoing matters

Best for

• Appellate practitioners and brief writers who need every citation verified
• Solo and mid-size firm attorneys focused primarily on US legal research

Pricing

• Plans start at approximately $159/month
• No free tier, but trial options may be available
• Pricing positions it between enterprise tools and budget options

Pros

• Strong emphasis on citation verification reduces the risk of citing non-existent cases
• Focused research interface keeps the experience simple and fast

• Primarily focused on US jurisdictions, limiting its use for international practitioners
• Higher price point than LegesGPT while offering fewer features overall

6. Spellbook, best for AI-powered contract drafting

Spellbook is an AI contract drafting assistant that works directly inside Microsoft Word. Instead of switching between your document and a separate AI tool, Spellbook analyzes your contract in real time and suggests clauses, flags missing provisions, and helps you draft language based on a database of legal precedents.

For transactional lawyers who spend most of their day in Word drafting and reviewing contracts, Spellbook integrates into the workflow rather than replacing it. The trade-off is scope: Spellbook is a contract tool, not a full legal research platform.

Key features

• AI contract drafting and clause suggestions directly inside Microsoft Word
• Automated detection of missing or unusual contract provisions
• Database of legal precedents for contract language recommendations
• Redlining and markup suggestions based on your position (buyer vs. seller)
• Clause library for frequently used contract terms and provisions

Best for

• Transactional lawyers who draft and review contracts as their primary workflow
• Corporate counsel handling high volumes of NDAs, MSAs, and vendor agreements
• Firms that want AI assistance without leaving Microsoft Word

Pricing

• Custom pricing (contact sales for a quote)
• Pricing details are not publicly listed
• Designed for firm-level licensing

Pros

• Direct Microsoft Word integration eliminates context-switching between tools
• Contract-specific AI understands legal provisions better than general-purpose AI
• Clause suggestions based on real legal precedents, not generic text generation

Cons

• Focused exclusively on contract drafting, not useful for case law research or litigation
• Requires Microsoft Word (no web-only or Google Docs option)
• Opaque pricing makes it hard to evaluate cost before engaging with sales

7. Everlaw, best for litigation and eDiscovery

Everlaw is a cloud-based litigation platform that brings AI to eDiscovery, document review, and case preparation. It uses predictive coding to surface the most relevant documents from large data sets and enables litigation teams to collaborate on review workflows in real time.

For firms handling large litigation matters with thousands or millions of documents, Everlaw streamlines the review process significantly. It is purpose-built for litigation, so it does not cover general legal research or contract drafting.

Key features

• AI-powered predictive coding for large-scale document review
• Cloud-based collaboration for litigation teams with role-based access
• Advanced search and filtering across document sets with visual analytics
• Court-ready production tools for formatting and exporting review results
• Integration with common legal hold and data collection platforms

Best for

• Litigation teams managing eDiscovery across matters with large document volumes
• Law firms handling class actions, regulatory investigations, or complex commercial disputes
• Legal departments that need collaborative document review with multiple reviewers

Pricing

• Enterprise pricing (contact sales for a quote)
• Per-matter or firm-wide licensing options
• No self-serve plans or public pricing

Pros

• Predictive coding significantly reduces the time and cost of large-scale document review
• Cloud-based collaboration allows remote teams to work on the same matter simultaneously
• Strong track record in complex litigation with court-tested production workflows

Cons

• Litigation-only focus means you still need separate tools for research, drafting, and other tasks
• Enterprise pricing and sales-driven onboarding exclude solo and small firm lawyers
• Steeper learning curve compared to simpler AI research tools

How to choose the best AI tool for your legal practice

1) What type of legal work do you do most?

The best AI for lawyers depends on your primary workflow. If you spend most of your time on legal research, case law analysis, and drafting across multiple practice areas, an all-in-one platform like LegesGPT or a dedicated research tool like Paxton AI will serve you best. If your work is primarily transactional (contracts, NDAs, M&A documents), Spellbook's Word integration is purpose-built for that. And if you're running large-scale litigation with eDiscovery needs, Everlaw is the clear choice.

• If you need research + review + drafting: start with LegesGPT
• If you need contract drafting only: evaluate Spellbook
• If you need eDiscovery and large-scale document review: look at Everlaw

2) What is your firm's size and budget?

Budget is the biggest differentiator in this space. Enterprise tools like Harvey AI ($1,000+/user/month) and Lexis+ AI (~$17,500/year) deliver deep capabilities but price out most solo and small firm lawyers. LegesGPT starts at $19.99/month with a 3-day free trial, making it the most accessible option for lawyers who want to test AI without a major financial commitment. Casetext at $225/user/month sits in the middle, best for firms already paying for Westlaw.

• Solo practitioners and small firms: LegesGPT ($19.99-$69.99/month)
• Mid-size firms with existing Westlaw: Casetext CoCounsel (~$225/user/month)
• Enterprise and BigLaw: Harvey AI or Lexis+ AI

3) Do you need multi-jurisdictional coverage?

Most AI legal tools on this list focus primarily on US law. If you handle matters involving international jurisdictions, your options narrow quickly. LegesGPT covers 38+ countries, making it the strongest choice for cross-border work. Lexis+ AI has some international coverage through its broader LexisNexis network, but most tools like Paxton AI, Casetext, and Spellbook are US-centric.

• For US-only practice: any tool on this list fits
• For international or cross-border work: LegesGPT is the strongest option

4) Test before you commit

Regardless of which tool looks best on paper, run it through your actual workflow before subscribing. Draft a few research queries you already know the answers to and check the AI's accuracy. Upload a real contract and see if the review catches what you would catch manually. LegesGPT offers a 3-day free trial on all plans, and several other tools offer demos upon request. Spending 30 minutes testing with real work is worth more than any comparison article.

FAQ

What is the best AI for lawyers in 2026?

The best AI for lawyers depends on your practice type and budget. For an all-in-one tool that covers research, document review, and templates at an affordable price, LegesGPT is the top choice. For BigLaw firms with enterprise budgets, Harvey AI offers the most sophisticated legal reasoning. If you already use Westlaw, Casetext CoCounsel integrates AI directly into that ecosystem.

Are AI tools for lawyers accurate enough to trust?

Modern legal AI tools produce significantly more accurate results than general-purpose AI like ChatGPT, because they are trained on and grounded in verified legal databases. However, no AI tool should replace final attorney review. The best approach is to use AI to accelerate your initial research and drafting, then verify key citations and conclusions yourself before relying on them in filings or client advice.

Can solo lawyers afford AI legal tools?

Yes. While enterprise platforms like Harvey AI and Lexis+ AI are priced for large firms, tools like LegesGPT start at $19.99/month with a 3-day free trial. That is less than the cost of a single billable hour for most attorneys, and the time saved on research and document review typically pays for the subscription many times over.

What is the difference between legal AI tools and ChatGPT?

Legal AI tools like the ones in this guide are built specifically for legal work. They search verified legal databases (court cases, statutes, regulations), provide citations to real sources, and understand legal context. ChatGPT is a general-purpose AI that can generate plausible-sounding legal text but often fabricates case citations. For professional legal work, purpose-built tools are significantly more reliable.

Which AI tool is best for contract review?

For contract review specifically, LegesGPT offers legal document review with automated risk identification and clause analysis starting at $34.99/month (Plus plan). Spellbook is strong for contract drafting inside Microsoft Word. For large-scale contract review as part of due diligence or M&A, Harvey AI and Everlaw handle high-volume document sets, though at enterprise pricing.

Is it safe to use AI for legal work?

Reputable legal AI tools implement security measures appropriate for handling confidential legal information. Most platforms on this list use encrypted data transmission, do not train on your uploaded documents, and comply with relevant data protection standards. That said, always review a tool's privacy policy and terms of service before uploading client-sensitive documents, and ensure your use complies with your jurisdiction's ethics rules on technology use.

What AI tool works best for legal research across multiple countries?

LegesGPT stands out for international legal research, covering 38+ countries with court cases and statutes from multiple jurisdictions. Most other AI legal tools on this list (Paxton AI, Casetext, Spellbook) focus primarily on US law. Lexis+ AI offers some international coverage through the LexisNexis network, but the broadest multi-jurisdictional AI coverage at an accessible price point is LegesGPT.

Do I need multiple AI tools, or will one platform cover everything?

For most lawyers, a single all-in-one platform will cover 80% of your AI needs. LegesGPT handles research, document review, and templates in one subscription. You would only need to add a specialized tool if you have a specific gap: Spellbook for high-volume Word-based contract drafting, or Everlaw for large-scale eDiscovery. Starting with one platform and adding specialized tools as needed is the most cost-effective approach.
