Legal AI for Law Firms

The truth about Harvey AI: Impressive, but not built for every firm

Harvey AI helped spark the legal industry’s interest in generative AI. Built on OpenAI’s GPT technology and trained on legal data, it was developed to assist large organizations with drafting, contract analysis, and legal research. Its integrations through Microsoft Azure provide the scale and security that enterprise firms require.

However, while Harvey’s capabilities are powerful, they remain largely geared toward enterprise environments. Its pricing, deployment, and limited transparency make it difficult for most firms to adopt and integrate into everyday workflows. 

And for many legal professionals, the value of AI lies not only in what it can do, but in how easily it fits into the tools and systems they already use.

What to look for in a Harvey AI alternative

Choosing an AI tool for your firm means balancing innovation with reliability. Look for solutions that enhance your practice without compromising accuracy, compliance, or client trust.

Key criteria for evaluating legal AI tools:

• Transparent sourcing: Every output should cite verifiable case law and statutes.
• Authoritative data: The model must be trained on trusted, up-to-date legal sources.
• Workflow integration: It should fit seamlessly into the systems you already use—case management, billing, or document automation.
• Security and compliance: SOC 2 and ISO 27001 certifications are essential. Ensure your data isn’t used to train external models.
• Ease of adoption: Lawyers shouldn’t need prompt-engineering skills to get meaningful results.

The best AI tools don’t replace your judgment, they strengthen it with trusted insights grounded in real law. And with today’s technology, switching between separate tools to run your firm and practice law is quickly becoming a thing of the past.

What firms need next

The next generation of legal AI goes beyond enterprise-only solutions. Lawyers need tools that combine Harvey AI’s sophistication with greater accessibility, verifiable sources, and seamless workflow integration. That’s where Clio’s approach stands apart.

With Vincent AI, Clio brings trusted, enterprise-grade research intelligence to firms of all sizes. And soon, through Clio Work, those same research and drafting capabilities will live directly inside the Clio platform—making advanced AI available to every legal professional, without the barriers of cost or complexity.

Other legal AI tools to consider

While the power of Vincent AI sets the benchmark for legal-grade transparency and reliability, several other AI tools are making an impact across the industry:

Manage AI 

Clio Duo started as a simple way to make everyday tasks faster inside of Clio Manage, with thousands of legal professionals coming to rely on it to reclaim meaningful time each week. Duo’s evolution into Manage AI takes that foundation further. Manage AI is a firm-wide productivity engine that keeps work moving, deadlines tracked and scheduled, files organized, and bills out the door on time, all withing your practice management tool.

How Manage AI boosts how you work in Manage:

• Stay ahead of deadlines: Automatically pull dates from court documents, add them to the right matters, and keep calendars in sync to reduce the risk of missed deadlines.
• Plan your day with confidence: Surface priorities and reminders, then create tasks, notes, events, and expenses in a few clicks so every matter keeps momentum.
• Accelerate billing and cash flow: Generate draft invoices, route bills to the right approvers, set billing parameters, and streamline end-of-month billing so you can get paid sooner.
• Eliminate manual filing: Save emails, receipts, and attachments to the correct matter automatically. Everyone sees the latest file in the right place, every time.
• Automate repeatable work: Build tasks, stages, and checklists that standardize how your firm runs. Free your team to focus on high-value work instead of setup.
• Compose on demand: Draft motions, letters, and client updates, or turn long documents into clear, actionable summaries without leaving Clio.

How Manage AI shows up in real work:

• A new complaint hits your inbox: Manage AI extracts deadlines, creates a task list, and schedules key dates.
• It’s billing week: Draft invoices are ready for review, with approvals routed to the right people.
• You open a lengthy transcript: Manage AI delivers a tight summary and suggested follow-ups.
  

The result: fewer bottlenecks, faster payments, and more bandwidth for client service—all within the system your firm already trusts. 

While Manage AI does not offer the research capabilities of Vincent, it solves the daily pains that every law firm experiences. AI in your firm does not need to look complicated, and it can be secure and reliable, allowing you to open up some time in your day, and lift some administrative weight off your shoulders.

LexisNexis AI

With Lexis+ AI, the company brings generative AI into its existing ecosystem, helping lawyers draft memos, summarize cases, and ask natural-language questions across its proprietary database.

What stands out:

• Depth of data: Built on an extensive legal library, including case law, statutes, and secondary sources.
• Integrated drafting support: Suggests clauses, summaries, and legal analyses directly within the Lexis+ platform.
• Enterprise-grade security: Designed for large organizations with robust compliance, privacy, and data-governance frameworks.

Considerations for firms:

• High learning curve and cost: Optimized for enterprise teams, with pricing and setup that can be prohibitive for smaller firms.
• Limited interoperability: Works best inside the Lexis ecosystem, offering fewer integrations with other tools firms rely on daily.
• Citation transparency: While sources are provided, the AI’s reasoning process can be less visible, requiring careful human review.

LexisNexis AI is a strong option for research-heavy teams that already rely on Lexis tools and have the resources to implement enterprise-level systems. For most firms, its closed ecosystem and cost may limit accessibility and everyday use.

CoCounsel by Thomson Reuters

Part of Thomson Reuters, CoCounsel applies large-language-model technology to automate legal research, document review, and drafting. It’s positioned as a virtual legal assistant capable of handling tasks from deposition summaries to contract analysis.

What stands out

• Strong research reasoning: Built to understand complex legal language and return context-aware answers with relevant citations.
• Discovery and review expertise: Particularly effective for summarizing depositions or lengthy evidence sets.
• Enterprise-level governance: Benefits from Thomson Reuters’ established data standards and integration with Westlaw and Practical Law.

Considerations for firms

• Cost and scale: Currently targeted toward enterprise and upper-mid-market firms, which can make pricing and deployment challenging for smaller practices.
• Closed ecosystem: Deeply integrated with Thomson Reuters tools, offering limited flexibility for firms using alternative systems.
• Transparency and sourcing: Provides citations, but the underlying model training and data sources are not fully disclosed.

CoCounsel demonstrates how AI can extend beyond simple text generation to deeper analysis and review. However, like LexisNexis, it remains focused on enterprise environments with dedicated resources for implementation, oversight, and compliance.

Choosing the right AI for your firm

AI is transforming how lawyers work, but the best tools don’t just generate answers, they help you think, research, and act with confidence. While platforms like Harvey AI have advanced the conversation, most firms need solutions that are accessible, transparent, and built for the realities of legal practice.

Clio is leading that next chapter. With Vincent by Clio for verifiable legal research, Manage AI for daily productivity, and Clio Work bringing everything together in one connected workspace, firms of every size can harness AI safely and effectively.

It’s not about replacing lawyers, it’s about empowering them. With the right technology, your firm can deliver higher-quality work, faster, while staying focused on what matters most: your clients.
