AI Tools for Lawyers: A Practicing Attorney’s Guide

I’m an attorney. I’ve been testing AI tools for legal work for 18 months.

Here’s what actually helps, what’s dangerous, and how the profession is really using these tools.

The Ethical Starting Point

Before any tool discussion:

Never input confidential client information into public AI tools.

ChatGPT, Claude, and similar services may use your inputs for training. That’s a confidentiality breach waiting to happen.

Options:

• Enterprise versions with data protection agreements
• Legal-specific AI with privilege protection
• Self-hosted solutions
• Anonymize before inputting

This isn’t optional. It’s malpractice prevention.

Legal-Specific AI Tools

Harvey AI

What it is: AI built specifically for legal work. Used by major firms.

Strengths:

• Trained on legal documents
• Privilege-aware design
• Contract analysis
• Legal research assistance

Cost: Enterprise pricing (expensive, contact for quote)

Verdict: If your firm can afford it, it’s the most capable legal AI. Not for solos or small firms.

CoCounsel (by Casetext)

What it is: Legal AI assistant for research and drafting.

Strengths:

• Legal research with citations
• Document review
• Deposition preparation
• Timeline creation

Cost: ~$500/month per user

Verdict: More accessible than Harvey. Good for mid-size firms.

Westlaw Edge / Lexis+ AI

What it is: AI features added to existing research platforms.

Strengths:

• Integrated with trusted databases
• Citations verified against actual cases
• Familiar interface
• Briefing tools

Cost: Varies by subscription

Verdict: If you already use these platforms, the AI features are worth enabling.

General AI Tools for Legal Work

ChatGPT / Claude

Use for:

• First draft generation
• Simplifying complex concepts for clients
• Brainstorming arguments
• Administrative writing

Never use for:

• Legal research (hallucinated cases are a real problem)
• Anything involving client details
• Final work product without review

The case citation problem:

AI will confidently cite cases that don’t exist. Lawyers have been sanctioned for this. Always verify every citation in Westlaw/Lexis.

Otter.ai / Fireflies

Use for:

• Client meeting transcription
• Deposition notes
• Dictation to text

Caution:

• Check confidentiality policies
• Consider privilege implications
• Some tools are HIPAA compliant, verify

Grammarly / ProWritingAid

Use for:

• Polishing briefs
• Catching errors
• Consistency checking

Verdict: Low risk, genuine help for writing quality.

What AI Actually Helps With

Contract Review

The task: Review a 50-page agreement, identify issues.

Without AI: 2-3 hours, easy to miss things.

With AI: Upload to appropriate tool, get flagged issues in minutes. Still need human review, but faster and more thorough.

Tools: Harvey, CoCounsel, Kira Systems

First Draft Generation

The task: Draft a standard motion to compel.

Without AI: 45 minutes even with templates.

With AI: Describe the situation, get a draft in 2 minutes. Spend 20 minutes editing.

Caution: AI drafts need significant editing. The structure helps; the details need work.

Legal Research

The task: Find relevant cases for an argument.

What AI does well: Finding starting points, suggesting research angles.

What AI does poorly: Accuracy. The hallucination problem is real and dangerous.

Best approach: Use AI for initial directions, verify everything in proper databases.

Client Communication

The task: Explain complex legal concepts to non-lawyers.

AI strength: Simplifying language while maintaining accuracy.

Example prompt: “Explain summary judgment to someone with no legal background, in 3 sentences.”

What AI Can’t Do (Yet)

Strategic Judgment

AI doesn’t understand:

• What a judge actually cares about
• When to settle vs. fight
• Client relationships and goals
• The unwritten rules of your jurisdiction

Courtroom Work

No AI is trying cases. The persuasion, reading the room, and adaptive argumentation remain human.

Novel Legal Arguments

AI predicts based on patterns. Truly creative legal strategy still requires human insight.

Ethical Judgment

“Should we take this case?” involves human values AI can’t replicate.

Risk Management

The Sanctions Problem

Multiple attorneys have been sanctioned for AI-generated briefs with fake citations. Don’t be one of them.

Prevention:

• Verify every citation
• Run AI drafts through research databases
• Disclose AI use if required by court
• Treat AI output as a starting point only

Confidentiality

Enterprise AI solutions: Usually have appropriate data handling

Consumer AI (ChatGPT, etc.): Assume data may be used for training

Best practice: Strip identifying information before using consumer AI

Malpractice Considerations

If AI-assisted work contains errors, the attorney is still responsible. AI is a tool, not a defense.

My Workflow

For research:

1. Start with Westlaw/Lexis (real databases)
2. Use AI to help understand complex concepts
3. Never rely on AI-provided citations

For drafting:

1. AI generates first draft
2. I rewrite significantly (50%+ changes typical)
3. Traditional review process

For contracts:

1. AI flags issues
2. I analyze each flag
3. Negotiate as usual

Time saved: Maybe 20-30% on drafting-heavy work. Research unchanged.

Firm Implementation Tips

Start Small

Pick one use case. Test it. Evaluate results before expanding.

Training Required

Attorneys need to understand AI limitations. A single bad experience can poison adoption.

Document Policies

Create clear guidelines:

• What tools are approved
• What can/cannot be inputted
• Review requirements for AI output
• Disclosure obligations

Monitor Developments

This space evolves weekly. Stay informed on:

• Ethics opinions from bar associations
• Court rules on AI disclosure
• New tool capabilities

Bottom Line

AI for lawyers:

• Useful for drafting and review
• Dangerous for research without verification
• Requires careful confidentiality management
• Saves time on some tasks, not transformative (yet)

Worth considering:

• Harvey/CoCounsel for well-funded firms
• Westlaw/Lexis AI features for researchers
• ChatGPT/Claude for non-sensitive drafting (with caution)

Essential rules:

• Never trust AI citations
• Protect client confidentiality
• AI assists, you’re responsible

The profession is adopting AI cautiously. That caution is warranted. Use these tools to work smarter, but never forget they’re tools - not replacements for legal judgment.
