AI in legal practice isn’t about replacing lawyers. It’s about eliminating the hours spent on tasks that don’t require legal judgment — research summaries, first drafts, document review, and client communication.

Here are seven tools that deliver real time savings.

1. CoCounsel (by Thomson Reuters)

Best for: Legal research, document review, contract analysis.

CoCounsel is built on GPT-4 but trained specifically for legal work. It searches case law, summarizes holdings, identifies relevant statutes, and reviews documents for key provisions. Unlike generic ChatGPT, it cites actual cases and flags when it’s uncertain.

Key advantage: It’s designed to minimize hallucination — the biggest risk of using general AI for legal work.

Pricing: Enterprise pricing through Thomson Reuters. Typically bundled with Westlaw.

2. Harvey AI

Best for: Contract analysis, due diligence, legal memo drafting.

Harvey is purpose-built for law firms. It drafts memos, analyzes contracts, and assists with due diligence. Major firms like Allen & Overy have adopted it. The output quality for legal writing is noticeably better than general-purpose AI.

Pricing: Enterprise only. Contact for pricing.

3. ChatGPT (with careful use)

Best for: Client email drafts, brainstorming arguments, explaining legal concepts in plain language, administrative tasks.

ChatGPT is useful for non-critical legal writing — client communications, internal summaries, and brainstorming. It should never be used for legal research without verification, as it fabricates case citations.

Critical rule: Never paste confidential client information into ChatGPT. Use it for generic templates and frameworks, then add case-specific details yourself.

Pricing: Free or $20/month for Plus.

4. Clio Duo

Best for: Practice management, time tracking, client communication.

Clio’s AI assistant works inside their practice management platform. It drafts client emails, summarizes case files, suggests time entries you may have missed, and generates billing summaries. If you’re already on Clio, this is a natural addition.

Pricing: Included with Clio’s higher-tier plans.

5. Spellbook

Best for: Contract drafting and review.

Spellbook works inside Microsoft Word and suggests contract clauses, flags unusual terms, and generates language based on your description. It’s trained on legal contracts specifically, so suggestions are more relevant than generic AI.

Pricing: Starts at $100/month per user.

6. Grammarly

Best for: Proofreading briefs, emails, and client-facing documents.

Legal writing demands precision. Grammarly catches typos, unclear phrasing, and inconsistencies that spell-check misses. The tone detector helps ensure client emails strike the right balance between authoritative and approachable.

Pricing: Free (basic), Premium $12/month.

7. Otter.ai

Best for: Depositions, client meetings, internal discussions.

Otter transcribes and summarizes meetings automatically. For client consultations, it captures details you’d otherwise need to write up manually. For internal case discussions, it creates searchable records.

Important: Check your jurisdiction’s recording consent requirements before using in client meetings or depositions.

Pricing: Free (300 min/month), Pro $17/month.

Ethical Considerations

AI in legal practice comes with specific ethical obligations:

• Confidentiality: Don’t input client data into tools that aren’t SOC 2 compliant or that use your data for training. CoCounsel and Harvey are designed for this. ChatGPT is not.
• Competence: You must understand the AI’s output well enough to take responsibility for it. “The AI wrote it” is not a defense.
• Supervision: AI output is a first draft. Every legal document, research memo, and client communication must be reviewed by a licensed attorney.
• Disclosure: Some jurisdictions now require disclosure of AI use in court filings. Check your local rules.

Where to Start

Solo practitioners: ChatGPT (free) for admin tasks + Grammarly for proofreading. Add Clio Duo if you’re on Clio.

Small firms: CoCounsel for research + Spellbook for contracts. The time savings on research alone typically justify the cost.

Large firms: Harvey or CoCounsel enterprise deployments with firm-wide training on ethical use.

The firms that adopt AI thoughtfully — with clear ethical guidelines and proper oversight — will deliver better work faster. That’s the competitive advantage.
