Best AI Tools for Lawyers in 2025
Legal professionals are adopting AI rapidly. From contract review to legal research, AI tools can reduce billable hours on routine tasks while improving accuracy. Here are the best options.
TL;DR: Harvey AI for enterprise law firms. Claude for legal writing and analysis. CoCounsel (by Thomson Reuters) for legal research. ChatGPT for general drafting. Always verify AI output for legal accuracy.
AI Tools for Legal Work
Legal Research
- CoCounsel (Thomson Reuters) — AI-powered legal research integrated with Westlaw. Searches case law, identifies relevant precedents, and summarizes findings.
- Harvey AI — Purpose-built for law firms. Handles research, drafting, and analysis with legal-specific training.
- Perplexity AI — Good for quick legal research with cited sources. Free tier available.
Contract Review and Analysis
- Claude — Excellent at analyzing long documents, identifying key clauses, and flagging potential issues. Upload contracts directly.
- Ironclad AI — Automated contract lifecycle management with AI-powered review.
- Kira Systems — Due diligence and contract analysis for M&A.
Legal Writing and Drafting
- Claude — Best AI for legal writing quality. Clear, precise language with proper structure.
- ChatGPT — Good for first drafts of memos, briefs, and correspondence.
- Grammarly — Grammar and style checking for legal documents.
Important Considerations
- Accuracy: Always verify AI-generated legal content. AI can hallucinate case citations.
- Confidentiality: Use enterprise plans that do not train on your data. Claude and ChatGPT Team/Enterprise plans offer this.
- Ethics: Most bar associations require disclosure of AI use. Check your jurisdiction’s rules.
- Malpractice: AI is a tool, not a replacement for legal judgment. You are still responsible for the work product.
