The legal profession is embracing AI faster than many expected. According to Thomson Reuters, over 60% of law firms now use AI tools in some capacity. Here's how legal professionals are putting AI to work.

Legal Research

Contract Review & Drafting

Document Analysis & Due Diligence

  • Kira Systems — AI that extracts key information from contracts and documents during M&A due diligence.
  • ChatGPT (Free) — Upload legal documents for summarization, comparison, and analysis. Useful for first-pass review.

Important Caveats

AI in legal practice comes with critical responsibilities:

  • Always verify AI output — AI can hallucinate case citations. The famous Mata v. Avianca case showed lawyers being sanctioned for citing AI-generated fake cases.
  • Client confidentiality — Never input confidential client information into public AI tools. Use enterprise versions with data protection guarantees.
  • Ethical obligations — Check your jurisdiction's rules on AI use in legal practice. Many bar associations have issued AI guidance.
