Contract review is a $25+ billion market ripe for AI disruption. Traditional review is slow and expensive—hours of lawyer time per contract. AI can extract key terms, identify unusual clauses, flag risks, and suggest standard language in minutes. The technology is mature enough for real use but requires human oversight.
What is AI Contract Review?
AI contract review tools analyze legal documents to extract key terms, identify risks, compare to standards, and suggest revisions. They use natural language processing trained on millions of contracts to understand legal language. Features range from simple extraction to full negotiation support.
Why AI Contract Review Matters
Contract review is a bottleneck—legal teams can't review every contract thoroughly. This leads to missed risks or slow deal cycles. AI handles routine analysis instantly, freeing lawyers for judgment calls. Businesses close deals faster with better risk visibility.

Frequently Asked Questions
Can AI replace lawyers for contract review?
No. AI handles extraction and initial analysis but can't replace legal judgment on risk tolerance, business context, and negotiation strategy. It makes lawyers more efficient, not obsolete.
How accurate is AI contract analysis?
High accuracy for common clauses and terms—90%+ for standard contracts. Accuracy drops for unusual contracts, poor document quality, or highly specialized terms. Always verify critical items.
Is AI contract review secure enough for sensitive deals?
Leading tools have enterprise security, encryption, and compliance certifications. Check SOC 2, data residency, and confidentiality terms. For extremely sensitive deals, consult your security team.
