Frequently Asked Questions

Is it ethical for lawyers to use AI tools?
Yes, most bar associations now permit AI tool use, but lawyers must maintain competence and oversight. The ABA has issued guidance that attorneys can use AI tools but must review AI output for accuracy, maintain client confidentiality, and disclose AI use when required. Always check your jurisdiction's specific rules.
Can AI replace paralegals for legal research?
AI tools significantly speed up legal research but work best alongside paralegals rather than replacing them. Tools like CoCounsel and Casetext can find relevant cases in seconds, but experienced paralegals bring contextual judgment and can verify AI findings. The best approach is AI-augmented paralegal work.
How accurate is AI contract review compared to manual review?
Leading AI contract review tools like Harvey AI and Luminance achieve 90-95% accuracy on standard clause identification. However, accuracy varies with contract complexity and unusual provisions. AI excels at catching standard risks and inconsistencies, while complex negotiations and novel legal issues still require human expertise.
