Frequently Asked Questions

Is AI legal research accurate enough to use in court filings?

Tools like Casetext CoCounsel and Lexis+ AI only cite from verified legal databases, which significantly reduces hallucination risk. However, all AI-generated research must be verified by a licensed attorney before use in court filings. AI is a research assistant, not a replacement for legal judgment.

Are legal AI tools HIPAA or attorney-client privilege compliant?

Enterprise tools like Harvey AI and Casetext CoCounsel maintain SOC 2 compliance and are designed with privilege protection in mind. Always review the vendor's data processing agreement and avoid entering privileged client information into tools without verified security standards.
