Frequently asked questions
What's the best AI for legal research in France?
Doctrine remains the reference for searching French case law and doctrine. Lexis+ AI complements well for international AI-assisted research. Harvey is powerful for firms handling large document volumes.
Does AI replace manual legal research?
No, it speeds it up: Doctrine and Lexis+ AI find relevant texts and decisions in seconds, but legal analysis and verification stay with the lawyer or legal team.
