Best AI Tools for Lawyers and Legal Professionals (2025)
AI is transforming legal practice, from document review to research. But legal professionals must navigate confidentiality, accuracy, and ethical obligations. This guide covers appropriate AI tools for legal work.
Important Caveat: Confidentiality and Accuracy
Before using AI tools with client information, consider:
- Bar association guidance on AI tool use (most jurisdictions require competence in AI tools you use)
- Data processing agreements for tools handling confidential client information
- Always verify AI-generated legal research against authoritative sources
- AI does not provide legal advice — you do
