Key Considerations
Confidentiality: Verify how each tool handles client data. Attorney-client privilege considerations may affect which tools you can use for client matters.

Bar rules: Many state bar associations have issued guidance on AI use in legal practice. Check your jurisdiction’s rules on disclosure and supervision.
