Client Confidentiality

Why You Cannot Risk Cloud AI with Client Files

Protecting client secrets and work product under ABA Model Rule 1.6 and Formal Opinion 512.

The Cloud AI Privilege Risk

Uploading client discovery to third-party cloud AI vendors exposes confidential files to remote servers, risks waiving attorney-client privilege, and triggers affirmative client disclosure requirements under ABA Formal Opinion 512.

  • Client files stored on external cloud infrastructure.
  • Potential waiver of attorney work product protections.
  • Requires obtaining formal client informed consent waivers.

Lexnight processes every page directly on your computer with zero internet access. No documents are uploaded, no queries are logged, and no data leaves your control.

  • Zero outbound network connections—completely private.
