Legal research, analysis, and drafting, powered by AI. CounselVault is a self-hosted legal AI appliance that runs entirely on hardware your firm owns. No cloud. No third-party data. No privilege waiver.
Built in response to United States v. Heppner, S.D.N.Y. (Feb. 2026) — the first federal ruling that AI-generated legal documents are not protected by attorney-client privilege.
“Because Claude is not an attorney, that alone disposes of Heppner’s claim of privilege.”
The court found that communications with consumer AI platforms fail every element of the privilege test. Sharing privileged information with a cloud AI may waive privilege over the original attorney-client communications.
The LLM runs on a Mac Mini in your office. Your prompts never leave your network. No third-party Terms of Service. No data collection. No model training on your inputs.
When counsel directs use of a self-hosted AI tool, the court’s own reasoning suggests a different outcome.
