Law firms use AI without risking client confidentiality

The problem every law firm faces

AI tools dramatically accelerate legal work — drafting, summarising, research, translation. But the moment an associate pastes a client name, a case number, or a privileged communication into ChatGPT, that data leaves your firm and enters US infrastructure outside your control.

Most firms respond by banning AI use entirely — and watch productivity gains go to competitors — or by hoping employees follow a policy nobody reads. Neither works.

How Leyr protects legal work

Leyr sits between the lawyer and the AI tool. Before a prompt is sent, it automatically replaces client names, case numbers, matter references, and any other configured sensitive terms with consistent placeholders. The AI receives the structure of the question — not the sensitive content.

The lawyer sees the original prompt alongside the anonymized version before it is sent. They approve with one click. The AI response comes back with placeholders — which Leyr can de-anonymize in context if needed.

Compliance built in

Every AI interaction is logged: original prompt, anonymized version, AI tool used, user, and timestamp. When your managing partner or an auditor asks “what AI is being used with client data?” — the answer is available immediately. No reconstruction, no guessing.

Leyr runs on EU servers. Client data never crosses to US jurisdiction. GDPR Article 28 data processing agreement is included as standard.
