How it works
Three steps. No IT tickets. No VPN. No changes to how your team works.
Employee types a prompt with client data
A team member drafts a prompt in ChatGPT containing a client name, case number, or medical information. Leyr intercepts before it is sent.
PII is detected and anonymized automatically
Leyr replaces names, emails, phone numbers, and sensitive terms with consistent placeholders. The safe version is sent to the AI instead.
CISO sees the full audit trail
Every intercepted prompt is logged with the original, anonymized version, and AI tool used. Compliance reports in one click.
Built for security teams
Enterprise-grade protection that employees actually use — because it does not slow them down.
Real-time PII Detection
Catches emails, names, phone numbers, medical data, and custom sensitive terms in milliseconds — before they leave the browser.
Frictionless Installation
Browser extension — no VPN, no proxy, no IT ticket. Employees install in 2 minutes and continue using their existing AI tools.
