Zelkir

AI shadow use governance — detect and govern unsanctioned AI tool usage in real time.

Stop sensitive business data from leaking into AI tools — in real time. Zelkir is a lightweight browser extension for businesses that need visibility and control over how employees use AI platforms. Designed for teams subject to data protection regulations, Zelkir runs silently in the background and alerts you when sensitive data is at risk. THE PROBLEM ─────────── Employees are pasting customer records, source code, financial data, and confidential information into AI writing and productivity tools every day — with zero oversight. For businesses subject to GDPR, HIPAA, or CCPA, this creates a compliance risk that is impossible to manage without dedicated tooling. HOW ZELKIR WORKS ──────────────── Detect — The extension monitors AI tool pages for sensitive data categories including PII, PHI, credentials, financial data, source code, and legal content. Classify — All classification happens locally in the browser. Raw prompt text never leaves your device. Enforce — Configurable policies per data category: log silently, warn employees, or block submissions entirely. Report — Usage events are sent to your Zelkir dashboard where admins can view risk scores, event logs, and generate compliance PDFs. PRIVACY FIRST ───────────── Your employees' prompt text is never transmitted or stored. Classification runs entirely client-side using pattern matching. Only metadata — event type, data category, risk level, tool domain, and timestamp — is sent to Zelkir servers. SUPPORTED AI TOOLS ────────────────── Zelkir works out of the box with the most widely used AI writing and productivity platforms. When your team opens any supported tool, the extension activates automatically — no configuration needed. Additional platforms are added regularly based on customer demand. COMPLIANCE FRAMEWORKS ───────────────────── Zelkir helps your organisation demonstrate compliance with major data protection regulations, including the EU General Data Protection Regulation (GDPR), the US Health Insurance Portability and Accountability Act (HIPAA), and the California Consumer Privacy Act (CCPA).
