Problem
Teams using generative AI risk exposing personally identifiable information (PII) and regulated data in prompts, which can lead to compliance violations under regulations such as HIPAA, PCI, and SOX.
Solution
Blur provides a client‑side privacy layer that scans prompts in real time before they reach any large language model. It identifies and masks sensitive data across more than 20 PII patterns, including SSNs, credit card numbers, health information, and contact details. An Aggressive Mode adds stricter detection for HIPAA‑adjacent workflows. The extension works directly in popular AI web interfaces (ChatGPT, Claude, Gemini) and can be force‑installed via Chrome Enterprise policies, ensuring zero data leaves the user’s device. Organizations pay only for active users, with a free tier that offers basic detection without requiring an account.
