Sentinelle PII – Real-time local masking of personal data for AI chatbots

Summary: Sentinelle PII detects and masks sensitive personal data such as emails, phone numbers, and IBANs before it is sent to AI chatbots like ChatGPT, Claude, and Gemini. It replaces data with anonymous tokens locally in the browser and restores the original information in AI responses, ensuring no personal data leaves the device.

What it does

The tool scans text inputs and file uploads (CSV, Excel, Word) in real-time, replacing sensitive data with tokens before sending prompts to AI chatbots. It operates fully locally with no data transmitted externally and includes a team dashboard for GDPR compliance reporting.

Who it's for

Sentinelle PII is designed for employees and organizations using AI chatbots who need to prevent unintentional personal data leaks without IT setup.

Why it matters

It addresses the risk of sensitive data exposure by masking personal information before it reaches AI servers, enhancing data privacy and compliance.
