I almost leaked my production database credentials to ChatGPT. So I built ShieldVault.

Preventing Data Leaks in AI Interactions: Introducing ShieldVault

In the rapidly evolving landscape of AI-powered tools, safeguarding sensitive information remains a paramount concern. Recently, I encountered a close call that underscored the importance of this issue: while debugging a technical issue, I nearly inadvertently pasted my live AWS credentials and database secrets directly into ChatGPT. Fortunately, I caught the mistake just in time, but the incident prompted me to take action.

To prevent similar mishaps, I sought a solution that could detect and alert me to the presence of sensitive data before any accidental submission. After realizing such a tool did not exist, I decided to develop one myself—ushering in ShieldVault.

What is ShieldVault?

ShieldVault is a free, browser-based extension designed to serve as a first line of defense against accidentally exposing confidential information during AI chats. Compatible with popular chat interfaces like ChatGPT, Claude, Gemini, and more, ShieldVault acts as a real-time safeguard, monitoring your input and alerting you to potential leaks before they happen.

Key Features of ShieldVault

• Comprehensive Pattern Detection: Implements 46 regex patterns targeting common secret formats such as API keys, tokens, and credentials.

• Real-Time Monitoring: Operates seamlessly as you type, providing instant feedback and warnings.
• Privacy-Focused Design: All detection processes occur locally within your browser, ensuring that no sensitive data leaves your device.

How It Works

ShieldVault continuously scans your input for credentials and secrets, alerting you before the information is submitted. This proactive approach helps prevent accidental leaks, giving users peace of mind while working with sensitive data in AI chat environments.
