Ensuring Data Privacy During AI Interactions: Introducing Prompt Armour, a Free Chrome Extension

In the contemporary landscape of digital communication and AI-powered tools, privacy remains a paramount concern. Many professionals regularly utilize language models like ChatGPT for tasks such as debugging, content creation, and brainstorming. However, the inadvertent sharing of sensitive information can pose significant risks.

Recognizing this, I developed Prompt Armour, a free Chrome extension designed to safeguard your personal and confidential data before it reaches AI platforms like ChatGPT, Gemini, or Claude.

The Inspiration Behind Prompt Armour

The motivation for creating Prompt Armour emerged after reading about the recent Samsung data leak where internal code snippets and secrets were unintentionally shared via ChatGPT. This incident highlighted how easily sensitive information can be exposed, often without users realizing it. I realized that many users, myself included, might be forwarding private data without proper safeguards, increasing vulnerability.

What Prompt Armour Does

Prompt Armour acts as an intermediary between you and the AI, monitoring and screening your inputs in real-time. It scans your messages for common sensitive data types such as:

  • API keys and credentials (AWS, database connection strings)
  • Passwords and authentication tokens
  • Personal identifiers (emails, phone numbers, SSNs, credit card numbers)
  • IP addresses
  • High-entropy random strings (potential secrets that do not match known patterns)

When the extension detects such information, it highlights it within the input box, allowing you to review and redact specific sections with a single click. You can choose from various redaction styles, including:

  • Tagged replacements (e.g., EMAIL-1, AWS-KEY-2)
  • Complete masking of the sensitive content
  • Simple “REDACTED” labels

Additionally, Prompt Armour offers an undo feature, enabling you to revert redactions if needed.

Privacy-Centric Design

Built entirely within your browser, Prompt Armour does not rely on any servers or cloud services. This design choice ensures that no user data is transmitted or stored externally, maintaining your privacy and security at all times.

Compatibility and Availability

While primarily designed for ChatGPT, Prompt Armour also supports other AI platforms such as Gemini and Claude. The extension is freely available, with core features like PII detection, API key scanning, and various redaction styles provided at no cost.

Future Plans

While the basic version will remain free indefinitely, I plan to introduce a pro tier in the future. This upgraded version will offer advanced features such as custom regex pattern creation and team collaboration tools, catering to organizational needs.

Get Involved

Prompt Armour is my first solo project aimed at empowering users to maintain control over their data. I invite feedback on how it fits into your workflow and suggestions for features that could enhance its utility. Your input is invaluable in shaping a tool that truly addresses real-world privacy challenges.
