promptshield

We have hosted the application promptshield in order to run this application in our online workstations with Wine or directly.

Quick description about promptshield:

PromptShield scans text for emails, phone numbers, IP addresses, API keys and tokens, private keys, credit card numbers (Luhn-validated), IBANs (checksum-validated), crypto wallet addresses, SSNs and more, then offers a redacted version safe to paste into an AI chat.

The scan is never logged or stored. Available as a web app, a Windows desktop app, and a browser extension for ChatGPT, Claude, Gemini, Copilot and Perplexity.
