About GPT Guardian

In our digital age, it's easy to accidentally share more than intended. The GPT Guardian extension is your vigilant protector against unintentional sharing of sensitive data while using ChatGPT at chat.openai.com. GPT Guardian helps you protect PII data and adhere to HIPAA and PCI compliance. Perfect for those in the hospital, medical, retail, billing, customer support, and technical support industries to name a few. Key Features: Instant Alerts: Get immediate notifications if you're about to submit sensitive information like credit card numbers, phone numbers, email addresses, or social security numbers. Stay Local, Stay Private: We value your privacy. All checks are done locally on your device. We don't collect, store, or transmit any of your data. Adaptable: The extension smartly binds to the input box, ensuring consistent performance even if the chat UI undergoes changes. Ensure peace of mind with every message you send. Install GPT Guardian and keep your private details just that - private. Note: To prevent multiple alert annoyance while typing after sensitive data has been detected, the extension will alert you only once and will not check again until the prompt textbox in ChatGPT is cleared.
