FAQ from Nightfall for ChatGPT - Chrome Extension
What is Nightfall for ChatGPT?
Nightfall for ChatGPT is a purpose-built Chrome extension that acts as an intelligent privacy guard—scanning and sanitizing your ChatGPT input fields in real time to prevent sensitive data from ever being sent to the AI model.
How to use Nightfall for ChatGPT?
After installing the extension, it activates automatically on chat.openai.com. There’s no setup, configuration, or manual triggering—just start typing, and Nightfall works invisibly to protect every prompt.
How does Nightfall for ChatGPT identify sensitive information?
It combines contextual NLP analysis with deterministic rule-based scanning and customizable regex patterns—trained to recognize not just formats (e.g., 16-digit numbers), but semantic intent (e.g., “my AWS key is…”), reducing false positives while maximizing coverage.
Can Nightfall for ChatGPT remove sensitive information automatically?
Yes—by default, it redacts detected sensitive strings *before submission*. Users can also enable “masking mode” (e.g., replacing SSNs with ***-**-****) or configure custom actions per data type via optional settings.
Does Nightfall for ChatGPT work with other browser extensions?
Nightfall is engineered for compatibility and minimal interference. It only interacts with ChatGPT’s input fields and doesn’t require access to other sites or extensions—making it safe to run alongside password managers, grammar tools, or enterprise security agents.
Is Nightfall for ChatGPT free to use?
The core functionality—including real-time PII/PCI/API key detection and auto-redaction—is available at no cost. Premium tiers offer team policy management, audit logs, custom classifiers, Slack/Microsoft Teams alerts, and priority response for enterprise users.
