FAQ

How does PromptGuard intercept prompts?
Our browser extension hooks into popular AI interfaces (ChatGPT, Claude, Copilot, etc.) and scans the prompt text client-side before it is submitted. Nothing leaves your browser until it's been cleared.
Can I create custom detection rules?
Yes. The dashboard lets you define custom regex patterns or keyword lists. Rules can be set to block the prompt entirely or automatically redact the matched content.
Is my prompt data stored or logged?
No. All scanning happens locally in the browser extension. Prompt content is never sent to our servers — only anonymized rule-match statistics are reported to your dashboard.
