SafePrompt
The safest secret is the one that never enters a prompt. SafePrompt helps spot potentially sensitive data before text is sent to an AI system.
Free local tool
Check text before sending it to AI
Paste a prompt, log, configuration, or other context. The check runs entirely in the browser: the text is not sent to a server or stored.
Do not paste real secrets just to test the tool. If a value is already known to be secret, remove it instead.
What it checks
Remove avoidable risk before sending
SafePrompt looks for common signs of sensitive data and replaces matched fragments with readable placeholders.
- API keys, access tokens, bearer/JWT values, and private keys;
- password/secret/token values in configuration and connection strings;
- emails, phone numbers, and payment card numbers;
- IP addresses and part of the infrastructure context.
The tool is not a complete DLP system. Its narrower goal is to make a fast local check a normal step before working context is shared with an external AI system.
