fixaiprompt
Mask API Keys · 100% client-side

Mask API keys before they leak.

Paste a config file, an error message, a curl command, or a log line. FixAIPrompt finds every API key and replaces it with a safe placeholder. Works for AWS, OpenAI, Anthropic, GitHub, Stripe, Google, Slack, SendGrid, Twilio, and more — plus an entropy fallback for keys with unknown formats.
