Catches API keys, passwords & PII the moment you hit send on ChatGPT, Claude, Gemini & Grok — and rewrites prompts expert-level. Every day, people paste things into AI chats that should never leave their machine — API keys in stack traces, passwords in config files, customer emails, phone numbers, credit cards. Once sent, you can't take it back.
PromptZap is a prompt firewall for ChatGPT, Claude, Gemini, and Grok. With Auto Scan on (it's on by default), every prompt is checked locally the moment you hit send — if it spots a secret, it pauses the send and lets you hide it with one click. And when you zap a prompt (one click or Ctrl+Shift+E), it also rewrites it into an expert-level one.
