I kept accidentally pasting real credentials into ChatGPT and Claude. Config files, logs, .env files — easy to miss something. So I built a tool to handle it automatically.

It replaces sensitive values with fake but structurally valid ones before anything reaches the AI. The structure is preserved so the AI can still help. When you get a response back, paste it in and it swaps everything back to the real values.

Runs entirely in the browser. No server, no accounts, nothing stored anywhere.

What it catches: API keys (AWS, OpenAI, GitHub, Slack and more), passwords, IPs, emails, JWTs, connection strings, PII (SSNs, credit cards, phone numbers), AWS/cloud identifiers, UUIDs, MAC addresses.

Browser extension auto-redacts on paste across 30+ AI sites so you don't have to think about it. Also a VS Code extension and a web tool.
