Built for Developers, by Paranoia.

Instant Auto-Scan

Triggered exactly when you hit Ctrl+V inside ChatGPT. No extra clicks, no broken workflows.

Syntax Preservation

We intelligently wrap redacted credentials in quotes. Your code stays syntactically valid so the AI can still debug it perfectly.

100% Zero-Trust

All regex parsing happens completely locally in your browser sandbox. Your data literally never leaves your laptop.

The "Oh Sh*t" Moment.

11:45 PM. The deadline is tomorrow.

You're staring at an authentication bug that makes absolutely zero sense. In a moment of desperation, you copy the entire server.js file and paste it into ChatGPT with the prompt: "Fix this."

Congratulations. You just uploaded your company's production STRIPE_SECRET_KEY and database passwords to an external AI model.

Enter SwapSensitive. The exact millisecond you paste your code, the extension intercepts it locally. It finds the API keys, replaces them with safe placeholders like "[REDACTED_STRIPE_KEY]", and preserves all your quotes and syntax.

ChatGPT still fixes your bug perfectly. Your data remains perfectly safe.

Our Privacy Policy is Simple.

We do not want your data.

We built SwapSensitive because we were terrified of accidentally pasting production database urls into ChatGPT. To solve a security problem, an extension must be perfectly secure itself.

  • No External Servers: We do not have an API. We do not have a database. Everything happens locally.
  • No Telemetry: We do not track how many API keys you paste.
  • Clipboard Security: The clipboardRead permission is used purely to scan text the exact second you paste it into the ChatGPT editor. It is instantly discarded from memory.
