GuardpupCheck My AI History
Did you paste a key into AI? Drop your ChatGPT or Claude export here. Guardpup checks every message you sent for API keys, passwords and card numbers, and tells you which ones to change.
Your export never leaves your computer. It's read right here, in this tab. This page
can't connect to anything: its security policy (connect-src 'none') makes your
browser block any request it tries, and the checking runs in a worker under the same rule.
To see for yourself, open your browser's developer tools on the Network tab, or turn off
Wi-Fi, before you drop the file.

What It Checks
- Only what you sent: your messages, and text you pasted in as an attachment. Not the AI's replies, images or other files.
- With Guardpup's own detector, the one in the extension: API keys and tokens from dozens of services, private keys, passwords in a message, card numbers, bank account and ID numbers.
- Never the whole value. Each one is listed with its first and last few characters (never more than a quarter of it) and its length, enough for you to recognise it.
- Emails and phone numbers are counted, never listed.

We Couldn't Read That
Replace These
Replacing means making a new key or password where it came from, then deleting the old one. Deleting the conversation isn't enough: the message was already sent.
| What | Where you sent it | Looks like |
|---|
Some may be false alarms: a project name or an ID can look like a key. You know which ones are real.
Nothing to replace. Nice. It only takes one paste, though.
Share Your Result
The card shows counts only: never a value, a hint or a conversation title.
Install Guardpup So It Doesn't Happen Again
Guardpup catches keys, passwords and card numbers as you paste them into ChatGPT, Claude or Gemini, and swaps them for realistic stand-ins before anything is sent. What you type, paste or attach never leaves your computer.
