About this extension

CleanMyPrompt automatically detects and removes sensitive data before it reaches any AI model — ChatGPT, Claude, Gemini, Copilot, and 25+ others.

What it protects:

API keys, JWT tokens, database connection strings
Names, emails, phone numbers, addresses, SSNs
Credit cards, IBANs, crypto wallets
GitHub tokens, Slack tokens, AWS credentials

How it works:

Auto-intercepts paste events on AI chat sites
Shows a shield notification with how many items were blocked
Toolbar popup lets you manually clean any text
All processing is 100% local — no server, no cloud, no logging

Token Squeeze: Compress verbose text before sending to AI to save money and context window space.
