PasteSafe — AI Paste Sanitizer

Protects API keys, emails and sensitive data when pasting into ChatGPT, Claude and Gemini. Detects and masks sensitive data.

PasteSafe protects API keys, emails and sensitive data when pasting text into AI chats like ChatGPT, Claude and Gemini. Developers often paste logs, configs, stack traces or debugging output into AI tools. This can easily expose API keys, emails or other sensitive data by accident. PasteSafe scans pasted text locally and detects secrets before they are sent. If sensitive data is detected you can either confirm the paste or automatically mask the values. Example: API key: sk-1234567890abcdef → API key: [API_KEY#1] PasteSafe detects and masks: • API keys • access tokens • emails • phone numbers • UUIDs / IDs • URLs • financial amounts Common use cases • debugging with ChatGPT • sharing logs with AI assistants • analyzing stack traces • pasting environment variables • reviewing configs with AI Supported AI tools • ChatGPT • Claude • Gemini Privacy-first design All processing happens locally in the browser. • no servers • no analytics • no tracking • no data collection PasteSafe is designed for developers, analysts and anyone using AI chats for debugging or data analysis.
