PROTECT YOUR PRIVACY WHEN USING AI ASSISTANTS
NICH: GPT Anonymizer detects and replaces sensitive information in your text in one click before you share it with ChatGPT, Claude, Gemini, or any other AI tool. Keep your data private while still getting the help you need.

🔒 WHAT GETS ANONYMIZED
Personal names, email addresses, phone numbers, credit card numbers, dates and times, monetary amounts, URLs and web addresses, physical addresses, organisation names, geographic locations, and any custom terms you define.

📝 HOW IT WORKS:
ANONYMIZE YOUR TEXT: When you're ready to protect your data, simply click the NICH icon in your text field. NICH instantly converts personal details like names, emails, or organisation information, into safe placeholders.
DEANONYMIZE (Restore Text): When an AI response comes back, just highlight the text, right-click, and select Copy Deanonymised. A quick message will confirm that the restored text has been copied to your clipboard.
PASTE DEANONYMIZED TEXT: Finally, paste the restored content back into your email, chat, or document. All placeholders will automatically revert to the original details.
