What does NICH do?
NICH is a browser extension that protects your privacy when using AI chatbots like ChatGPT. It works by automatically detecting and replacing sensitive information in your prompts before they're sent to AI services. Names, email addresses, phone numbers, company details, and other personal data are converted into anonymous placeholders. This lets you get useful AI assistance without exposing confidential information.
The tool uses AI-powered entity recognition to accurately identify what needs to be anonymized. Everything happens locally in your browser - your data never leaves your computer or gets stored on cloud servers. After you receive the AI's response, NICH can restore the original information with a single click, maintaining the context and usefulness of the AI's output while keeping your data secure.
NICH is particularly valuable for professionals handling sensitive information. Legal teams can draft contracts with AI help, medical professionals can analyze records privately, and HR departments can process recruitment data safely. It's also useful for anyone who wants to use AI for email drafting or customer support without compromising client confidentiality or violating privacy regulations.
