I built NICH after realising I couldn't use ChatGPT for my conflict research work without risking data leaks. It's a browser extension that: - Anonymises names, emails, and addresses in one click - Preserves context for AI to understand - Restores original data in AI responses - 100% browser-based (no cloud, data never leaves your device) Built it for researchers, lawyers, HR professionals or simply anyone handling confidential data who wants AI assistance without compliance nightmares. Free to use: https://www.nichtech.uk Would love feedback from the HN community!
