From the maker
Hi HN, I built this because I kept pasting client data and API keys into ChatGPT without thinking. It detects 15+ types of PII as you type, masks them with placeholders like [PERSON_A] before sending, then unmasks the AI's response. Everything runs locally — no servers, no data collection, zero network requests. You can verify in DevTools. Built as a solo project using Claude Code.
From the website
43% of people surveyed shared sensitive work data with AI without their employer knowing. PiiBlocker masks PII before it reaches ChatGPT, Claude and more.
