PISIGuard runs entirely in your browser. It spots names, email addresses, phone numbers, credit card numbers, passwords, API keys, and more, replaces them with safe placeholders, then puts the real values back into the AI’s reply. From your point of view, it’s mostly invisible; from the AI’s point of view, the sensitive stuff was never there.
Privacy Guardrail is a local-first Chrome extension that detects and anonymizes PII before text is pasted into ChatGPT, Claude, or Gemini, using Rust/WASM recognizers and optional in-browser transformer NER.
Local-first tool that strips emails, secrets, paths, and other identifying content out of your prompts before they reach a cloud LLM — and rehydrates the response locally.
Zero trace. Full answer. — Transparent Claude API proxy that anonymizes PII and sensitive data before it leaves your environment. From pentesters, to pentesters.
