Uses a 1.5B-parameter local privacy-filter model from Hugging Face to detect and redact PII from documents and screenshots — names, addresses, IDs — with context awareness rather than naive regex. Fully local, no paywall, no B2B tier, no cloud component; the dev built it as their first macOS app explicitly for people who handle other people’s data on a laptop. Not a chatbot — it just classifies, and it’s fast.
