Clean before AI finds names, national IDs, IBANs, addresses, phone numbers and companies in your text and replaces them with labels like [PERSON_1] before it goes to ChatGPT, Claude or Gemini. The AI only sees the labels; the real data comes back in its answer. Everything runs in your browser: no server, no account, works offline. Rules with checksums plus a small local AI model, 17 European languages, and a Chrome extension that cleans as you paste. Free.
