Clean before AI — hide personal data before you chat with AI

Hides names, IDs, IBANs and addresses before they reach the AI — then shows the answer with your real data. 100% local.

``` Clean before AI hides personal and confidential data before it reaches an AI chat — and shows you the answer with your real data. Everything runs 100% on your computer. HOW IT WORKS 1. Paste as usual — an email, a contract, a medical report or a CV. If the text contains personal data, a small window appears before the AI site sees anything. 2. One click replaces names, ID numbers, bank accounts, card numbers, addresses, phone numbers, emails and company names with labels such as [PERSON_1]. A short note asks the AI to keep the labels. 3. The AI answers with labels. The side panel shows the answer with your real data, ready to copy. YOUR DATA NEVER LEAVES YOUR COMPUTER • No server, no account, no tracking, no analytics. • The key that links labels to real values lives only in your browser's session memory and is deleted when you close the browser. • Real data is shown only in the extension's own side panel and is never written into the AI website. MADE FOR EUROPEAN LANGUAGES Clean before AI understands ten European languages, from Slovenian and Croatian to German, Italian, French and English. It recognises national and tax ID numbers from these countries and checks them with their official checksums. It also understands grammatical cases, so "Janezu Novaku" is recognised as the same person as "Janez Novak". WHERE IT WORKS On popular AI chat sites such as ChatGPT, Claude and Gemini. A round button in the bottom-right corner opens and closes the side panel. The interface is available in six languages. Free, no account.

Please note: numbers with checksums are detected very reliably, but unusual names or indirect clues can slip through — take a quick look before sending. ```
