Mask Hebrew & English personal details before sending them to ChatGPT, Claude or Gemini — 100% in your browser. Mechikon masks sensitive personal information before it ever reaches an AI chat. Type or paste into ChatGPT, Claude, or Gemini as usual. Mechikon detects names, ID numbers, phone numbers, emails, credit-card and other sensitive values, and replaces them with neutral tokens like [NAME_1] before the message is sent. The AI sees only the masked text. When the answer comes back, tokens are turned back into the real values automatically AND locally, in your browser. WHY MECHIKON - Your sensitive data never leaves your device. Masking and restoring happen entirely on-device. - The AI only ever receives masked tokens, never the real values. - Works in both Hebrew and English it detects the language of your text and masks accordingly. - Also handles files: drop a PDF, Word, or text file into the popup to get a masked, AI-ready version. WHAT IT DETECTS - Names, organizations, and places (Hebrew and English) - Israeli ID (Teudat Zehut), company numbers, IBAN, phone numbers - Email addresses, credit-card numbers, US SSN and US phone numbers - Anything you select by hand — click a word to mask it yourself. PRIVACY BY DESIGN - No accounts, no tracking, no analytics, no ads, no servers. - The only network request is a one-time download of the name-detection model from the Hugging Face CDN — model weights only, never your text. - The restore key is stored locally and expires after 24 hours. - Open source (AGPL-3.0) — you can inspect exactly what the code does. Made for anyone who wants to use AI chats without handing over personal data.
