Anonymize your documents before pasting them into AI
Upload or paste a document. We detect personal data (IDs, phone numbers, emails, IBANs...) and replace it with tokens like [PERSON_1]. Copy the result into ChatGPT, Claude or Gemini and restore the answer with one click. Everything happens in your browser.
Paste text or upload a .txt, .md, .pdf or .docx. Sensitive data, including names thanks to the local AI, becomes tokens like [PERSON_1] or [ID_1].
Copy the anonymized text and use it in ChatGPT, Claude, Gemini or any other AI with peace of mind.
Paste the AI's answer here and get your original data back instantly. The token map never leaves your device.

Your document never leaves your browser
- All analysis runs on your device. Your document is not uploaded to any server, not even ours.
- The token map is stored only in your browser's local storage and expires after 7 days. You can delete it anytime.
- No sign-up, no accounts and no analytics on the content of your documents.
- Dual detection engine: patterns (IDs, phone numbers, emails, IBANs, cards, license plates) and an AI name model downloaded once and run entirely in your browser.
