Pseudora

Pseudora removes personal data from your prompt before it reaches an AI assistant, and puts the real values back in the answer. You keep working the way you already do — the model just never receives the parts it has no business seeing. WHY THIS EXISTS Pasting a contract, a support ticket or a customer email into ChatGPT is the fastest way to get useful work done, and the fastest way to send personal data to a third party you do not control. Most teams solve this by telling people not to do it. They do it anyway, because the alternative is doing the work by hand. Pseudora takes the other route: let people paste what they need, and make sure the sensitive parts never leave the browser in the clear. HOW IT WORKS 1. Write your prompt as usual on ChatGPT, Claude.ai or Gemini 2. Click Anonymize in the toolbar Pseudora adds next to the prompt box 3. Names, emails, phone numbers, tax IDs, IBANs and more are replaced with stable placeholders — [PERSON_1], [IBAN_1], [FISCAL_CODE_1] 4. Send the anonymized prompt and read the answer 5. Click Restore to bring the original values back into the reply Placeholders are consistent across a conversation: the same person stays [PERSON_1] from the first message to the last, so the model can still reason about who did what. That is the difference between anonymizing text and destroying it. TWO MODES Tag — reversible placeholders. Use this when you need the real values back. Surrogate — realistic stand-ins rather than tags. "Mario Rossi" becomes another plausible name instead of [PERSON_1]. Useful when the placeholder itself would throw the model off, or when you are producing something for someone else to read. WHAT IT DETECTS People, organisations and locations. Emrs, postal addresses. National tax identifiers, IBANs and other financial identifiers, card numbers, dates of birth. Detection is tdocument type — a contract and a medical note are not read the same way — and the type registry is configurable on your account.
