Pasting company or school documents into ChatGPT, Claude or Gemini risks breaching the GDPR. Anonymizing first, on your own computer, reduces the risk at the root.
Helps apply the principle of data minimization (Art. 5.1.c) and data protection by design (Art. 25). Replaces personal data with placeholders before the text leaves your computer, reducing the risk of breaches and of sharing data with AI systems.
Useful for AI literacy measures (Art. 4): helps educators, staff, professionals and corporate or public employees use language models more carefully, without sharing GDPR-protected personal data.
Automates manual redaction of personal data in seconds, saving the time spent searching for sensitive data and drafting minutes, notes and briefings for meetings and councils.
One tool to anonymize all your documents and restore the real data once the AI has done its work.
Upload contracts, decisions, circulars or resolutions as PDF. The app automatically finds and anonymizes names, tax codes, addresses, IBANs and private contacts.
Printed and scanned documents? The built-in OCR reads the scans, extracts the text and applies the privacy mask before anything reaches the internet.
Take a photo of a page with your phone or a screenshot. The app extracts the text in the image and anonymizes every sensitive reference.
Upload recordings of meetings, interviews or lessons (MP3, WAV, M4A). The app turns speech into text and anonymizes the personal data mentioned.
Record straight from the microphone during an interview, a consultation or a class council. When you stop, the app transcribes and anonymizes what was said.
The app’s added value. Paste the text produced by the AI (for example a summary or a draft by ChatGPT) and the app puts the real names and data back where they belong.
Select a PDF, a scan, an image or start an audio recording right in the app.
The app anonymizes the sensitive data locally. Copy the anonymized text and paste it into your favourite AI model (ChatGPT, Claude, Gemini).
Paste the AI’s answer back into the app and the real data is restored instantly for the final document.
Anonimizzatore IA is open-source, 100% free and local software. Here is what to know about the first launch and the simple steps to finish the installation on Windows and macOS. Click any screenshot to enlarge it.
Windows Defender SmartScreen and Apple Gatekeeper require costly annual commercial certificates to avoid warnings on newly released programs. As Retoria is a non-profit Third Sector organisation distributing the app for free and for the public good, these costs are not sustainable. The warning is a standard precaution: the software is safe, open and free of malicious code.
The app is local-first. To work without sending your documents over the internet, all AI models (personal data recognition, OCR engine and speech transcription) are bundled inside. Your documents do not leave your computer: processing runs on your hardware.
If a third-party antivirus is active (such as Avast, Norton, McAfee or Bitdefender), the novelty of the software may trigger a false positive and block the installation. Allow the app or pause the antivirus just for the installation, then turn it back on.
The first time you run the .exe file, if the blue Microsoft Defender SmartScreen screen appears ("Windows protected your PC"), click the «More info» link at the top left.
Right after «More info», the «Run anyway» button appears at the bottom right. Click it to start the guided installation.
Open the .dmg file and drag the app into Applications. On the first double-click, when the Gatekeeper warning "Anonimizzatore IA was not opened" appears, click «Done» (do not move it to the Bin).
Open the Mac System Settings, go to Privacy & Security, scroll to Security and click «Open Anyway» next to the app.
When the system asks for administrator authorisation, enter your Mac password or use Touch ID to confirm.
In the final dialog "Do you want to open Anonimizzatore IA?", click «Open Anyway». The app starts, and from then on it opens with a normal double-click.
We can guide you step by step through the installation and the first launch on your computer.

No. Anonimizzatore IA runs all personal data recognition, OCR and speech-to-text locally on your computer. Only to activate the advanced features, and then at most once every 30 days, the app sends retoria.it the activation code, a pseudonymous computer identifier, the operating system and the version: never your documents.
The AI-based algorithm automatically recognises 23 types of personal and sensitive data:
