This page is designed to help you find out whether Anonimizer is good and if it is the right choice for you.
Anonimizer is a desktop application for Windows and macOS that removes personal and confidential data from documents before you use them with ChatGPT, Claude, Gemini or any other AI tool. Processing happens on your computer. Document content is never uploaded.
Typical use: a lawyer summarising a contract, an HR specialist comparing CVs, an accountant checking invoices. These documents are full of names, addresses, ID numbers and bank accounts that should not end up in a third-party AI service.
How it works:
Scans are not turned into plain text with gaps. Black masks are placed directly on the original document, in the exact position of each fragment, so you get back a file identical to the source, with the same layout, stamps and signatures. Office documents keep their formatting, tables and styles.
Detection is strongest for Polish and EU identifiers (PESEL, NIP, REGON, KRS, IBAN, ID card numbers) and works for common formats in other languages. Images embedded inside Word and Excel files are scanned too.
Pricing: free plan with 5 documents per month, no credit card. Paid plans (Starter, Pro, Team, Enterprise) raise the limits and add offline mode and user management.
Built by Trustlayer, a Polish company. Used by law firms, public offices, HR and accounting teams that need GDPR compliance while still benefiting from AI.
