Anonix® is our own product. The privacy proxy sits between software and the AI provider: before a request reaches ChatGPT®, Claude® or Gemini®, Anonix® replaces names, account details and case numbers with placeholders. In the response, it puts the originals back. The software changes two lines, the API address and the API key; for staff, nothing changes at all. Concept, software and SaaS operation are ours, and so are the name, the logo, the corporate design and the anonix.ai website.
Film
Brief
Every AI prompt is a data transfer. Staff paste patient data into ChatGPT®, specialist applications send citizens' data to the AI provider via API. Banning the tools achieves little; people keep using them, only without protection. A data centre in Frankfurt is not enough either, because the US CLOUD Act applies according to where the provider is based, not where the server stands. The goal was a way to use AI without personal data leaving the organisation.
How it works
There and back, in real time
- Request (Your infrastructure): leads to Detect and replace
- Detect and replace (Anonix®): leads to AI works with placeholders
- AI works with placeholders (AI provider): leads to Original data back
- Original data back (Anonix®): leads to Response with original data
- Response with original data (Your infrastructure)
Anonix® does not store the mapping; it exists only in memory while a request is processed.
Result
Anonix® checks every request in four stages: pattern recognition for fixed formats such as IBANs or tax IDs, language understanding for names, places and organisations in eight languages, custom industry terms with no training, and finally an independent AI. Same value, same placeholder, so the AI still understands what the matter is about. The mapping exists only in memory during processing. Streamed responses are restored as they arrive.

Name, logo and corporate design
The name and the logo are ours. The wordmark is a graphic of square modules on a fixed grid, drawn like a dot matrix. The A and the X are in signal yellow, and on its own the A is the brand mark. Yellow is a signal, not a background colour, and slate tones and white carry the rest. The recurring motif is the mechanism itself: original, placeholder, original.
