Why private AI is the only safe choice for European businesses

ChatGPT is convenient. But when your team uses it with client data, you're handing that data to a US company with no GDPR guarantees. Here's what changes when AI runs on European infrastructure under European law.


Every week, employees at law firms, healthcare companies, and agencies are pasting sensitive client data into ChatGPT. They're not being reckless — they're trying to do their jobs faster. The consequences can be severe.

The problem with public AI services

When you use ChatGPT, Claude, or Gemini directly, your prompts are processed on servers in the United States. Under US law (the CLOUD Act), American authorities can request access to that data — even if it's stored in a European data centre.

This isn't theoretical. Italy's Garante temporarily banned ChatGPT in 2023 over GDPR violations. Germany's Hamburg Data Protection Authority and France's CNIL have issued formal guidance restricting how AI tools may process personal data. In April 2026, Microsoft's Flex Routing change extended the same exposure to Copilot — teams that approved it on the strength of EU residency now find their prompts can leave the EU under load.

What GDPR actually requires

The GDPR doesn't prohibit AI. It requires that personal data be:

  • Processed with a lawful basis
  • Kept within agreed geographic boundaries
  • Not shared with third parties without consent

Public AI services fail on point three almost by definition — your prompts go to their servers, their models, their infrastructure, sometimes to other regions on demand.

What private AI looks like in practice

With wozu.ai, two things happen on dedicated EU infrastructure, under EU law:

  1. The chat interface runs on a dedicated, single-tenant server we operate in the EU. Conversation history, uploaded files, generated images, meeting transcripts — all isolated to your organisation, never shared with another customer. You control access and deletion; we handle the hosting, updates, and security.
  2. Inference runs at Mistral AI — a French company subject to EU law, with data centres in Europe. Mistral does not use your prompts to train any model.

This means:

  • You control who has access and what's retained
  • Every workspace is single-tenant — isolated from every other customer
  • You can delete everything, instantly, if needed

Who this matters for

Law firms handle privileged client communications. A single accidental disclosure can end a professional relationship — or a career.

Healthcare providers work with patient data that is explicitly protected. AI tools processing this data need to be specifically compliant.

Financial services have strict requirements around data handling, especially for investment-related communications.

Any business with enterprise clients that has signed data processing agreements needs to be able to demonstrate control.

Getting started

wozu.ai is invite-only. Each workspace is provisioned for a specific organisation and matched to its actual use cases — no public signup, no shared tenant.
