What is private AI?
Private AI is a complete AI stack that runs entirely inside an environment you control. The language model, retrieval over your documents, access management and logging — all of it sits on infrastructure you operate, or on a dedicated private cloud inside the EU. None of your data ever leaves that environment.
This is fundamentally different from public AI such as ChatGPT, Gemini or Copilot. With those tools, every question, every document and every customer name is sent to a US-based provider. Private AI removes that dependency. You keep control over your intellectual property, your customer data, and your compliance posture.
- The AI model runs on infrastructure you operate or inside the EU.
- Your data is never used to train public foundation models.
- Every data flow is auditable — you see exactly what happens where.
- No vendor lock-in to a single US hyperscaler.
- GDPR- and EU AI Act-compliant by default, without legal workarounds.
- Operates on your own documents, not a generic web corpus.
Private AI vs. private LLM — what's the difference?
The terms private AI and private LLM are often used interchangeably, but they are not the same. A private LLM is only the language model — the engine. Private AI is the complete platform: the model, plus the RAG pipeline that searches your own data, plus access control, plus audit logging, plus the integrations with Microsoft 365, SharePoint, your CRM or your line-of-business applications.
An LLM without that platform is like an engine without a car: technically impressive, practically unusable for enterprise workflows. Private AI is what you need to extract real value from AI on your own knowledge base.
Why enterprises are moving to private AI
Adoption of private AI is accelerating sharply in 2026. Research from Deloitte and KPMG shows that an increasing share of European and US enterprises are pulling back from public AI tools. The reasons keep recurring: data-leak risk, mounting compliance pressure from the EU AI Act, and the loss of control over intellectual property.
- No more data leakage to US vendors or third parties.
- Full compliance with GDPR, NIS2 and the EU AI Act.
- Your intellectual property stays inside your organisation.
- Higher answer quality, because the model works on your own documents.
- Independence from Big Tech price hikes or policy changes.
- A defensible position toward regulators, customers and auditors.
Private AI and the EU AI Act
The EU AI Act imposes strict requirements on AI systems that process personal data or drive high-impact decisions. For many sectors — healthcare, financial services, legal, HR — public AI has become difficult to defend legally. Private AI provides the certainty those teams need: you decide which data the system can access, you log every interaction, and you keep model outputs under governance.
That turns private AI from a nice-to-have into a compliance instrument. For many organisations, it is now the only way to deploy AI responsibly and demonstrably.
AI on your own data — how it works
Private AI uses a technique called Retrieval-Augmented Generation (RAG). Rather than retraining the model on your data — which is expensive and risky — the system searches your documents at the moment a question is asked. It retrieves the relevant passages, feeds them to the language model, and generates an answer with source attribution.
That gives you three major advantages. One: your data stays where it is — it is never baked into the model. Two: you can add or remove documents in real time, no retraining required. Three: every answer cites its source, so outputs are verifiable and explainable.
- RAG pipeline with hybrid search across your own documents.
- Source attribution on every answer — explainable and auditable.
- Real-time document add or remove without retraining.
- Role-based access — users only see what they are allowed to see.
- Full audit trail of every question and every response.
Who is private AI for?
Private AI matters for any organisation handling data that cannot leak. That covers far more than patient records or financial transactions — it also includes proposals, contracts, R&D reports, HR files and strategic plans.

Public-AI risks that private AI solves
Research from national cybersecurity centres and Capgemini shows that public AI tools have become one of the fastest-growing categories of enterprise security risk. Employees routinely paste customer data, source code or contract details into ChatGPT or Copilot. That data then travels to servers outside the EU and can end up in training corpora.
- Shadow AI: employees use public tools without IT visibility.
- Data leakage via prompts containing customer names, IDs or contract values.
- No audit trail of what happens to the data once it is sent.
- Indefensible toward auditors, DPOs and regulators.
- Exposure to EU AI Act penalties (up to 7% of global revenue).
What does private AI cost?
The cost of private AI depends on scale, integrations and number of users. In practice, private AI often replaces multiple licences — Copilot, ChatGPT Enterprise, separate knowledge-base tools — and reduces consulting hours. Total cost of ownership typically falls below an equivalent public stack within 12 to 24 months, with materially less risk.
We work in transparent phases: a short readiness scan, a pilot within a single department, then a staged enterprise roll-out. No surprises at the end.
Private AI for mid-market
Private AI is no longer reserved for global enterprises. Thanks to open-weight models such as Mistral, a complete private AI stack is now viable for mid-market organisations as well. We design and run the environment, manage the model, and handle the updates. Your team brings the use cases.
How to start with private AI
A successful private AI programme never starts with the technology. It starts with the question: where in your processes is the most time lost in searching, summarising or drafting answers? That is your first use case. From there, we build the minimum stack that solves the problem — and expand from there.
- Step 1 — AI Readiness Scan: short assessment of your data and processes.
- Step 2 — Use-case workshop: one concrete problem as starting point.
- Step 3 — Pilot in four to six weeks inside a single department.
- Step 4 — Evaluation and staged roll-out across the organisation.
- Step 5 — Ongoing operations, updates and new use cases.
