Private AI vs
Microsoft Copilot.
A detailed comparison between HTX's private enterprise AI and Microsoft's ecosystem-integrated assistant. Same promises, opposite control models.
Why European businesses are questioning Microsoft Copilot.
Microsoft Copilot for Microsoft 365 launched in November 2023 as Microsoft's answer to enterprise AI demand. The idea is powerful: an AI assistant integrated directly into Word, Excel, Teams, Outlook, and PowerPoint. For organisations already deep in the Microsoft ecosystem, it seems like the natural choice.
But convenience comes with hidden costs. Copilot works exclusively within the Microsoft ecosystem. Your data is processed in Azure cloud infrastructure. The $30/user/month model scales linearly with adoption. And you're locked into a single vendor for AI models, pricing, and feature roadmap.
For European companies handling sensitive data — intellectual property, healthcare data, financial information — the question has become: is the convenience of Microsoft integration worth the price of total dependence on a single vendor?
This comparison analyses the facts. We built ORCA, so we're transparent about our perspective — but we recognise Copilot's strengths where they exist.
Feature comparison at a glance.
This table covers the dimensions that matter most for European businesses evaluating private AI versus Microsoft Copilot.
| Dimension | Private AI (HTX ORCA) | Microsoft Copilot |
|---|---|---|
| Data location | Your infrastructure (on-premise or EU cloud) | Microsoft Cloud (Azure, various data centres) |
| GDPR compliance | Compliant by architecture — no international data transfer | Microsoft DPA and contractual clauses; possible non-EU transfers |
| Integrations | Any system: ERP, CRM, databases, SharePoint, legacy systems via MANTA | Microsoft 365 ecosystem only (Word, Excel, Teams, Outlook, PowerPoint) |
| Pricing model | Fixed infrastructure — unlimited users | ~$30/user/month (on top of M365 licence) |
| Cost at 50 users | Fixed (typically lower than per-user equivalent) | ~$18,000/year (Copilot only, excludes M365 licence) |
| AI models | Multi-model: Mistral, LLaMA, DeepSeek, Qwen — choose per task | GPT-4 only (single OpenAI model via Microsoft) |
| Customisation | Fully customisable: prompts, workflows, UI, custom integrations | Limited to Copilot parameters and Microsoft tools |
| Vendor lock-in | None — open-source models, standard formats, your infrastructure | High — tied to Microsoft ecosystem and pricing |
| Offline capability | Yes — full offline operation with on-premise deployment | No — requires internet connection and Microsoft cloud services |
| Document RAG | Advanced RAG with citations, configurable chunking, any format | Search across Microsoft 365 documents, limited retrieval control |
| Database queries | Native NL2SQL via MANTA — query any database in natural language | Limited to Excel and structured data in Microsoft 365 |
| Admin controls | Full: user management, audit logs, policies, granular access | Via Microsoft 365 Admin Centre, tied to Microsoft licences |
Vendor lock-in: the hidden risk.
Microsoft Copilot works only inside Microsoft 365. If your business uses non-Microsoft systems — SAP, Salesforce, PostgreSQL databases, custom ERPs, legacy systems — Copilot cannot access them directly. This creates a subtle but constant pressure toward full adoption of the Microsoft ecosystem.
With private AI, the paradigm is reversed. ORCA connects to any system through open connectors and MANTA (NL2SQL). Whether you have SAP ERP, Salesforce CRM, a PostgreSQL database, or an internally-developed management system, ORCA integrates without forcing you to change your infrastructure.
There's also pricing risk. Microsoft has already increased Copilot costs and can continue to do so. With a fixed infrastructure model, your costs are predictable and under your control.
Total cost of ownership: the real analysis.
Microsoft Copilot looks affordable at first glance: $30 per user per month. But the real cost includes the underlying Microsoft 365 licence (which you may or may not already have), plus Copilot itself.
For a 50-user organisation over 3 years:
Microsoft Copilot
50 users x $30/month = $1,500/month = $54,000 over 3 years (Copilot only). Add the M365 E3/E5 licence and costs rise further. Pricing can change at Microsoft's discretion. 100 users = $108,000 over 3 years.
Private AI (ORCA)
Upfront infrastructure investment + fixed operational costs. Unlimited users on the same infrastructure. Per-user cost decreases with scale. At 50+ users, the 3-year TCO is typically lower than Copilot, with the added benefit of data sovereignty.
When to choose what.
We believe in helping you make the right decision. Here's our honest assessment:
Choose Private AI when
Data sovereignty and control are priorities. You're in a regulated industry, use non-Microsoft systems, want to avoid vendor lock-in, need offline capability, or have more than 25-30 users. You want multi-model flexibility, integration with any system, and predictable costs.
Choose Microsoft Copilot when
You're fully invested in Microsoft 365. You have a small team (under 20 users), all your work happens in Word, Excel, Teams, and Outlook, you don't have strict data sovereignty requirements, and you want instant activation without infrastructure setup.

Frequently asked questions
Can private AI do everything Microsoft Copilot does?
For core capabilities — chat, document Q&A, text generation, data analysis — yes. ORCA provides the same conversational and document intelligence capabilities. The main difference is that Copilot has native integration with Microsoft 365, while ORCA integrates with any system through open connectors and MANTA (NL2SQL).
How much does Microsoft Copilot cost compared to a private solution?
Microsoft Copilot for Microsoft 365 costs approximately $30 per user per month, on top of your existing Microsoft 365 licence. For 50 users, that's roughly $18,000/year for Copilot alone. A private solution like ORCA uses a fixed infrastructure model with unlimited users, becoming more cost-effective from around 25-30 users.
Can I use Microsoft Copilot offline?
No. Microsoft Copilot requires an active internet connection and access to Microsoft cloud services. ORCA with on-premise deployment works fully offline, ideal for air-gapped environments, manufacturing floors, or locations with limited connectivity.
Is my data safe with Microsoft Copilot?
Microsoft processes data in Azure infrastructure and offers contractual guarantees and security certifications. However, data may transit through non-EU data centres for specific features. With private AI, data never leaves your infrastructure — eliminating all transfer risks.
Can I migrate from Microsoft Copilot to a private AI solution?
Yes. HTX provides a structured migration path. Conversational and document workflows are similar, so end-user retraining is minimal. The typical migration takes 2-4 weeks including pilot testing on your real use cases.
