Comparison
The sovereign Microsoft Copilot alternative
Copilot is integrated with Microsoft 365. Eridia offers a separate platform connected to your tools, with models run in the EU and an option to deploy on your infrastructure.
Why companies look for a Copilot alternative
Lock-in to the Microsoft ecosystem
Copilot requires Microsoft 365 licenses and shines only inside Word, Excel, Teams and Outlook. Your non-Microsoft tools — Notion, Slack, Google Drive, your business applications — stay out of scope.
A single model vendor
Copilot runs on OpenAI models served by Microsoft. You cannot pick Claude for contract analysis or Mistral for local processing: you inherit Microsoft's choice, at Microsoft's price.
The Cloud Act, same as ChatGPT
Microsoft is a US company: your prompts, documents and data indexed by Copilot remain legally accessible to US authorities, even when hosted in a European Azure region.
Eridia vs Microsoft 365 Copilot vs ChatGPT Enterprise
The criteria that matter for a European company.
| Eridia | Microsoft 365 Copilot | ChatGPT Enterprise | |
|---|---|---|---|
| Where your data lives | Your servers or EU private cloud | Microsoft cloud (US company) | OpenAI cloud (US company) |
| Cloud Act exposure | Isolated setup available | Yes | Yes |
| Self-hosting / air-gapped | Turnkey, in 1 day | Not possible | Not possible |
| Available AI models | Models run in the EU or locally | OpenAI via Microsoft | OpenAI only |
| Works outside the Microsoft ecosystem | Yes: Drive, Notion, Slack, business tools… | No, built for Microsoft 365 | Partially |
| Desktop app (Cowork and Code modes) | Yes, data processed inside your perimeter | Embedded in Office (US cloud) | App available (US cloud) |
| Secure agents and automations | Yes, with human validation on outbound actions | Copilot Studio (Microsoft cloud) | OpenAI cloud agents |
| Meeting transcription | Included — Teams, Meet, Zoom or in person | Teams only | Not included |
Comparison made in good faith at publication date; vendor offers evolve. The structural point does not: a US company remains subject to the Cloud Act, wherever the data is hosted.
What Eridia actually does for your teams
Much more than chat: a complete workspace with multiple AI models run in the EU or locally.
Cowork mode — desktop app
AI works alongside you right on your machine: writing, document analysis, spreadsheets, presentations — on your real files, not in an isolated tab.
Code mode
Code generation and execution in a secure sandbox: scripts, data analysis, prototypes — with nothing extra to install.
AI agents and automations
Build agents that run your recurring processes autonomously and securely, with human validation at critical steps.
Meeting transcription
Your meetings transcribed, summarized and ready for AI. On-premise, the audio never leaves your infrastructure.
Your documents, connected
Drive, Notion, Slack, SharePoint... your data is indexed and searchable with role-based access control. Optional integrations are covered in our privacy policy.
Turnkey self-hosting
The same platform, deployed on your servers or managed in the EU. Your content remains hosted in the EU.
What you gain by switching to Eridia
- Multiple models run in the EU or on your infrastructure, in one interface
- Your tools connected beyond Microsoft: Google Drive, Notion, Slack, business applications
- A desktop app with Cowork mode (assisted work on your files) and Code mode, data inside your perimeter
- Autonomous yet secure agents and automations: a human validates every outbound action
- Real self-hosting: your servers, your private cloud or a French cloud — no Azure dependency
- An offer independent of your office suite license
