The sovereign ChatGPT alternative for your business
ChatGPT is a great product — but your company data deserves better than transiting through the servers of a US company subject to the Cloud Act. Eridia gives you the same models (GPT included), plus all the others, deployed on your infrastructure: the power of AI, with sovereignty on top.
Why companies look for an alternative
The Cloud Act applies, even with EU hosting
OpenAI and Microsoft are US companies: the Cloud Act lets US authorities compel access to the data they process, wherever it is hosted. For regulated industries, that is a blocker.
Your prompts contain your trade secrets
Contracts, strategy, source code, client data: every prompt sent to a cloud AI exposes sensitive information to a third party, with limited traceability on the company side.
One vendor, stacking costs
ChatGPT Enterprise only gives access to OpenAI models. To also get Claude, Gemini or Mistral, you must multiply subscriptions — scattered budget, scattered data.
Eridia vs ChatGPT Enterprise vs Microsoft Copilot
The criteria that matter for a European company.
| Eridia | ChatGPT Enterprise | Microsoft Copilot | |
|---|---|---|---|
| Where your data lives | Your servers or EU private cloud | OpenAI cloud (US company) | Microsoft cloud (US company) |
| Cloud Act exposure | None on-premise | Yes | Yes |
| On-premise / air-gapped deployment | Turnkey, in 1 day | Not possible | Not possible |
| Available AI models | All: GPT, Claude, Gemini, Mistral, DeepSeek… | OpenAI only | OpenAI via Microsoft |
| Local open-source models | Yes, on your hardware | No | No |
| Connection to your tools (Drive, Notion, Slack…) | Native, local indexing | Partial | Microsoft ecosystem |
| Meeting transcription | Included, unlimited from the Pro plan | Not included | Via Teams only |
| Indicative price per user | €17–31/month, all models included | ~$55–60/month | ~€30/month (+ 365 license) |
Public prices observed 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.
