European ChatGPT alternative for business: what to check before you buy

As of 11 October 2026

A European head office does not make an AI assistant European on its own. Look at four things in the contract and the documentation: where your data is stored, where the model actually runs, which sub-processors sit in between, and which law each of those parties answers to. A US product can be set up to be European on several of these points, and a European one can still send some data elsewhere.

Nobody gets ranked here. The right choice depends on your data and the models your people need.

Seven questions behind the word “European”

Layer What to ask Where the answer is
Contracting party Which entity signs, which law governs, which courts decide? Terms of service or master agreement
Storage Where are conversations and files stored, backups included? What sits elsewhere, user logins for instance? Data processing agreement, residency documentation
Inference In which country are the GPUs that process your prompts? Product documentation, DPA
Sub-processors Who hosts the application, who runs the model, who provides web search? Sub-processor list (Art. 28(2) GDPR)
Foreign access Is any party in that chain subject to US jurisdiction? Your legal team, a written answer from the vendor
Training Are your prompts used to train models? Does it depend on the plan? Privacy notices, help centre
Model choice One model maker or several? Can you block models for certain work? Product documentation

Documents answer the first four rows. The fifth is a legal question.

Storage and inference are separate questions

OpenAI's own help centre shows how precise you need to be. New eligible ChatGPT Enterprise customers can choose storage in the Europe region, which covers the EEA and Switzerland. Inference residency builds on that and keeps GPU processing in Europe as well. OpenAI is candid about the limits: “Non-GPU processing may still occur globally”, and authentication, routing and analytics may take place outside the selected region. User logins and billing information may be stored outside the region, as may workspace metadata and anything that goes through external integrations such as web search. According to the pricing table, ChatGPT Business does not include data residency.

Ask European vendors for the same level of detail. Mistral AI, headquartered in Paris, says in its help centre that data is hosted in the EU by default. Depending on the feature, data can be transferred temporarily to sub-processors outside the EU, and Mistral lists their locations in its Trust Center. That is openly documented. It shows that “a European vendor” and “processing only in Europe” are two different claims.

What the CLOUD Act and FISA say

The CLOUD Act of 2018 added one sentence to the Stored Communications Act, now 18 U.S.C. § 2713. A provider must disclose content and records in its possession, custody or control regardless of whether they are located inside or outside the United States. A server in Frankfurt or Dublin does not settle that by itself.

What counts is whether a provider is subject to US jurisdiction. The US Department of Justice, in its April 2019 white paper, says that jurisdiction is not limited to US corporations, but that it is not unlimited either, and that the analysis is highly fact-dependent. On the European side, Article 48 of the EU GDPR applies. A third-country court judgment or authority decision requiring personal data to be handed over can only be recognised or enforced if it rests on an international agreement, such as a mutual legal assistance treaty.

For UK readers, the Department of Justice lists a US-UK agreement on access to electronic data, from October 2019, among its CLOUD Act resources.

Lawyers will also raise Section 702 of the Foreign Intelligence Surveillance Act (FISA), 50 U.S.C. § 1881a. For foreign intelligence, the Attorney General and the Director of National Intelligence may authorise, for up to a year, the targeting of persons reasonably believed to be outside the United States. They can direct an “electronic communication service provider” in writing to assist, in secret. Under § 1881(b)(4) that term covers remote computing services, so cloud providers too.

Congress extended 702 by two years in April 2024 with the Reforming Intelligence and Securing America Act, then twice in April 2026, finally to 12 June 2026 (Pub. L. 119-87). No further extension had been enacted by 11 October 2026. Authorisations and directives already issued stay in effect until they expire (§ 404(b), FISA Amendments Act of 2008), so record in your transfer impact assessment which legal position you assumed.

Section 702 is one reason the Court of Justice struck down the Privacy Shield in Schrems II (C-311/18, 16 July 2020), finding programmes based on it not limited to what is strictly necessary. Its successor, the EU-US Data Privacy Framework of 10 July 2023 (Decision (EU) 2023/1795), survived an action at the General Court on 3 September 2025 (T-553/23); an appeal has been pending since 31 October 2025 (C-703/25 P).

We do not judge here whether any provider falls under these laws, ourselves included. That would be legal advice resting on facts only each provider knows. Put the question in writing for every party in the chain: the contracting entity, the hosting company, the model operator and the web search provider. Ask too how the vendor would tell you about a disclosure request where it may.

Reading the sub-processor list

Article 28(2) GDPR allows a general authorisation for further processors; the processor must then inform you of any intended change and give you the chance to object. With AI services the list often names the cloud under the application, the model providers and web search. It tells you more about how European a service is than any homepage. Check that every entry has a location and how much notice you get before a change.

Training and model choice

Whether your prompts end up in training can depend on the plan. OpenAI says it does not use data from ChatGPT Business or Enterprise for training by default. Mistral's Vibe, formerly Le Chat, uses inputs and outputs for training by default until you opt out, according to its help centre; Enterprise customers are opted out from the start, and a thumbs-up or thumbs-down rating with a comment may be used on any plan. Check the plan you will actually buy, and set the switch before the first real prompt.

For model choice there are two approaches. A model maker offers its assistant with its own models, as ChatGPT and Vibe do. A workspace brings models from several makers together and lets you decide which model may see which data. The first is simpler; the second helps if another model later does your work better. For work that must not reach any external model provider at all, you need a model the vendor runs itself, or one you run in house.

Checklist for your shortlist

  1. Contracting entity, governing law and courts taken from the contract.
  2. Storage location in writing, including the data allowed to sit elsewhere (logins, metadata, billing).
  3. Inference location known for every model you allow, web search and integrations included.
  4. Sub-processor list with locations in hand; notice period and right to object written into the DPA.
  5. The US jurisdiction question asked for every party in the chain and assessed by your legal team.
  6. Training on your data excluded for your plan, with the setting documented.
  7. Work that must not reach an external model identified and blocked technically.
  8. Handling of personal data before external models settled, for example by pseudonymisation.
  9. Exit planned: export in open formats, deletion after the contract ends.
  10. Interface available in the languages your staff work in.
  11. A pilot with real tasks, with your data protection officer involved from day one.

When ChatGPT Enterprise is the better choice

If your team mainly wants OpenAI models, going direct is often right. For eligible new customers, ChatGPT Enterprise offers storage and inference in Europe, OpenAI does not train on Enterprise data by default, and the pricing table lists the Compliance API and ISO 27001, 27017, 27018 and 27701 for Enterprise. Two questions stay open: the data OpenAI says may sit outside the region, and jurisdiction, which is for your counsel. If you want models straight from a European model maker, look at Mistral.

How Myra AI Workspace answers the seven questions

The contracting party is Myra Security GmbH in Munich. On foreign access: Myra Security GmbH has no US parent and no US subsidiary. The legal assessment is for your counsel. Myra models run on Myra's own EU infrastructure, and the model picker labels them “Hosted by Myra (Germany)”. AI Workspace runs on Myra infrastructure that holds a BSI C5 Type 2 attestation; C5 is the cloud security catalogue of Germany's Federal Office for Information Security, and the attestation covers the infrastructure, not the application itself. Myra does not use customer data to train AI models.

Your administrator can allow external models, for example from Anthropic or Google, under their makers' own terms. EU routing can be enforced per gateway or for the whole organisation, and requests to providers outside the EU are then refused before they are sent. It is off out of the box. In a project set to the “Local only” access tier, the model picker offers Myra models alone; cloud models, web search and external tools are blocked there. On paid self-service plans, the Myra-hosted models, and so any “Local only” project, require the “EU-Gov” add-on. When a request goes to an external model, Myra replaces personal data with placeholders first and restores the original values in the answer. This is available in every plan, and under the GDPR it remains pseudonymisation.

Under our DPA, Myra announces new sub-processors at least 30 days ahead, and you can object.

Optionally, Myra stores your data in Switzerland, with inference of the Myra models on Myra's EU infrastructure. Hosting in your country is possible on request, as is an on-premises deployment. The interface is available in English and German only. More on the product: Myra AI Workspace.

Frequently asked questions

Is there a European version of ChatGPT?

Partly. According to OpenAI, new eligible ChatGPT Enterprise customers can have content stored in the Europe region (EEA plus Switzerland) and model inference run there too. Companies based in Europe offer assistants as well, such as Mistral's Vibe, Langdock, meinGPT and Myra AI Workspace.

Does a data centre in the EU protect against the CLOUD Act?

Location alone does not settle it. Under 18 U.S.C. § 2713 a provider must disclose data under its control even when it sits outside the United States. Whether the provider is subject to US jurisdiction is a question for your lawyers, about every party in the chain.

Can I use Claude or Gemini models in Myra AI Workspace?

Yes, once your administrator allows them; the providers' own terms apply to those models. With privacy switched on, Myra replaces personal data with placeholders before the text is sent.
