ChatGPT alternatives from Europe: Vibe, Lumo and Euria compared
Mistral's Vibe, Proton's Lumo and Infomaniak's Euria side by side: who owns them, where your chats go, whether they train on them, and what they cost.
Three European AI assistants offer ChatGPT's everyday features, chat, web search and file uploads, and they differ most where you can't see it. Lumo, from Proton, and Euria, from Infomaniak, run open models on their own servers and don't train on your chats. Vibe, from Mistral, has the most features of the three, but like ChatGPT it trains on your chats unless you opt out, and some of its features go through US providers.
Vibe is the new name for Le Chat: Mistral renamed it in August 2026. Same address, same login, same conversations.
Below, each one gets the three answers from Is it really European?, plus what it costs and what it does. ChatGPT is in the last column for reference.

Prices and terms as published on 7 November 2026.
Owned: who controls them
Vibe: Unknown. Mistral AI is a French company with no parent, funded by investors in Europe, the US and Asia. Its three founders hold shares with extra votes, and ActuIA reported that they kept more than half of the votes after the 2025 round. Mistral has not said how its €3 billion round of September 2026, led by Samsung Electronics, changed that, so nobody outside the company can say who controls it today.
Lumo: Switzerland (Europe, not EU). Proton AG is based in Geneva, and its main shareholder is the Proton Foundation, a Swiss non-profit. In late October, 404 Media reported that Proton's CEO was pushing staff to build with AI despite their security concerns, then called off company-wide interviews about how they use it. The part of the reporting we could read doesn't mention Lumo.
Euria: Switzerland (Europe, not EU). Infomaniak is based in Geneva, and the Infomaniak Foundation holds the majority of the votes.
ChatGPT: United States. OpenAI Group PBC, the company behind ChatGPT, is controlled by the OpenAI Foundation, a US non-profit. For people in the EU, the company responsible for your data is OpenAI Ireland Limited in Dublin.
Where your chats go
Training. Two of the four learn from your chats by default.
- Vibe: "Input and output data are used by default to train our artificial intelligence models, unless you opt out" (Mistral). To opt out, turn off "Allow your interactions to be used to train our models" under Vibe's privacy settings, or "Enable data sharing" in the app (how).
- ChatGPT: "On personal workspaces with ChatGPT Free, Plus, or Pro, data sharing is enabled by default" (OpenAI). To opt out, go to Settings, Data controls, and turn off "Improve the model for everyone". Voice mode has its own setting.
- Lumo: "Lumo doesn't use your chats to train the AI models" (Proton). The one exception is feedback you choose to send about the Apertus model, which Proton may share with the Swiss universities that build it.
- Euria: Infomaniak "formally undertakes never to use your data, files or conversations to train or refine its artificial intelligence models" (Infomaniak).
On both Vibe and ChatGPT, rating an answer with a thumbs up or down can still send that conversation to training, even after you opt out.
Servers. Vibe keeps your data "in the European Union" by default (Mistral). Its list of sub-processors shows where: Microsoft's data centres in Sweden and Norway, Google's in the Netherlands and Belgium, Mistral's own in France, and those of CoreWeave, a US company that runs AI models for Mistral, somewhere in the EEA. Two features leave Europe: web search goes through Brave and image generation through Black Forest Labs, both listed in the United States. Coding in the browser also runs partly on hosts listed as "Worldwide" and on OVHcloud in the US. That is why Vibe's Hosted answer is Mixed.
Lumo "runs on servers controlled entirely by Proton in Europe" (Proton); Proton doesn't say which countries. Your prompt is encrypted so that only Lumo's GPU servers can read it, and saved chats are encrypted so that Proton can't. Proton's help pages say web search is off until you turn it on, but in our guest test it was already on and Lumo searched by itself. When it searches, a simplified version of your question goes to search partners Proton doesn't name.
Euria's processing and storage happen "exclusively in Infomaniak's data centers in Switzerland, with no external service providers or data transfer abroad" (Infomaniak).
ChatGPT processes your data "on servers located outside of the EEA, Switzerland and the UK", including in the United States (OpenAI). Data residency in Europe is only for business, education and API customers, not personal accounts.
Lumo and Euria both run open models. Lumo uses Qwen 3.5 and GLM 5.3, first published by Chinese labs, and the Swiss model Apertus (Proton). Euria offers Apertus too and says its models are open source, but Infomaniak's help pages don't list the others. An open model running on your provider's servers sends nothing to the lab that made it.
What you get for the money
Vibe has the most features: web search, file uploads (up to 15 GB on Pro), image generation and editing, voice mode, projects, connectors to other apps, scheduled tasks and a coding mode, on the web and in apps for iPhone and Android (pricing). The free plan needs a Mistral account and limits messages, searches and images. Pro costs €14.99 a month before VAT, which comes to €17.84 in Germany and €17.99 in France; students pay €5.99 before VAT.
Lumo does web search, file uploads, image generation and editing, dictation, memory and projects, on the web and in apps for iPhone and Android (Proton). The free plan limits messages and image generation and keeps chats for 7 days. Lumo Plus costs €12.99 a month, or €119.88 a year (€9.99 a month) (pricing).
Euria does web search, file uploads (documents, images, audio and video), dictation and transcription, and projects, on the web and in apps for iPhone and Android (Infomaniak). Infomaniak doesn't list image generation. You can use it free without an Infomaniak account; messages are capped over a rolling 24 hours, but Infomaniak doesn't publish the number. The paid my kSuite+ plan, from CHF 19 a year including VAT, adds unlimited projects (prices).
ChatGPT costs €8 a month for Go, which may show ads, and €23 for Plus (pricing).
How they did on five everyday tasks
On 2 November 2026 we gave Lumo and Euria the same five tasks, signed out, each on its default model (Lumo 2.0 Max and Euria's Fast). Vibe asks you to sign in before it answers, so it isn't in this round yet.
| Task | Lumo | Euria |
|---|---|---|
| Summarise a 640-word article in three bullet points | Accurate, but two of the three bullets went to the opening example | Accurate, and covered the whole article |
| Write a short, polite email to a landlord in German | Correct and formal, longer than asked, plus tips on tenants' rights | Correct and formal, short, with a subject line |
| Which company led Mistral's September 2026 round, and how much? | Right (Samsung Electronics, €3 billion), after searching the web by itself | Right, after searching the web by itself |
| An Excel formula to add column B where column A says "Paid" | Right: =SUMIF(A:A,"Paid",B:B), with an explanation | Right: the same formula |
| Create an image of a red bicycle against a white wall | Made one | Can't: "I can't generate or modify images" |
Neither got a fact wrong. Lumo tends to give more than you asked for; Euria keeps to the question.
Moving your history from ChatGPT
None of the three can import your ChatGPT history. You can still take a copy with you:
- In ChatGPT, go to Settings, Data controls, Export data. A download link arrives by email; it can take up to 7 days and stops working after 24 hours (OpenAI).
- Keep the ZIP: it holds every chat.
- Copy what you rely on, such as your custom instructions, into a project or memory in the new assistant.
Leaving again works differently on each. Lumo exports one conversation at a time, as JSON or Markdown, and images may be left out (Proton). Mistral's help centre describes an export tool for your Vibe data, but its pricing table lists data export only on Team and Enterprise plans. Infomaniak doesn't document an export for Euria.
Also European, but not in the table
- Ecosia's AI chat comes from a Berlin company, but it forwards your questions to Mistral and is still in beta for some users (Ecosia).
- Swisscom myAI is Swiss, but it launched on Anthropic's Claude, run on Amazon's cloud (Swisscom), and needs a Swisscom login.
- Mammouth is a Paris company that sells access to US models such as GPT, Claude and Gemini (pricing): a European company, with your chats going to American providers.
- Aleph Alpha (Heidelberg) and Langdock (Berlin) sell to businesses, not to individuals. Aleph Alpha signed a merger agreement with Canada's Cohere in September and will take Cohere's name once regulators approve.
HuggingChat and Kagi's assistant come up in the same lists, but both companies are American: Hugging Face and Kagi are Delaware corporations.
Which one fits
There is no single winner; it depends on what you weigh most.
- Nothing trained, nothing outside Europe: Lumo or Euria. Both are Swiss, so both carry the "Europe, not EU" label.
- No account at all: Euria, or Lumo as a guest.
- The most features, from a company based in the EU: Vibe, once you have turned off training, and knowing that its web search and images go through US providers and that its owner is unknown.
