Best EU AI Chat Alternatives to Mistral Vibe (Le Chat) in 2026
Le Chat is now Vibe. Same login, same address at chat.mistral.ai, more of an agent than a chat. If you want an EU AI Chat that is not Mistral’s, these three are worth looking at:
TLDR: Stay on Vibe if you want connectors, agents and the richest feature set. Switch to DentroChat if you want no US company in the chain, including payments. Stay inside Proton (Lumo) if you already live there and can wait for AI answers. Pick Euria if cheap and Swiss is the whole point.
Why look for an EU AI Chat alternative to Mistral Vibe?
Mistral is Europe’s strongest model lab, and Vibe is the most capable consumer product we got. Still, people leave it, and usually for one of three reasons:
-
The infrastructure. Vibe calls itself European, and the company is. However, the subprocessor list is not. Inference runs on Google Cloud, and they use also Cloudflare, Netlify, Vercel and Vanta. Their billing goes through Stripe. A longer look at which of the two actually keeps data away from US companies is already on this site.
-
The answers. While Vibe is fast and well structured, it’s answers are sometimes lackluster. In our example, it labelled December 2024 electricity prices as the latest Eurostat data, even though we have August 2026. Eurostat had published the second half of 2025 in May.
-
The product itself. In May 2026 Le Chat became a unified agent powerhouse with Work, Code and Chat modes. While this is really good workspace, it’s a worse simple EU AI Chat if you just wanted to ask a question.
None of that makes Vibe a bad product. Feature wise it wins, and it’s not even close. Read-aloud, Gmail and Atlassian connectors, projects, a library, background agents, a native app and a proper free tier: nobody else here has that combination. The question is whether you need what it offers, or need better answers, and actual European sovereignity.
How these EU AI Chats were compared
For each EU AI Chat, we gave it the same prompt. We used each app on its highest reasoning setting, e.g. “Max”, “Thinking”, “Expert” etc. The prompt was:
Using current sources, do all of the following:
- Find the most recent average household electricity price (€ per kWh, including
taxes and levies) for Germany, Sweden, and Poland. For each, give the
figure, the reference period, and a source link.
- For a household using 3,500 kWh per year, calculate the annual bill in each
country. Show your arithmetic. Then state how much more expensive the most
expensive country is than the cheapest, as a percentage to one decimal place.
- Produce a downloadable bar chart of the four annual bills, plus a spreadsheet
file containing the underlying table.
- Summarise the key consumer-protection obligations in "Directive (EU) 2026/1174
on residential energy price transparency" and cite the relevant article numbers.
- Format a final markdown tableThe mentioned EU directive does not exist, and was a trick question to see how each EU AI Chat responds ;-)
The number 1174 belongs to a sanctions regulation with two articles and have nothing to do with energy.
The real prices, checked against Eurostat dataset nrg_pc_204 for the second half of 2025, band DC, all taxes included, are these:
| Country | €/kWh | Annual bill at 3,500 kWh |
|---|---|---|
| Germany | 0.3869 | €1,354.15 |
| Sweden | 0.2711 | €948.85 |
| Poland | 0.2709 | €948.15 |
So Germany is 42.8% more expensive than Poland. The results were obviously a hands-on snapshot, and not a lab benchmark, but they give a good overview.
Who got what right
| Result | Vibe | DentroChat | Lumo | Euria |
|---|---|---|---|---|
| Headline figure (true: 42.8%) | 76.2% | 42.8% | 51.2% | 295.4% |
| Refused the fake EU directive | Yes | Yes | Yes, and found the real regulation | Yes |
| Bar chart | Yes, download to view | Yes, in the chat | Yes, in the chat | No |
| Spreadsheet file | Yes | Yes | No (CSV text to copy) | No |
| Time to answer | ~1 minute | ~1 minute | ~15 minutes | ~1 minute |
Vibe handled the fake directive well. It said no such document could be found, invited a correction if a different reference was meant, and offered a real substitute: Articles 21, 22 and 24 of Directive (EU) 2023/1791, which is the recognised consumer-provisions cluster of that directive. It also got the 24-hour supplier-switching rule right, which e.g. DentroChat quoted wrong (still quoted the old three-week version). But then the data went wrong. Sweden and Poland were taken from December 2024 and labelled as the latest Eurostat figures. Of course they aren’t: Eurostat published the second half of 2025 in May 2026. Also, Germany was taken from a different source, BDEW, from April 2026, so the comparison sat on numbers that do not belong in the same table. That is how Vibe arrived at 76.2% instead of 42.8%. The answer was well structured, and came with both a chart and a spreadsheet. Overall, great feature set, and stale data is forgivable. But calling it current is not, and mixing up different time frames makes no sense.
DentroChat was the only one that went to the official source. It queried the Eurostat API directly, landed on the right dataset and the right consumption band, and came back with every figure matching the table above, including the 42.8% headline. It also refused to invent the fake directive, said it would rather flag the gap than guess, and still delivered a bar chart you can see in the chat plus a real spreadsheet, in about a minute. However, DentroChat also mixed up 2 of 5 article numbers when it pointed at the real Electricity Directive 2019/944. The articles exist, the numbering is just wrong, which is a different kind of mistake from inventing law, but it is still a slip. Overall, the best performing AI EU Chat on the question, fast and accurate.
Lumo won the hardest part of the prompt. It found the real Implementing Regulation (EU) 2026/1174, pointed out that it is a regulation rather than a directive and has nothing to do with energy prices. No other EU AI Chat managed that. It also wrote the clearest account of its own limits: it said which figures came from an older half-year and why the newer ones were not in the text it could reach, and it named the Eurostat dataset. Germany at €0.3869 was exact. Sweden and Poland were correct H1 2025 values rather than H2, which is why the headline came out at 51.2% instead of 42.8%. It disclosed the mismatch instead of hiding it. The cost was time. Lumo took roughly fifteen minutes and made 27 tool calls (19 searches and 8 page extractions) to get there. It drew a good chart in the conversation, but it could not attach a spreadsheet, only a block of CSV text to copy and save yourself. Overall, solid, but slow and not the right number for the electricity question.
Euria was the most honest about what it could not do, and then the least useful on the thing it could. It refused the fake directive and would not invent article numbers. When Poland did not turn up, it just said clearly: “I cannot fulfill the request for Poland without hallucinating.” It also said upfront that it cannot produce charts or spreadsheets. On Germany it even cross-checked two conflicting figures and picked the right one. Then it reported Sweden at €0.0970 per kWh against a true €0.271, which is 64% too low, and stated it as confirmed. But that number is Sweden’s industrial, non-household price from the same Eurostat table. While Lumo quoted it correctly as industrial, Euria put it in the household column. Funnily, the warning was sitting in its own answer already, which gave the EU average as €0.2896, so Sweden at a third of that should have looked impossible. With no Poland and a broken Sweden, it reduced the task to Germany versus Sweden and produced 295.4%, wrong by a factor of seven. The reply was also messy: the model’s private reasoning leaked into the user-facing text, so you read it arguing with itself (“Wait, I need to be precise”) on the way to the number. Overall good for simple tasks, but need to be careful with complicated ones.
So: DentroChat got the official numbers and the files, and missed the gold-standard answer on the trick question. Lumo got the trick question and paid for it with a quarter of an hour. Vibe looked the most polished and used the stalest data. Euria refused to lie about Poland and then wrecked Sweden.
The shortlist
This is ranked for someone leaving Vibe:
- DentroChat is the closest Vibe alternative if you still want files and code, and it is the only one of the three whose published stack has no US companies at all, payments included. In the test it was also the only one that hit 42.8% exactly, because it went to the Eurostat API instead of outdated news summaries.
- Lumo by Proton is the one to pick if you already trust Proton and would rather wait than be misled. It was the only EU AI Chat here that caught the real Regulation 2026/1174. The trade-off is the wait, the missing files, and billing that still goes through US companies.
- Euria by Infomaniak is the one to pick if €19 a year and Swiss datacentres are what you are optimising for. It has the thinnest feature set of the three, and in the test it produced the worst number. For drafting and everyday writing it is still remarkable value.
Core chat features
These are the four EU AI Chats as they stood in August 2026. Everyone here can search the web, upload a document and understand an image you attach:
| Feature | Vibe | DentroChat | Lumo | Euria |
|---|---|---|---|---|
| Web search | Yes | Yes | Yes | Yes |
| Image generation | Yes | Yes | Yes | No |
| Image editing | Yes | Yes | Yes | No |
| Voice input (dictation) | Yes | Yes | No | Yes |
| Read answers aloud | Yes | No | No | No |
| Memory across chats | Yes | Yes | Yes | No |
| Edit and branch a message | Yes | Yes | Yes | Yes |
| Renders maths properly | Yes | Yes | No | No |
| Mobile app | Yes | No (only PWA) | Yes | Yes |
Read-aloud is the rarest row: only Vibe will speak its answers back to you. Euria cannot generate or edit images, and it is also the only one without memory, so it will not remember you across chats. Lumo and Euria can both emit LaTeX, but they cannot render it, which means a calculation shows up as a wall of backslashes instead of a readable formula. DentroChat is the one without a native iOS or Android app. You can install the website to your home screen as a web app, and that works, but it is not the same as opening a store app.
Files and teamwork
While uploading a file works across all EU AI Chats, creating files doesn’t:
| Feature | Vibe | DentroChat | Lumo | Euria |
|---|---|---|---|---|
| Upload files and documents | Yes | Yes | Yes | Yes |
| Create downloadable files | Yes | Yes | No | No |
| Run code | Yes | Yes | No | No |
| Organise chats into projects | Yes | No | Yes | Yes |
| Share a chat by link | Yes | Yes | No | Yes |
| Agents and background tasks | Yes | No | No | No |
| Connectors | Gmail, Atlassian, Notion and more | No | Proton Drive | kDrive |
| Export your data in the app | Yes | Yes | No | No |
Only Vibe and DentroChat can run code and hand you back a real file, which is why they were the only two that produced an actual spreadsheet in the test. Lumo and Euria will happily read a PDF you upload, but they won’t give you a chart or an .xlsx file.
DentroChat is the only one here without projects or folders. If you are coming from Vibe’s projects and library, you might notice it.
Connectors are the widest gap in this whole comparison. Vibe is the only EU AI Chat with real third-party integrations, the kind that reach Gmail, Atlassian, Notion and similar tools. Lumo connects to Proton Drive, Euria to Infomaniak’s kDrive, and DentroChat to neither. If the reason you use Vibe is that it can touch the rest of your work stack, none of the alternatives replace that unfortunately.
Sovereignty and control
All four keep the chat servers in Europe, so “hosted in the EU” on its own separates nobody. The useful question is whether a US company is involved in handling your data:
| Vibe | DentroChat | Lumo | Euria | |
|---|---|---|---|---|
| Chat servers in | EU | EU + Swiss | EU + Swiss | Swiss only |
| Payment provider based in | US | EU | US | UK or US |
| No US subprocessors in the chat | No | Yes | Yes | Yes |
| No US subprocessors anywhere | No | Yes | No | No |
| Ghost / incognito mode | Yes | Yes | Yes | Yes |
| Auto-delete old chats | No | Yes | No | No |
| Interface languages | 10 | 17 | 35 | 7 |
Vibe fails the row “no US subprocessors in the chat”, because inference runs on Google Cloud. The machines can still sit in Ireland, but if the company that runs them is US-American, it falls under the US CLOUD Act. DentroChat, Lumo and Euria are cleaner: the conversation itself is not processed by a US firm.
Ask instead whether any US company is in the picture at all, payments and support included, and only DentroChat is left. Its subprocessor list is EU and Switzerland only. Payments go through Mollie in the Netherlands, and you can pay by SEPA direct debit via iDEAL, Trustly or Pay by Bank, which never touches a card network.
Lumo’s own privacy policy names Zendesk, Stripe, PayPal, Chargebee and Atlassian, and states their processing location as the United States. The chat stays in Europe, but the payment data goes to the US. Euria is the narrowest miss of the three alternatives: Infomaniak’s confidentiality policy names Checkout, which is British, and PayPal, which is US-American, but it also takes Twint, PostFinance and a plain bank transfer. These last ones use no payment provider at all.
One caveat applies to everyone equally. Card payments can leave Europe whoever the acquirer is, because Visa’s EEA notice says personal information may be transferred to or processed in the United States. The way around it is a non-card route. DentroChat has SEPA. Euria has Swiss bank rails. Vibe and Lumo bill through Stripe, so with those two no payment method avoids a US company.
GDPR compliance is not the differentiator between these EU AI Chats. All four meet it, including the ones that send payment details to American companies. GDPR does not say your data has to stay in Europe. Instead, it says there has to be a lawful basis for moving it, and transfers to the US currently have such lawful basis thanks to the EU-US Data Privacy Framework. But beware: That framework has already been struck down twice under earlier names (Safe Harbour, then Privacy Shield), and it is under review again. “GDPR compliant” and “no US company can be ordered to hand this over or stop the service” are completely different things.
A smaller thing: DentroChat is the only one that will delete old chats automatically on a schedule you set. Lumo’s free tier wiping chats after a few days is not the same feature: that is a cap on the free plan which you can’t disable.
What these EU AI Chats cost
Price says almost nothing about what you get. The most famous, Mistral’s Vibe, is not the one that won the test, but the cheapest actually does have the fewest features and weakest answer.
| Platform | Free tier | Monthly | Yearly |
|---|---|---|---|
| Vibe | Yes, capped | €14.99 | €143.90 |
| DentroChat | 15 messages | €12 | €97 |
| Lumo | Yes, history deleted after a few days | €12.99 | ~€120 |
| Euria | Yes, generous | €1.90 | €19 |
Euria’s €19 a year comes as part of Infomaniak’s kSuite+ bundle and is roughly a tenth of Vibe Pro. The free tier is generous enough that a lot of people will never need to pay. Lumo’s free tier looks similar on paper until you notice that chats are deleted after a few days, which makes it closer to a trial than a plan. Vibe still has the most usable free tier of the four if you only chat occasionally.
DentroChat instead of Vibe
What you are switching to is a simpler EU AI Chat with better answers. Instead of Vibe’s Work, Code and Chat modes you pick Fast, Thinking or Creative, and you can change that in the middle of a conversation. You still get code execution and real files (charts, spreadsheets, documents, slides). The interface is in 17 European languages. You can turn on auto-delete for old chats, export everything from the app, and pay by SEPA. The subprocessor list has no US companies on it.
What you give up is most of Vibe’s workspace. There are no connectors to Gmail or Atlassian, no background agents, no projects or folders, no read-aloud, and no native mobile app. You also give up the feeling that one European lab is doing everything. DentroChat does not train its own frontier models. It routes to several European inference providers.
The reason to consider the switch is usually the combination of the test and the stack: it went to the official source, and no US company sits in the chain. If you need the workspace, that might not be enough.
Lumo instead of Vibe
Lumo is Proton’s assistant, which is why most people try it, and also why they misunderstand it. Proton Mail is end-to-end encrypted, so it is natural to assume Lumo is too. It is not, and it cannot be. Your saved chat history is protected with zero-access encryption, which means Proton really cannot read old conversations back. However, the message you just sent has to be decrypted on Proton’s GPU servers in order to be processed by the AI, because no AI model can read ciphertext (for now). Proton says this in plain language. Even with that caveat, Lumo still has the best encryption setup of these four. Nobody else locks the provider out of stored history.
What you get is a very clean interface, an open-source app, image generation in its own tab, projects, ghost mode and a Proton Drive connection. In the test you also get the most careful answers of the four, if you are willing to wait about fifteen minutes for them. What you give up, compared with Vibe, is file generation, chat sharing, voice input, rendered maths.
Choose it if you already pay for Proton and would rather have an honest slow answer than a polished wrong one. Skip it if you need a spreadsheet at the end of the chat, or if you were expecting the same end-to-end guarantee you get from Proton Mail.
Euria instead of Vibe
Euria comes from Infomaniak, the Swiss hosting company that has been running its own datacentres for about thirty years and also sells the kSuite productivity package. Most EU AI Chats rent their servers from someone else. Infomaniak owns the buildings, the machines and the cooling, and it runs open-source models on them. That is the cleanest single-country sovereignty story in this list, and at €19 a year it is roughly a tenth of what Vibe costs. The free tier is generous enough that many people will never see a bill.
What you get is a snappy, professional interface, projects, share links, voice input and a kDrive connection. What you give up is almost everything else Vibe is good at: no image generation, no memory, no file creation, no code execution, no rendered maths, and no export button in the app. In the test the interface stayed tidy but the answer did not. The model’s private reasoning leaked into the reply, so you watched it correct itself on the way to a Sweden figure that was 64% too low…
Choose it if price and Swiss hosting are what you are looking for, but double check any number it gives you. It is excellent value for conversation and drafting, but not the tool to do research with.
What you lose if you leave Vibe
Vibe is the only one of these four that reads answers back to you with voice. It is the only one with connectors that reach outside its own house, the Gmail / Atlassian / Notion kind rather than “our own Drive”. It is the only one with background agents. It ships a native app on iOS and Android. Its free tier is a real free tier, not fifteen messages or a history that gets deleted after a few days. And Mistral is still the only European lab training frontier models from scratch.
If those are the reasons you picked Le Chat in the first place, your move is to stay on Vibe.
How to decide
If you need Gmail, Atlassian, agents or read-aloud, stay on Vibe.
If you want no US company anywhere in the chain, including checkout, you want accurate answers, a chart and a spreadsheet at the end of the chat, DentroChat is the one that actually does all.
If you already live in Proton, care more about not being misled than about speed, and can wait a bit, Lumo is the careful choice. Just do not expect files, and do not expect Proton Mail-style encryption on the live prompt.
If you want the cheapest Swiss EU AI Chat and you are mostly writing, not researching, Euria is a good option.
Is Vibe the same as Le Chat?
Yes. Mistral renamed Le Chat to Vibe on 28 May 2026. Your account, plan and old conversations moved with the name. Opening chat.mistral.ai still lands you in the same product, now with Work, Code and Chat modes instead of a single chat window.
Is Mistral Vibe actually a European EU AI Chat?
The company is French, and the models are trained in Europe. That part is not marketing. But be aware that the consumer app is a different story. Inference runs on Google Cloud, the website sits on US infrastructure vendors, and billing goes through Stripe. “European” describes the lab better than it describes the chat stack. The longer version, with the subprocessor lists side by side, is in DentroChat vs Mistral: which European AI chat is actually European.
What is the best Le Chat alternative if I care about privacy?
It depends which part of privacy you mean. If you mean “no US company can be compelled to hand this over”, DentroChat is the only one of the three with no US subprocessors at all. If you mean “the provider cannot read my old chats”, Lumo has the strongest encryption on stored history, even though the live prompt is decrypted for inference and billing still goes to the US. If you mean “I want the machines in Switzerland and I am willing to pay by bank transfer”, Euria is the cleanest single-country setup.
Does any EU AI Chat match Vibe’s connectors?
No. Lumo has Proton Drive, Euria has kDrive, and DentroChat has neither. If connectors are the reason you use Vibe, switching will feel like a downgrade on that axis no matter which alternative you pick.
Is DentroChat cheaper than Mistral Pro?
On the paid plan, yes: €12 a month, or €97 a year, against Vibe Pro at €14.99 a month or €143.90 a year. Vibe’s free tier is more generous if you only need occasional use. Euria undercuts both if price is the only thing you are comparing, at €1.90 a month or €19 a year as part of kSuite+.
