Best Euria alternatives in 2026: three EU AI Chat platforms with more than Swiss hosting

Euria is the cheapest serious EU AI chat in this comparison. It is also one of the cleanest on hosting, because Infomaniak runs it on its own Swiss infrastructure. But cheap and Swiss does not automatically mean useful for every job.

In our August 2026 test, Euria refused to invent a fake EU directive, which was good. However, it also read Sweden’s industrial electricity price as a household price, skipped Poland, produced no files, and ended with a headline number of 295.4% when the real answer was 42.8%.

So if you like the idea of Euria but keep running into the ceiling, these are the three Euria alternatives worth trying:

DentroChat
Vibe, formerly Le Chat
Lumo

TLDR: Stay on Euria if price and Swiss hosting are the main points, and if you mostly write simple drafts. Switch to DentroChat if you want best in class research, work with files and no US company anywhere in the chain. Pick Vibe if you need connectors, agents, read aloud or a more complete workspace. Pick Lumo if Proton level trust and careful answers matter.

What Euria gets right

Most Euria alternative lists should start here, because Euria is not a joke product. It is small, fast and clean, and the price is almost unfair.

Euria comes from Infomaniak, the Swiss hosting company behind kSuite and kDrive. Infomaniak has been running its own datacentres for a loooong time. Most European AI chat apps rent servers from someone else. Infomaniak owns the data centers and the servers, and runs open source AI models on them. For someone who wants a single country Swiss setup, that is a strong argument.

This EU AI Chat is also cheap. The free tier is generous enough for casual use, and the paid version sits inside kSuite+ at about €1.90 a month or €19 a year. That is roughly a tenth of Mistral Vibe Pro, and much cheaper than DentroChat or Lumo.

The interface is snappy too. You get projects, share links, voice input, ephemeral chats, edit and branch, file upload, image understanding and a kDrive connection. For drafting, rewriting and everyday questions, that is more than enough for an AI Chat Europe.

And surprisingly, Euria was very honest about what it could not do in our test. It refused the fake EU directive and said it would not cite article numbers for a text it could not verify. When it could not find a Polish electricity price, it wrote: “I cannot fulfill the request for Poland without hallucinating.” That is exactly the kind of sentence you want from an assistant under pressure.

Why people look for an Euria alternative

People usually look for an Euria alternative for one of four reasons:

It has very few features. Euria can upload files, but it cannot create a spreadsheet, a chart file, a document or a presentation. It cannot run code. It cannot generate images. It has no memory across chats, no read aloud and no in app export.
The answer quality is uneven. Euria can be careful in one paragraph and careless in the next. In the same answer where it refused to hallucinate Poland, it accepted Sweden at €0.0970 per kWh without sanity checking it against its own quoted EU average of €0.2896.
The interface is clean but a little cold. This is subjective, obviously. Still, compared with Lumo, Vibe or DentroChat, Euria feels more like an sterile enterprise chat than a product with a personality.
Swiss hosting does not mean no US company anywhere. The chat itself is clean. However, Infomaniak’s confidentiality policy names Checkout and PayPal for payments. Checkout is British, PayPal is US American.

None of this makes Euria bad. It makes Euria a cheap Swiss assistant that is great for writing simple drafts or brainstorming.

How we tested each EU AI Chat

We gave each app the same prompt on its highest reasoning setting in August 2026. This was not a scientific benchmark. It was a hands on test to catch classic AI chat issues: stale sources, wrong arithmetic, hallucinated law and missing files.

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 table

The directive in the prompt does not exist, it was a trap to see if one of the EU AI Chat hallucinates ;-) There is a real Council Implementing Regulation (EU) 2026/1174, but it is about restrictive measures against Hamas and Palestinian Islamic Jihad, not residential energy prices. So the right answer was to refuse the directive instead of inventing it.

The real electricity prices, checked against Eurostat dataset nrg_pc_204 for the second half of 2025, band DC, all taxes included, are:

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.

We used the strongest version of each chat for the prompt, e.g. “Thinking”, “Max”, “Expert” etc.

Results

Result	Euria	DentroChat	Vibe	Lumo
Headline figure, true 42.8%	295.4%	42.8%	76.2%	51.2%
Refused the fake EU directive	Yes	Yes	Yes	Yes, and found the real regulation
Bar chart	No	Yes, in the chat	Yes, download to view	Yes, in the chat
Spreadsheet file	No	Yes	Yes	No, CSV text to copy
Time to answer	~1 minute	~1 minute	~1 minute	~15 minutes

Euria was the most explicit about not hallucinating, but then still produced the worst number. It refused the fake directive, declined article numbers and said clearly that it couldn’t find Poland. On Germany, it handled conflicting figures well and picked a value close to the true one. But then it reported Sweden at €0.0970 per kWh, which is Sweden’s industrial price, not the household price. Therefore, with no Poland and a broken Sweden, it reduced the calculation to Germany versus Sweden and got 295.4%. The answer also leaked raw reasoning into the user facing text, so you had to read the model correcting itself on the way to a wrong conclusion, unclean.

DentroChat was the only one that got the official numbers exactly right. It queried the Eurostat API directly, used the right dataset, the right consumption band and the same period for every country. It refused the fake directive, delivered a chart visible in the chat and attached a spreadsheet. However, it did not find the real Regulation 2026/1174, and it muddled two article numbers when pointing at the real Electricity Directive 2019/944. That is a citation slip, not invented law, but it is still a slip.

Vibe had the most polished product around the answer. It gave a well structured reply, refused the fake directive, produced both a chart and a spreadsheet, and got the 24 hour switching rule right. However, the electricity data was stale. Sweden and Poland came from December 2024 and were described as the latest Eurostat figures, even though Eurostat had already published the second half of 2025. Germany came from a different source and a different period, which pushed the headline to 76.2%. Mixing up clean timeframes and calling them “the latest” is unfortunate.

Lumo won the trick question. It found the real Regulation 2026/1174, noticed that it was a regulation rather than a directive, and said it had nothing to do with energy prices! Nobody else did that. It also read the Eurostat page carefully enough to recognise the exact Sweden figure Euria misread as industrial, not household. But Lumo took about fifteen minutes, mixed values, and could not attach a spreadsheet.

So: DentroChat got the official numbers and the files. Lumo got the hardest legal nuance but made us wait. Vibe looked the most complete but used stale data. Euria refused to lie about Poland, but then got Sweden badly wrong.

Euria’s biggest gap is output

Euria’s sovereignty story is strong. The reason to switch is usually not that the chat is secretly running on some US cloud. The reason to switch is that the product stops short when you ask it to do proper work.

Everyone in this comparison can search the web, upload files and understand images. Apart from that, Euria’s feature set is rather weak compared to the other EU AI Chat apps. For this comparison, we compared the browser web apps on desktop:

Feature	Euria	DentroChat	Vibe	Lumo
Create downloadable files	No	Yes	Yes	No
Run code	No	Yes	Yes	No
Image generation	No	Yes	Yes	Yes
Memory across chats	No	Yes	Yes	Yes
Read answers aloud	No	No	Yes	No
Render maths properly	No	Yes	Yes	No
Export data in the app	No	Yes	Yes	No
Connectors	kDrive	None	Gmail, Atlassian, Notion and more	Proton Drive

This is why Euria feels good until the moment you need an artifact. If you ask it to draft an email, fine. If you ask it to build a chart and give you a file, it has to explain why it cannot.

Vibe and DentroChat are the practical Euria alternatives if you want to work with files. Lumo shares Euria’s file limitation. However, Lumo is a better alternative if you want a more careful text answer.

Who can actually read your chat

All four EU AI Chat platforms keep the chat servers in Europe or Switzerland. So “European hosting” alone does not separate them much.

The better question is who touches the data.

	Euria	DentroChat	Vibe	Lumo
Chat servers in	Switzerland	EU + Switzerland	EU	EU + Switzerland
Payment provider based in	UK or US	EU	US	US
No US subprocessors in the chat	Yes	Yes	No	Yes
No US subprocessors anywhere	No	Yes	No	No
Ghost or incognito mode	Yes	Yes	Yes	Yes
Auto delete old chats	No	Yes	No	No
Interface languages	7	17	10	35

Euria is very good on the chat itself. Infomaniak runs the infrastructure in Switzerland. That is cleaner than Vibe, where inference runs on Google Cloud. A US owned company running servers in Europe is still a US company, and it still falls under the US CLOUD Act, so Vibe in that sense is much worse than Euria.

However, Euria is not completely free of US companies once you include payments. Infomaniak names PayPal, although you can avoid it through Swiss bank rails. Lumo has the same split: the chat is self hosted, but Proton’s Lumo privacy policy names Stripe, PayPal, Chargebee, Zendesk and Atlassian, with processing location in the United States. Vibe uses Stripe and Google Cloud, so it is the least sovereign of these four.

DentroChat is the strictest EU AI Chat option, and the only 100% European one. Its subprocessor list is EU and Switzerland only, and payments go through Mollie in the Netherlands. You can pay through SEPA direct debit routes such as iDEAL, Trustly or Pay by Bank, so you can avoid card networks too.

One caveat applies to everyone: card payments can leave Europe because Visa’s EEA notice says personal information may be transferred to or processed in the United States. Therefore, the real question is whether a non card route exists. Euria has Swiss routes. DentroChat has SEPA. Vibe and Lumo still go through US payment companies.

What Euria and the alternatives cost

Price is where Euria wins clearly.

Platform	Free tier	Monthly	Yearly
Euria	Yes, generous	€1.90	€19
DentroChat	15 messages	€12	€97
Vibe	Yes, capped	€14.99	€143.90
Lumo	Yes, history deleted after a few days	€12.99	~€120

If the question is “what is the cheapest EU AI chat that still feels professional”, Euria is the answer. There is no clever argument against that. It is much cheaper than the others, and the free tier is good.

But the price also explains the trade. You pay less, and you get less: no files, no images, no memory, no code execution, no export and weaker research output. For many people that is a perfectly reasonable deal. However, it is not the same category of AI assistant as Vibe or DentroChat.

Ranked for someone leaving Euria

DentroChat is the best Euria alternative if you want the same European sovereignty idea, but with real output. It got the exact Eurostat answer, produced the chart and spreadsheet, supports images, memory, code execution, export and auto delete, and has no US subprocessors anywhere.
Vibe is the best Euria alternative if you want the richest product. It has projects, agents, read aloud, memory, image generation, image editing, native apps and connectors to tools like Gmail, Atlassian and Notion. However, you take Google Cloud and Stripe with you.
Lumo is the best Euria alternative if you want careful answers and Proton trust. It was the only app to solve the fake directive trap fully and has zero access encryption for saved history. However, it is slow on deep research (15 minute wait!) and cannot create real files.

DentroChat after Euria

What you are switching to is a more capable EU AI chat that still keeps the stack European. In DentroChat you pick Fast, Thinking or Creative, and you can change that mid conversation. You get code execution, charts, spreadsheets, documents, slides, image generation, image editing, memory, voice input, share links, full data export, rendered maths and auto delete for old chats.

The big practical difference is that DentroChat finishes the work. In the test, Euria offered workarounds because it could not create files. DentroChat attached the spreadsheet and showed the chart in the chat. And it was the only one with the correct answer.

You also get a stricter sovereignty setup. Euria is clean for chat, but not clean across the whole chain. DentroChat’s published subprocessor list has no US companies at all, and checkout runs through Mollie rather than PayPal, Stripe or Checkout.

What you give up is Euria’s price and Swiss single country story. DentroChat costs €97 a year rather than €19, and it has no projects, folders or kDrive style storage connection. It is better if you want a working assistant. It is not cheaper, and it is not Swiss only.

Vibe after Euria

Vibe is the opposite upgrade. It is what you pick if Euria feels too small.

Mistral’s app has the most complete feature set here: connectors, agents, projects, library, native apps, read aloud, memory, image generation, image editing, voice input, full export and a proper free tier. If your complaint about Euria is that it does not reach the rest of your work, Vibe is the strongest answer.

However, the sovereignty trade hurts. Vibe is European at the company level, but the consumer app runs inference on Google Cloud and bills through Stripe. It matters a lot if the whole reason you tried Euria was avoiding US companies.

In the test, Vibe also made a classic research mistake. The answer looked good, but it mixed dates and sources, then called stale Eurostat data current. So Vibe is the best workspace upgrade, not necessarily the best accuracy upgrade.

Lumo after Euria

Lumo is the alternative for people who like Euria’s privacy direction but want a more polished and careful assistant.

Proton’s product has the strongest stored message history protection in our EU AI Chat comparison. Saved chats are zero access encrypted, so Proton cannot read old conversations back. The live prompt still has to be decrypted on Proton’s GPU servers for inference, because no AI model can answer encrypted text. But compared with Euria, DentroChat and Vibe, Lumo has the strongest encryption setup for saved history.

It was also the most careful on the fake EU directive. It found the real Regulation 2026/1174 and explained why it was unrelated. On the exact same Eurostat page, it correctly treated Sweden’s €0.0970 number as industrial, while Euria put it into the household column. That contrast is not flattering to Euria.

However, Lumo does not fix Euria’s output problem. It also cannot create a spreadsheet, run code or render maths properly. It has no voice input and no chat sharing. And in our test it took about fifteen minutes. Choose Lumo if you want carefulness and Proton trust.

What you give up if you leave Euria

You give up the cheapest serious paid plan in this list. The yearly plan costs almost as little as the monthly plan of the EU AI Chat options.

You also give up Swiss infra simplicity. Infomaniak owns and runs the infrastructure, and for some people that is the appeal. If you pay by Twint, PostFinance or bank transfer, Euria can be a very clean Swiss setup.

And you give up kDrive. DentroChat has no storage connector, Vibe has many connectors, but not kDrive as the native home. Lumo has Proton Drive instead.

So if you mostly use Euria for drafting, translation, summaries and short questions, you may not need an alternative at all. The problems show up when you ask it to research, calculate, create files or remember context across chats.

How to decide which EU AI Chat to choose

If you want the cheapest Swiss AI chat and mostly write text, stay on Euria.

If you want the best research, code execution, a real spreadsheet, images, memory, data export, auto delete and no US company anywhere in the chain, choose DentroChat.

If you want connectors, agents, read aloud, projects and the most complete feature set, choose Vibe.

If you trust Proton, care about stored history encryption, choose Lumo.

Is Euria really Swiss?

Yes. Euria is built by Infomaniak and runs on Infomaniak’s Swiss infrastructure. That is its strongest argument. The caveat is payments: Infomaniak names Checkout and PayPal, although Twint, PostFinance and bank transfer give Swiss routes that avoid PayPal.

Is Euria better than Lumo?

It depends. Euria is much cheaper and has voice input, share links and kDrive. Lumo is more polished, has stronger stored history encryption, image generation and is more deliberate in its answers in our test. Neither can create real files.

What is the best Euria alternative for privacy?

If you mean Swiss hosting, Euria itself is still excellent. If you mean stored history that the provider cannot read, Lumo is stronger. If you mean no US company anywhere in the stack, including payments, DentroChat is the cleanest option.

Can Euria create spreadsheets or charts?

No. In our test Euria said upfront that it could not generate downloadable charts or spreadsheets. DentroChat and Vibe can create real files. Lumo can draw a chart in the chat, but it gives CSV text to copy rather than a spreadsheet file.

Why was Euria’s electricity answer so wrong?

It appears to have read the wrong column of the Eurostat table. The €0.0970 per kWh figure it used for Sweden is the industrial electricity price, not the household price. The correct household figure for Sweden was €0.2711 per kWh, which is why Euria’s final 295.4% result was so far away from the real 42.8%.
