The best European AI chatbot overall is Mistral Vibe (France), formerly Le Chat, built on Mistral's own models with a free plan, web search, image generation and voice. For the most private chats, choose Lumo by Proton (Switzerland); for a free assistant processed only in Switzerland, Euria by Infomaniak.
This is the overview of every AI chatbot from Europe that I would consider, with one line on who each one is for. If you are leaving ChatGPT, the deeper comparison is in Best European alternatives to ChatGPT. All prices and facts were checked on the providers' own pages on 25 October 2026.

How I chose the best European AI chatbots
I compared ten AI chat services from the EU, Switzerland and the rest of Europe and kept seven. Each one was checked on the same five points: jurisdiction and ownership, which models it runs on and where, features (free plan, apps, web search, images, voice), privacy (training on your chats, retention, encryption) and price together with user ratings. A European company is not always a European stack: two of the tools below run US models on US clouds, and I say so for each of them. Aleph Alpha, DeepL and HuggingChat are not listed – the first two have no consumer chat assistant, and HuggingChat comes from a US-incorporated company.

European AI chatbots: FAQ
Is there a European AI like ChatGPT?
Yes. Mistral Vibe (formerly Le Chat) from France is the closest match, built on Mistral's own models. Lumo (Proton) and Euria (Infomaniak) are Swiss assistants that run open-source models on their own servers.
Which European AI chatbot is free?
Mistral Vibe, Lumo, Euria, GDPRchat and Ecosia AI all have free plans with usage limits. Euria is included in Infomaniak's free my kSuite account.
Which AI chatbot is best for privacy?
Lumo by Proton: your chat history is zero-access encrypted, there are no logs and chats are not used for training. Euria and GDPRchat also say they do not train on your chats.
My verdict
Pick Mistral Vibe if you want the most complete European chatbot, Lumo if you want nobody to read or train on your chats, and Euria if you want a free assistant processed only in Switzerland.
