European Alternatives to ChatGPT
OpenAI’s AI chat assistant, with free and paid plans for individuals, teams and enterprises. Below are 9 alternatives from companies headquartered in France, Estonia, Germany, Spain and the Netherlands. 4 of them keep data in the EU only, and 3 have a free plan.
Headquartered in Europe
Every company listed here has its headquarters in the EU, EEA, UK or Switzerland, not just a data centre there.
Data location you can check
The pricing table shows whether each one keeps data in the EU only, offers an EU region, or does not say.
Outside the US CLOUD Act
US providers can be ordered to hand over data held in their European data centres. A European company with no US parent or US operations is outside that reach.

Alan (by Comma Soft) is a German enterprise generative AI platform based in Bonn, providing secure AI chat and autonomous agents designed for data sovereignty. The platform enables organizations to deploy ChatGPT-like capabilities within their own infrastructure or on German cloud servers, ensuring that sensitive data never leaves the organization's control. Alan supports multiple LLM backends and provides tools for building custom AI agents that can access internal knowledge bases, execute workflows, and interact with enterprise systems. The platform is particularly popular with German enterprises and public sector organizations.
French enterprise AI workspace for internal assistants, knowledge retrieval, and multi-model workflows.
French enterprise generative AI platform focused on sovereign deployment, private assistants, and regulated-team rollouts.
Spanish private AI assistant platform for on-prem document Q&A, summarization, and workflow automation in sensitive environments.
Soev.ai is a Dutch sovereign AI platform focusing on maximum information security and autonomy. The platform is developed open-source, runs on EU infrastructure, and provides organizations with a secure environment for deploying and using AI models without data leaving European borders. Soev.ai targets organizations in government, healthcare, legal, and financial sectors where data sovereignty is non-negotiable. The platform offers chat interfaces, API access, and integration capabilities for building AI-powered workflows.
Outmind is a French enterprise search platform founded in Paris that uses generative AI to provide instant access to internal company knowledge. The platform connects to all enterprise tools and surfaces answers from across documents, emails, chat messages, and databases through a single search interface. Outmind uses RAG (Retrieval-Augmented Generation) to generate accurate answers sourced from the organization's own data, with citations linking back to original documents. The platform is designed for knowledge workers who waste hours searching for information across fragmented tools.
Curiosity is a German AI-powered knowledge management and search platform founded in 2020 in Berlin, providing a unified search experience across all of a user's apps, files, and data sources. The platform connects to 40+ applications (email, cloud storage, CRM, project tools) and uses AI to search across everything from a single interface. Curiosity goes beyond simple file search by understanding context, relationships, and content within documents, enabling users to find information by describing what they need in natural language. The platform runs locally on the user's device with optional cloud sync, ensuring privacy and fast performance.
What to Check Before Switching from ChatGPT
ChatGPT can export your chat history from its data controls settings. Download it before you cancel if you want to keep past conversations.
Custom GPTs and project instructions do not carry over to another assistant. Copy their instructions and any uploaded files so you can rebuild them.
Several alternatives here are enterprise platforms sold on request rather than apps you can sign up for yourself. If you want an individual subscription, look for a published price in the pricing table.
Where your data will be stored
4 of the 9 alternatives here say they keep data in the EU only. Mistral AI, Dust and Curiosity offer an EU region alongside others, so choose it explicitly when you set up the account. Alan AI and Soev AI do not state where data is stored. Ask before you move anything sensitive.
How you can try it
Mistral AI, DentroChat and Curiosity have a free plan, so you can run a real test before cancelling ChatGPT. Alan AI, LightOn, Zylon, Soev AI and Outmind sell on custom quotes only, which usually means a sales call before you can try it.
Open source
Mistral AI releases its software or models under an open licence, which makes it easier to self-host, inspect what runs, and move again later.
Security certifications
Certifications we have confirmed on the vendor’s own site: Outmind (ISO 27001). If your procurement requires one, check the others directly.
