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.

What to Check Before Switching from OpenAI
Where your data will be stored
5 of the 14 alternatives here say they keep data in the EU only. Cortecs AI, Curiosity, Dust, H Company, Mistral AI and Stability AI offer an EU region alongside others, so choose it explicitly when you set up the account. Alan AI, Berget AI and Soev AI do not state where data is stored. Ask before you move anything sensitive.
How you can try it
Curiosity, DentroChat, Mistral AI and Stability AI have a free plan, so you can run a real test before cancelling OpenAI. Alan AI, Aleph Alpha, H Company, LightOn, Outmind, Soev AI and Zylon 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.
What you need to bring from OpenAI
List the data, templates and integrations you rely on in OpenAI, then confirm each one can be exported and that the alternative can import it or offers an API to rebuild it.
