AI assistants
Dominant AI assistants from US tech giants harvest vast amounts of user data for model training, raising significant privacy concerns. They often prioritize capabilities over data protection. It is perfectly acceptable to use American AI tools for many tasks, as long as you are fully aware of the privacy and data sovereignty risks involved. For sensitive or sensible requests, however, European alternatives like Le Chat or Proton Lumo deliver strong, relevant results without tracking your identity or storing your conversations. While some American options may indeed excel in specific specialized tasks, European providers ultimately offer better protection for your digital footprint and actively support local innovation in ethical, transparent AI development.
