Enclave vs cloud AI companion apps: The privacy difference self-hosting makes

The most fundamental difference between Enclave and mainstream cloud AI companion apps is data ownership. Cloud companion apps store your private conversations on their servers, and you can't verify for yourself how they're used; Enclave is open-source and self-hostable, with data kept only on your own drive — privacy guaranteed not by promises, but by your own machine.

How to choose

If privacy and data sovereignty are your top priorities, Enclave's self-hosting is hard for cloud companion apps to match; if you don't mind hosting your data on a platform and just want convenience, cloud apps are quicker to get started with. Enclave means you don't have to choose between 'easy to use' and 'my data stays mine.'
