ZimaOS
Phone-simple, with AI photo search
ZimaOS is a NAS system from IceWhale, the company behind the ZimaBoard and ZimaCube and the earlier CasaOS. It is built with Buildroot, updates over the air and has a phone-like interface with an app store. Version 1.8 added ZimaOS Photos, which can search photos in plain language using AI that runs on the device. It runs on ZimaSpace hardware and on generic 64-bit PCs with UEFI.
