SimpleLMDownload SimpleLM.
SimpleLM is an offline AI assistant for iPhone and iPad, and the beta is open. The language model downloads once and then runs on the device, so there is no account to create and no connection needed to use it.
Free to install. Needs Apple’s TestFlight app and iOS 17 or later. If a build will not install, write to support@simplelm.co.
