LLM Hub

LLM Hub is a private AI assistant that runs on your iPhone. Chat with local LLMs, generate images, video and music, translate, transcribe and build apps by describing them, with models that run on your device instead of in the cloud.

Pick the models you want, download them once and use them offline. Your prompts, chats and creations stay on your device during local inference. No account needed.
