JackAI brings local model chat, photo and audio AI to iPhone and iPad

JackAI is an on-device AI assistant for iPhone and iPad that runs supported local models for chat, photo Q&A, audio transcription and note summarization, keeping prompts and files in local app storage. It requires iOS or iPadOS 26 or later, and downloadable models need an internet connection and several gigabytes of storage. On compatible devices with Apple Intelligence enabled, it can also use Apple's on-device Foundation Model.
