Jack AI

Jack is an offline assistant for iPhone and iPad that keeps your chats, speech, and photos on your device. Key capabilities: • Chat with models installed locally • Translate live speech as someone talks • Transcribe live audio or imported recordings • Summarize notes and rewrite drafts • Pull text from photos and PDFs • Create checklists and QR codes. Jack works without an internet connection once your models and languages are downloaded. You can download the models you need while connected, import compatible models from Files, or use Apple's on-device model when it is available. Jack processes your prompts, audio, and photos on your device, so your content stays private. Action shortcuts such as Plan a meeting, Improve a draft, and Review a file help you start a specific task quickly. Perfect for travelers who need translation without roaming data, students and professionals who want to summarize notes and transcribe lectures or interviews, and anyone who handles sensitive documents and prefers not to upload them to the cloud.
