Offline AI Chat & Assistant

Acerca de esta app

Offline AI Chat & Assistant is an iOS application designed to run large language models locally on the device, eliminating the need for an internet connection. By processing prompts and generating responses entirely on the iPhone, it ensures that user data never leaves the device, making it suitable for confidential work, travel without roaming data, or general privacy-conscious usage. The app supports streaming responses as they are generated and includes a lighter model option for devices with limited resources.

The core functionality allows users to chat, write, plan, code, and brainstorm without relying on cloud servers. There is no requirement for an account or sign-in, reducing friction and waiting times associated with server-side processing. For more demanding tasks, the “Offline AI Pro” upgrade provides deeper reasoning capabilities via Thinking Mode, context windows up to 32K tokens, reusable system prompts, and granular control over generation parameters such as temperature, Top-K, and Top-P. Users can also select between CPU or GPU runtime options when available to optimize performance.

An initial download of the AI model is required before offline generation becomes available, and performance depends on the specific device hardware and selected runtime settings. The app is free to use, with optional in-app purchases for advanced features through a weekly subscription model.
