Short Circuit is a ChatGPT app available for iPhone, iPad, and Mac, offering an AI assistant called Shorty.

The app provides a premium ChatGPT experience and works seamlessly with Siri, Shortcuts, and other system features.

Short Circuit allows users to engage in conversations with personas representing various personalities, including a French tour guide, a math tutor, or a SwiftUI expert.

The app emphasizes privacy by promising not to use users' questions and answers to train OpenAI models, distinguishing itself from other ChatGPT apps that may employ user data for training.

Additionally, Short Circuit offers a subscription-based model for accessing its services on Apple devices.

However, users also have the option to make a one-time payment for a lifetime unlock, which includes the ability to use the app with their own OpenAI token.

This lifetime unlock provides an affordable option for infrequent use.

Moreover, the app offers a free trial to help users familiarize themselves with its features.

For support and inquiries, Short Circuit provides the option to reach out through Mastodon or email.

Overall, Short Circuit aims to deliver a convenient and customizable ChatGPT experience while prioritizing user privacy and offering flexible payment options.
