Our verdict

Short Circuit wraps ChatGPT and GPT-4 in a native app for iPhone, iPad and Mac, adding Siri and Shortcuts support plus adjustable personas, creativity and model choice per conversation. Built-in fact-checking offers a second opinion when an answer seems doubtful, and the developer says it opts your data out of OpenAI's model training. It costs money either way: a subscription for most users, or a one-time lifetime purchase for anyone willing to supply their own OpenAI key.
