The verdict

Some questions are too messy for a Google search, like how to word a hard email or what a handwritten recipe says. ChatGPT takes them by text, live voice or a photo, makes images from a description and syncs your chats across iPhone, iPad and Mac. Plus costs $19.99 a month in the App Store, the same as Gemini Pro, and OpenAI says the cheaper $8 Go plan may include ads.
