Who should get which
Get ChatGPT if
You want 1 AI assistant on your phone and Mac that you can type to, talk to or show a photo.
Get Gemini if
You already keep your life in Gmail, Google Drive and Calendar and want an assistant that can search them.
Skip ChatGPT if
You ask an AI something a few times a week, and the free plan answers that without a subscription.
Skip Gemini if
You don't use Gmail, Drive or Google Calendar, because then its biggest edge over ChatGPT or Claude is gone.
Our verdicts
ChatGPT
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.
Gemini
Google's Mac app isn't in the Mac App Store; it's a free download that pops up over any window with Option-Space and can read what's on your screen. Next to ChatGPT and Claude, the reason to pick Gemini is that it searches your own Gmail, Calendar, Drive and Photos. The Mac app needs an Apple silicon Mac on macOS 15 or later, and Gemini inside Gmail and Docs takes the $19.99 Pro plan.
