MacGPT is an app that lets you chat with ChatGPT, a powerful AI chatbot, on your Mac. It integrates ChatGPT into your menu bar, so you can access it from anywhere on your Mac. You can also use it in any text field with the inline feature, or use the global feature to chat with ChatGPT in a pop-up window. MacGPT works with your existing ChatGPT or OpenAI account, and supports both web and native modes. MacGPT is currently free, but will cost $5 when it launches on the App Store.
