MacGPT is an innovative macOS application that seamlessly integrates ChatGPT into your Mac's menubar, offering easy access to AI-driven support. The application's Global feature enables users to summon a text input field in the center of their screen, facilitating ChatGPT interactions from any location on the Mac. Additionally, the Inline feature allows users to incorporate ChatGPT directly into text fields by entering a specific trigger phrase followed by their query, making text completion more efficient. Quick access to ChatGPT is made possible through the Menubar feature, which connects users to the service via the website or natively through the API. Moreover, MacGPT includes a Conversation Mode, which allows for hands-free voice interactions with ChatGPT, eliminating the need for keyboard input. User privacy is a top priority, as the application does not track or store any personal data, ensuring all connections are made directly to OpenAI APIs. Supporting macOS Monterey and Ventura, MacGPT is also compatible with ChatGPT Plus accounts, giving users the option to log in and utilize GPT Plus features. With its diverse functionalities, MacGPT enhances productivity and makes AI assistance readily available whenever needed.
