PaletteBrain

PaletteBrain is a macOS application designed to bring ChatGPT capabilities across the user’s Mac. It integrates with the operating system to run AI commands on selected text in any app or website, accessed via a keyboard shortcut. The tool emphasizes a one-time purchase and local customization, avoiding ongoing subscription fees. It targets individuals who need AI-assisted productivity across various macOS workflows, including writing, coding, and data tasks.

PaletteBrain operates by enabling AI commands to be launched from a global shortcut.

The app is designed to be a prompt-driven interface that travels with the user’s Mac environment, embedding AI capabilities into the native apps and sites the user already uses.

PaletteBrain offers customizable AI commands that users can create to automate common actions such as grammar fixing, summarization, and code refactoring. It supports running AI on text selected in any app, pasting the response back via a shortcut, and binding commands to shortcuts for quick access. The product emphasizes privacy by keeping data between the computer and OpenAI or Azure, and maintains conversation history locally.
