Palettebrain
PaletteBrain is a macOS-first ChatGPT client and system-wide AI command palette that lets you run AI prompts on selected text inside any app or website. It works by letting users bind keyboard shortcuts to custom AI commands (templates) and run those commands against highlighted text, then paste replies back into the originating app. The product is aimed at founders, creators, marketers, engineers, teachers and teams who want to integrate ChatGPT-style workflows directly into their macOS environment without switching windows or copying/pasting.
PaletteBrain is sold with a one-time lifetime license (or limited-time early-supporter pricing) and requires users to provide their own OpenAI or Microsoft Azure OpenAI API key so usage is billed directly to those services. The team emphasizes privacy (traffic is between the user’s computer and the chosen API provider), fast model access, and extensive customization of commands, models and keyboard shortcuts. A roadmap includes Agent.so integrations, multi-model support, file/chat multimodal features, syncing and improved organizational tools.
