PaletteBrain
PaletteBrain adds custom AI commands and ChatGPT integration to Mac workflows through a one-time-purchase app.
About PaletteBrain
PaletteBrain is a macOS app that puts ChatGPT-based AI commands behind a keyboard shortcut, so selected text in any app or website on the Mac can be rewritten, translated, summarized or otherwise transformed without switching windows and copying text. Users can build their own commands from prompts and run them anywhere, including Notion, Google Docs, Slack, Discord and Gmail.
It works with your own OpenAI API key, so usage is billed by OpenAI rather than through a ChatGPT Plus subscription, and keys can be swapped for Microsoft Azure OpenAI. The software is macOS-only, and the homepage advertises a one-time lifetime license rather than a recurring fee.
