Macaify

Macaify is a free, open-source macOS app that brings AI directly into any app on your Mac, so you don’t have to copy text, switch windows, or wait for a browser response.

How it works

Select text in any application, press your chosen keyboard shortcut, and Macaify shows the AI result right where you’re working—over the original text.

Common use cases

• Improve writing style and clarity
• Translate text
• Create an outline or structure for a document
• Rewrite and polish social media posts
• Other everyday text workflows across apps

Privacy and requirements

Macaify follows a local-first approach and doesn’t impose strict quotas. It runs on macOS 12+ and works with both native and web apps on your computer, staying lightweight and unobtrusive for daily work.
