RewriteBar

RewriteBar is a desktop AI assistant for macOS that fits into your daily writing flow and helps improve text in any app. Select a passage, open the panel with a keyboard shortcut, and choose an action.

Edit text across macOS apps

RewriteBar works on top of Apple apps and third-party editors—from Notes and Mail to browsers and messengers. It’s designed for quick, in-context edits without switching tools.

• Fix spelling and grammar
• Change tone and writing style
• Shorten or expand text
• Translate into other languages

Local models, workflows, and PopClip

RewriteBar supports local models, reducing reliance on the cloud and improving responsiveness. You can also create custom workflows for repeatable tasks and run them with a single click.

• Run actions from text selection with PopClip integration
• Use 500+ languages for multilingual writing, localization, and international content

Who it’s for

RewriteBar is useful for anyone who writes a lot on a Mac, including editors, developers, marketers, and students who want faster revisions and cleaner copy.
