RewriteBar

The application lives in the macOS menu bar and provides instant AI‑powered text processing for any active application. Users can invoke a window with a keyboard shortcut, select a snippet of text, and choose from actions such as grammar and spelling correction, tone adjustment, or translation. The tool supports over 500 languages and can operate with local AI models, keeping data on the device.

It also allows creation of custom workflows by chaining multiple actions—e.g., expanding a paragraph, adding emojis, then translating—so users can tailor the assistant to specific writing tasks. A side‑by‑side comparison view shows original versus rewritten content, and integration with PopClip offers additional shortcut access.

The software targets writers, developers, and anyone who regularly composes text across different macOS applications, offering a unified interface for quick fixes, multilingual translation, and personalized AI actions without leaving the current workflow.
