RewriteBar

RewriteBar is a powerful and lightweight AI writing assistant designed exclusively for macOS. Integrated directly into your menu bar, it provides on-demand writing support within any application you use, from Slack and Notion to Xcode and your web browser. This tool is built to enhance productivity by allowing users to refine their writing without breaking their workflow. Whether you need to fix grammar, adjust the tone of an email, translate a sentence, or even improve a ChatGPT prompt, RewriteBar makes it possible with a simple keyboard shortcut.

The core philosophy of RewriteBar is to provide a seamless, distraction-free experience. Instead of copying and pasting text into a separate window or website, you simply select the text you want to modify, trigger RewriteBar, and choose from a list of predefined or custom actions. The AI processes your request and instantly replaces the selected text with the improved version. This efficiency makes it an indispensable tool for professionals, students, developers, and non-native speakers who want to communicate more clearly and effectively.

How to use RewriteBar

Getting started with RewriteBar is straightforward and designed for immediate productivity:

1. Download and Install: Download the app from the official website. It's a lightweight application (around 20 MB). Drag it to your Applications folder to install.
2. Grant Permissions: On the first launch, RewriteBar will ask for macOS Accessibility permissions. This is necessary for the app to read the text you've selected and paste the rewritten version back into your active application. Your data remains private and is not stored.
3. Activate License: You can start with a free trial which offers up to 100 free actions. After that, you can purchase a subscription or a one-time license.
4. Select and Rewrite: Highlight any text in any application (e.g., an email, a chat message, a line of code).
5. Use the Shortcut: Press your custom keyboard shortcut to bring up the RewriteBar command menu.
6. Choose an Action: Select an action from the menu, such as 'Fix Grammar & Spelling', 'Simplify Language', 'Translate', or any custom action you've created. The selected text will be instantly replaced with the AI-generated output.
