RewriteBar

RewriteBar is a robust macOS menubar tool that enhances your writing by integrating AI-driven text improvements into any Mac application. With a compact 20MB size and smooth integration, RewriteBar removes the need to switch between applications when refining your writing.

Simply select text in any macOS app—whether you're writing emails in Mail, composing messages in Slack, coding in your preferred editor, or drafting documents—and choose from various AI-powered functions to quickly transform your content. The app works smoothly with existing tools like Grammarly, offering an extra level of writing support without causing conflicts.

Core features include correcting grammar errors that even sophisticated spell-checkers miss, rewriting text in different styles and tones, translating content without leaving your current application, simplifying complex sentences for better understanding, and expanding or condensing paragraphs. You can even design personalized AI actions tailored to your specific needs.

Leveraging OpenAI and other prominent AI services, RewriteBar delivers professional-level writing assistance that adapts to your needs. Whether you're a developer creating technical documents, a professional crafting business communications, or anyone who values clear, effective writing, RewriteBar optimizes your workflow and improves your content quality with just a few clicks from your menubar.
