## Overview
RewriteBar is a lightweight macOS menu bar tool that provides AI-powered writing assistance directly within any application. Users can select text and trigger the tool with a keyboard shortcut to access features like grammar correction, tone adjustment, text rewriting, and translation to over 500 languages. The tool works seamlessly across applications including email, documents, Slack, and code editors without disrupting workflow.

The application emphasizes privacy and flexibility by supporting multiple AI providers—including OpenAI, Anthropic, DeepSeek, and local models through Ollama—allowing users to bring their own API keys. A key distinction is its one-time purchase license model alongside a subscription option, letting users avoid recurring fees. The tool includes custom workflow creation, side-by-side comparison of changes, and PopClip integration, making it adaptable to individual writing processes.

One limitation is that RewriteBar is macOS-only with no Windows version available, which restricts its accessibility for users on other operating systems.
