RewriteBar

RewriteBar is a macOS-based AI writing assistant designed for writers, researchers, and professionals who want to improve text across applications. It works inside any app where text can be selected, using AI-powered actions to fix grammar, adjust tone, or translate content. The tool aims to streamline writing tasks by providing quick fixes and configurable workflows, all accessible from a simple shortcut. The product emphasizes privacy through local model support and direct integration with AI providers.

RewriteBar captures the currently selected text via the macOS clipboard, sends it to a language model for rewriting, and pastes the corrected version back in place. Users trigger a main command menu, choose actions, and view results in a clean interface. The app supports offline and cloud options, depending on the chosen provider, and can test connections to local or cloud models before applying changes.

RewriteBar provides a comprehensive set of writing tools, including grammar correction, translation across 500+ languages, and the ability to create custom rewrite actions. It supports multiple AI providers, including local options, and emphasizes a distraction-free interface with quick keyboard shortcuts. Features include side-by-side comparison of original and rewritten text, and the ability to run multiple actions in a single flow for step-by-step transformations.

RewriteBar’s site outlines plans for licenses, platform focus on macOS, and integration options. It mentions a Free trial, a Standard one-time license, a Pro license with a RewriteBar Gateway, and add-ons like extra devices and gateway credits. It also notes local AI support via Ollama and cloud options with BYOK or cloud services. The product is positioned as a toolkit for macOS users needing multilingual support, privacy options, and direct AI integration.
