Overview

What it is

Enhance your writing in any application using AI. Improve sentences effortlessly in Slack, emails, or a code editor. Works well with tools like Grammarly for better writing.

Intent

I need it when

Fix grammar and spelling errors quickly across any macOS application

RewriteBar captures selected text via keyboard shortcut and uses AI to correct grammar, spelling, and punctuation in context, then pastes the corrected version back. Works in any macOS app (Gmail, Slack, Word, Notion, etc.) without leaving the current application.

Maintain privacy while using AI writing assistance without storing personal data

RewriteBar supports local AI models (Ollama, LM Studio, Apple Intelligence) for completely offline processing, or direct API integration with providers where text never touches RewriteBar servers. Users retain full control over data and can choose between cloud or local processing.

Improve writing quality and clarity without switching between multiple tools

RewriteBar provides 40+ pre-built templates for common tasks (humanize AI text, simplify language, improve tone, extract action items, create summaries) accessible via keyboard shortcuts. All features work within the user's current application, eliminating context-switching and maintaining writing flow.

Create custom AI-powered writing workflows tailored to specific tasks

RewriteBar allows users to build custom actions by combining multiple AI operations (expand, translate, rewrite, add emojis) into single workflows. Users can create templates for emails, social media posts, user stories, or any repetitive writing task and trigger them via keyboard shortcuts.

Translate text to multiple languages while maintaining formatting and code integrity

RewriteBar supports translation to 500+ languages with options to preserve code elements and formatting. Users can translate words, sentences, or code snippets directly within their working application using a single keyboard shortcut.

Drop

Not a fit when

  • User requires Windows or Linux support; RewriteBar is macOS-only with no Windows version planned
  • User needs real-time collaborative editing across multiple users; RewriteBar is a single-user local application
  • User requires integration with non-macOS applications or web-based writing platforms beyond basic text input fields
  • User needs advanced plagiarism detection or citation management; RewriteBar focuses on grammar, tone, and translation
  • User operates in an environment where local AI models are unavailable and cannot use cloud API providers
