Ever wished you could fix a clunky sentence in Slack, polish a sermon outline in your notes app, or translate a church announcement — all without leaving the app you're already in? RewriteBar is a lightweight macOS menu bar tool that does exactly that. Select any text in any application, trigger a keyboard shortcut, and choose from AI-powered actions like grammar correction, tone adjustment, translation into 500+ languages, text expansion, and summarization.^1
Built by indie developer Mathias Michel and founded in 2024, RewriteBar has grown into a comprehensive AI writing toolkit supporting 37 cloud and local AI providers — including OpenAI, Anthropic, Google, DeepSeek, and local models through Ollama, LM Studio, and Apple Intelligence for complete privacy.^2 You can create custom actions tailored to your workflow, like reformatting sermon notes, generating discussion questions, or translating content for a multilingual congregation.^1
Pastors and church communicators will appreciate how RewriteBar fits into their existing workflow. Whether you're drafting emails to volunteers, polishing a blog post, or adjusting the tone of a social media update, it works inside the apps you already use — Google Docs, Microsoft Word, Slack, Notion, and more.^1 Version 2 added follow-up actions, session history, side-by-side comparison view, Apple Shortcuts integration, and personal context that tailors results to your voice and role.^3
