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 stands out for its simplicity and flexibility. At just 25 MB, it runs quietly in the background and supports multiple AI providers — including OpenAI, Anthropic, DeepSeek, and even local models through Ollama and LM Studio for complete privacy.^2 You can also create custom actions tailored to your workflow, like reformatting sermon notes, generating bullet points from a topic, 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
