macOS AI writing assistant that works inside any app
RewriteBar captures the selected text system-wide and pastes the improved version back, so it functions in Chrome, Google Docs, Word, Slack, Notion, VS Code, email clients and more.
Use built-in commands such as fix grammar, simplify, humanize, summarise, title case, fix JSON, create ASCII art or translate, or author your own commands with variables and prompt libraries.
Combine several actions to transform text step by step — for example expand, add emojis, translate and rewrite a title in one flow.
Bring your own API key from major providers, use the RewriteBar Gateway, or keep everything on-device with Ollama, LM Studio, oMLX or Apple Intelligence.
Your tone dial for Slack messages
Rewrite any Slack message in professional, casual, friendly, concise, cheerful, or encouraging tone with a slash command.
Drop /reply in a channel and Vibe Shift reads recent conversation history to draft a context-aware reply automatically.
Set personal writing preferences that apply to every rewrite so the output consistently sounds like you.
Results appear in seconds inside Slack with no app switching or copy-pasting, on desktop and mobile across channels, DMs, and threads.
