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.

Highlight text in Mail, Slack, Notes, browsers or a code editor, press ⌘⇧K, and Vidix sends the context to your chosen model and inserts the answer in place — no copy/paste or app switching.
Open the palette to search recipes, prompts and agents with arrow keys and Enter, so you can trigger an AI action without leaving the app you are working in.
A Markdown buffer sits between the model and your document so you can iterate with follow-ups like "make it shorter" or "make it legal" before confirming insertion with ⌘⏎.
Chain multiple AI steps into a saved workflow — for example security analysis, performance review, test coverage and documentation steps followed by a summary.
