Which operating systems does RewriteBar support?

RewriteBar is a macOS application, built with native macOS tools, and is not offered for Windows or Linux.

Do I need my own API key?

No. You can buy the Pro licence or the RewriteBar Gateway subscription to get cloud model access included, or use free local models. Alternatively you can bring your own key from providers such as OpenAI, Anthropic, Mistral or Google and pay them directly.

Is my text stored anywhere?

About RewriteBar

Works in any application

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.

Preset and custom AI actions

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.

Chain actions into workflows

Combine several actions to transform text step by step — for example expand, add emojis, translate and rewrite a title in one flow.

Cloud or fully local models

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.

Diff view and shortcut-driven flow

Compare original and rewritten text line by line or word by word, and trigger everything from keyboard shortcuts or PopClip integration.

RewriteBar solves a very practical problem for Mac users: most writing assistants live in their own editor or browser tab, while real writing happens everywhere — Slack threads, email clients, Google Docs, Notion, Word, WhatsApp and code editors. RewriteBar instead sits at the system level. It grabs your current selection, sends it to a language model with the action you picked, and pastes the result straight back over the original text, so you never leave the app you are working in.

Out of the box it ships with a library of ready-made actions: grammar and spelling fixes that understand full-sentence context, rewriting for clarity, simplification, tone adjustment, humanizing AI-sounding text, summarising to bullet points, fixing broken JSON, converting to title case, turning formal German or French into the informal register, and translation across 500+ languages. On top of those presets you can build your own commands, insert variables, and chain several actions into one workflow — expand, emoji-fy, translate and summarise in a single pass. A side-by-side diff view lets you check exactly what changed before you accept it.

Flexibility is the other selling point. You can bring your own API key from OpenAI, Anthropic, Google, Groq, Mistral, DeepSeek, OpenRouter and dozens more; subscribe to the RewriteBar Gateway to get access to 70 models without managing keys; or run everything through a local model with Ollama, LM Studio or Apple Intelligence for maximum privacy. The app is only around 25 MB, is natively built for macOS, integrates with PopClip, and never stores your text on RewriteBar's servers.
