Scraib.app

Scraib.app is a ChatGPT overlay tool that rewrites selected text in any Mac app with Control + R. A Mac menu bar app that rewrites selected text in any application with Control + R. Custom tone rules can be global or per app, and you can run it on your own API keys from ChatGPT, Claude, Gemini, Ollama and others.

Scraib.app is a menu bar utility for macOS that rewrites whatever text you have selected, in whatever application you happen to be using. The workflow is deliberately small: highlight a sentence or paragraph, press Control + R, and the selection is replaced with a cleaned up version. There is no chat window to open, no prompt to retype, and no copy and paste round trip between your editor and a browser tab. The app was built by a solo developer who wanted exactly that shortcut for everyday messages and documents. Style control is the core idea beyond the hotkey. You define rules that describe how you want your writing to sound, and those rules are applied every time you trigger a rewrite. Rules can be set globally so the same voice follows you across tools, or customised per application, which is useful when a casual tone suits Slack but a formal one suits Outlook. The homepage presents Slack, VS Code and Figma as examples, and the wider icon set suggests coverage across mail, office suites, browsers, note apps and design tools rather than a fixed list of supported destinations. Privacy is handled by letting you choose the AI backend. Instead of routing everything through Scraib's own service, you can supply API keys for ChatGPT, Claude, Gemini, Grok, LiteLLM or OpenRouter and pay those providers directly. Ollama is also supported, so the rewriting can run against a local model when text should not leave the machine. That makes the app plausible for people working with client material or internal documents who would otherwise avoid cloud writing assistants. It sits closest to system wide grammar and rewrite helpers, but leans toward fast, in place correction over long form editing. Anyone who writes in a second language, drafts a lot of short messages, or just wants fewer mistakes in day to day text is the obvious audience. It is a Mac only product, so Windows and mobile users need to look elsewhere. Pricing is a 7 day free trial followed by a $3.99 monthly subscription, or a $10 one time unlock if you bring your own API keys and pay your chosen provider separately.
