Scrub.it is an AI-powered Chrome extension that eliminates the friction of prompt engineering by letting users refine text directly where they type. Instead of copying text between websites and AI chatbots, users simply select text, press a shortcut, and instantly receive an optimized version inside the same input field. The extension intelligently adapts prompts for different AI models, including ChatGPT, Claude, and Gemini, while allowing users to customize tone, writing depth, and formatting preferences. Whether you're writing emails, coding, creating content, translating text, or preparing AI prompts, Scrub.it helps produce higher-quality outputs with fewer iterations. Built with Manifest V3, React, TypeScript, Tailwind CSS, and Zustand, Scrub.it is designed for performance and privacy. The extension uses lazy loading to avoid impacting browser performance, Shadow DOM to isolate its interface from host websites, and local storage to securely keep API keys and user preferences on the user's device. Rather than acting as another AI chatbot, Scrub.it integrates seamlessly into existing workflows, enabling users to improve their writing without breaking focus or switching tabs. By removing the "copy-paste prompt tax," Scrub.it makes interacting with AI faster, smarter, and more natural.
