Quillbot: AI Writing Assistant with Humanizer, Paraphraser & AI Detector

Quillbot for Chrome is a multilingual AI writing assistant extension that helps you write clearly, quickly, and with more control, right where you work. This AI writing assistant combines a Grammar Checker, Humanizer, AI Detector, Paraphrasing tool, and AI writing tool to improve your writing in real time. From quick emails to full drafts, Quillbot helps you say what you mean without overthinking it. ➤ How It Works Install the extension and keep writing like you normally do. Quillbot works in the background, ready when you need it. Write in any text field across the web, then highlight text or open the toolbar to get instant suggestions. You can fix grammar, humanize your text, check it for AI flags, use the sentence rewriter to adjust phrasing, or generate new text with the AI text generator. Everything happens in one place, so you don’t have to copy, paste, or switch tabs. ➤ Privacy and Data Safety Your writing is personal. We treat it that way. Quillbot processes only what’s needed to provide suggestions and does not sell your data. Our systems are designed with modern security standards in mind, and we continuously improve how we handle and protect user information. You stay in control of what you write and what gets changed. ➤ Key Features A writing productivity tool that does more than just fix typos; it helps you communicate better. ✓ AI Writing Assistant Get real-time suggestions as you write.
