Grammarly: AI Writing and Grammar Checker App 作者： Grammarly

Grammarly for Firefox is your always-on assistant for clearer, more compelling communication. It helps you brainstorm ideas, overcome writer’s block, and refine your writing with confidence, precision, and ease.

Powered by advanced AI, Grammarly does more than correct mistakes. It generates one-click drafts to help you get started, builds organized outlines, sharpens tone for any audience, and adapts to your goals as you write—whether you're working on a school assignment, a business email, or anything in between.

With built-in plagiarism detection and AI content checks, Grammarly supports originality while helping you write faster, sound sharper, and communicate more effectively—anywhere you write online.

➤ How it works

Grammarly works right where you do—in your browser—offering real-time feedback as you type in emails, documents, and more.

It goes beyond surface-level edits by offering suggestions that help you organize your ideas, strengthen your arguments, and tailor your tone to your audience. Whether you’re tightening a sentence or reworking a full draft, Grammarly adapts to your goals, context, and intent in real time.

You can apply suggestions instantly or expand them to see the "why" behind each one—putting you in control and helping you build stronger writing habits with every edit.
