Acerca desta extensão
Grammarly for Firefox offers real-time suggestions—including generative AI, grammar check, and more—to help you improve your writing online, no matter what you’re working on.
With comprehensive feedback on spelling, grammar, punctuation, clarity, and writing style, Grammarly is more than just a proofreader. It’s a tool that helps you write with confidence, find the best words to express yourself, and communicate your ideas with ease. Grammarly’s generative AI capabilities allow you to produce instant drafts, ideas, replies, and more wherever you do your best, most important writing.

➤ Terms and Conditions
By installing the extension, you agree to and acknowledge:
www.grammarly.com/terms
www.grammarly.com/privacy-policy

➤ How it works
Grammarly analyzes your sentences as you write and adds color-coded underlines to words and phrases where you can improve your writing. You can apply Grammarly’s suggestion with a single click, or expand the suggestion to learn more about it.

➤ Go beyond grammar
Grammarly’s advanced spelling checker and grammar checker go far beyond the built-in tools of word processors. Grammarly can detect not only misspellings but also commonly confused words used in the wrong context, like “affect” and “effect.” In addition, it can flag and fix complex grammar and punctuation issues like sentence fragments, comma splices, and subject-verb disagreement.

But great writing is about much more than just grammar and spelling. That’s why Grammarly also helps you streamline wordy phrases and rewrite sentences that are likely to confuse readers. It also suggests word choice improvements to help keep readers engaged, and helps you adjust your tone to ensure you come across the way you intend.

For students: Available on the extension, our free auto-citations feature generates citations for online sources in seconds, without you having to enter any info manually or leave the web page. Get pre-formatted citations ready to go, whether you use APA, MLA, or Chicago.
