There are three Premium subscription plans available: at $29.95/month, $19.98/month (if paid $59.95 per three months), and $11.66/month (if paid $139.95 per year).Īpparently, Grammarly scans documents against different types of web pages (8 billion of them, according to the developers). The premium account covers a plagiarism detector, advanced proofreading capabilities, and vocabulary enhancement suggestions. Grammarly offers a basic online text editor and browser extension for free. It’s also possible to use the plagiarism feature with the desktop app and a Microsoft add-in (see the picture below). For example, if I write an email in Microsoft Outlook or a message on Facebook, I don’t need to copy and submit them to Grammarly – instead, the app automatically scans them and suggests improvements in real time.

This is especially convenient for those who need to proofread texts regularly. Unlike its competitors, Grammarly is available in many versions: as an online platform, native desktop app, browser extension, and even a Microsoft Office add-in. By combining a thesaurus, automated proofreader and plagiarism finder, Grammarly saves users from having to purchase these tools separately. The software is as good at spotting unoriginal content, as it is at finding grammar, spelling and punctuation mistakes ( maybe even better). Grammarly is rather famous for its proofreading capabilities than the plagiarism detection engine, and it’s probably not fair.
