Free Online Grammar Checker List

Vote for the best free online grammar checkers! (full list with links, detailed reviews and more)

Grammar checker is a necessary tool for any online article writer. Better than spell-check, most of them demand payment or require a download. I’ve selected a list of free online grammar checkers, ranked by their design, functionality and ease of use.

Grammarly

A free grammar checker popularized by Google’s ads, Grammarly requires no special introduction. Both paid and free software users can copy their content to the online proofreader screen and take their articles through an instant grammar check.

Grammarly is the most versatile proofreading tool.

Before running a grammar check, you can choose between several categories, such as business, academic, technical, creative or casual writing. Each style is reflected on the analysis, allowing the most specialized treatment between different kinds of articles.

PaperRater

Made with the most relevant proofreading tools in mind and a good-looking design, this free online grammar checker falls short of several advanced mistake detection abilities when it comes to direct competition with websites such as Grammarly. Nevertheless, PaperRater is completely free and seems to make up for the lack of grammatical insight with some of its analytical features.

PaperRater provides detailed stats for your text or article.

It requires some extra information before displaying a report, but uses it well to analyze your text, be it an online article or a school paper. In respect to its proofreading ability, however, it’s not that different from the basic grammar check of Microsoft Word. If you’re looking for a rigorous grammar check for your articles, you should probably look at other websites like Grammarly.

GrammarCheck

Chosen for this list exclusively for its ease of use, GrammarCheck.net is a tool that covers your most basic proofreading needs and is completely free of charge. Offering numerous links to helpful articles on English grammar, it puts an emphasis on learning and improving your grammar skills, instead of mindlessly pushing your online articles through grammar checkers.

SpellChecker

SpellChecker.net looks good enough to be your first stop for casual grammar checks for your smaller texts. On the other hand, your more serious papers and articles should probably be submitted elsewhere for automated proofreading, as many less noticeable mistakes have managed to escape this aptly named spell checker’s vigilant eye.

SpellCheckPlus

SpellCheckPlus.com is good at catching the basic grammatical errors in your articles, not unlike PaperRater (or Microsoft Word, for that matter). However, as a free online proofreading utility, it leaves much more to be desired and seems less efficient when compared to websites like Grammarly.

Proofread your content!

Even though free online grammar checkers have made it much easier to keep track of grammar mistakes in your articles, you shouldn’t put too much trust in their performance. Minor mistakes visible only to human readers might escape grammar tools like PaperRater and Grammarly. Manually proofreading your articles is always a good idea, as you shouldn’t put too much trust in free online grammar checkers. And most of all, keep writing articles!
