This grammar check service is the fastest at processing your writing to find grammatical errors. Its spell check is accurate and thorough, and it meets all the criteria we looked for in our Accuracy evaluation. Its overall ranking was dragged down because it lacks interactive grammar exercises and a mobile version. Its user interface is not as modern and sleek as our top two products.

CorrectEnglish, developed by Vantage Linguistics, scored 100 percent in our tests. That does not mean that it found every grammar error in our test paragraph, but it did find more than any other online grammar checker we evaluated. We graded them on a curve, and CorrectEnglish set that curve.

Errors and problems it found in our test paragraph included use of articles, capitalization, sentence structure, negatives, numbers, punctuation, spelling, pronoun agreement, subject and verb agreement, use of adverbs, infinitives and more. CorrectEnglish identifies passive voice, improper use of possessives and commonly confused words such as to, two and too, as well as a host of other errors.

Editing & Feedback

CorrectEnglish Complete lets you check your grammar using several style guides. They include MLA (Modern Language Association), APA (American Psychological Association), CMS (Chicago Manual of Style) and CBE (Council of Biology Editors). You can also create new, customized styles.

CorrectEnglish offers a side panel to display mistakes in text that you paste into the editor window. Click on a mistake in the panel and a window pops up with a suggested fix. You can ignore that instance, ignore the rule throughout your text or replace the mistake with the suggested correction. The side panel separates errors into three main categories, Basic Check, for general mistakes, Grammar and Usage mistakes and Style Choice.

At the bottom of the editor window is an informational bar that lists stats from your text. The stats include the number of words, number of sentences, the average words per sentence and a numerical score that measures the reading ease of your writing. It also has a three-tiered meter to judge your writing. The tiers are Poor, Good and Great.

The Writing Tab in the toolbar breaks down your tiered grading even more, assigning a Poor, Good or Great ranking to different writing elements, including Organization, Focus, Content and Style. It also lists revision tips for your writing.

The Reference tab in the toolbar lets you search writing websites. Simply type a word into the search field in the side panel, and links to related writing websites will appear. For example, if you type "love," links to sites on love poems, quotes, greeting cards and advertising appear. The Reference tab also is integrated with Lexipedia, to let you find word definitions easily.

CorrectEnglish lacks interactive grammar exercises and cannot detect plagiarism. It does not offer a mobile version. These deficiencies dragged down its overall ranking.

Ease of Use

CorrectEnglish Complete online grammar check offers all the necessary tools to correct your grammar and usage, as well as an online spell check to correct spelling. It has a simple interface, with a top toolbar and side panel for feedback. It works well, but the interface and pop-up correction box are a bit dated, not modern and sleek like our top two products.

This online grammar checker functions well. It found the most mistakes in our test paragraph in the shortest time. We tested a 340-word paragraph five times for correction speed and averaged the trials. CorrectEnglish had the fastest speed at 2.5 seconds.

Help & Support

In addition to CorrectEnglish Complete's Review tab, which links you to writing websites, this grammar checker offers FAQs in the web edition User's Guide. It offers videos that demonstrate how to use CorrectEnglish and 12 Child Pages for young learners. It has responsive email support and offers telephone support. This online grammar check does not offer live chat.
