CorrectEnglish positions itself as a teaching proofreader rather than a silent autocorrect. Its engine flags contextual errors, spelling mistakes and weaker word choices, then attaches a short explanation to each suggestion so users learn the underlying rule. A click-to-accept workflow keeps the actual improving of the text in the writer's hands.
The product is delivered mainly through a browser extension for Chrome, Firefox, Safari and Edge, plus keyboard apps for iOS and Android, meaning it works inside webmail, job boards, word processors and messaging apps rather than in a single editor. A web editor adds rich-text formatting, style templates and collaboration basics, while the Originality Detector compares documents against the open web and internal databases to prompt citation where text is not the writer's own.
Beyond correcting individual sentences, CorrectEnglish tracks writing statistics such as word count, sentences per paragraph and readability grade, and offers performance views on organisation, focus and clarity. That makes it a fit for students, job seekers and non-native English speakers who want measurable progress rather than one-off fixes.
