Grammarly

Grammarly is a writing assistant that checks text for grammar, spelling, and punctuation errors as you type. It works in a web editor, as a browser extension, and inside apps such as word processors and email, offering suggestions with a short explanation for each correction. Users can accept or ignore each suggestion, keeping control over the final wording. It is widely used for emails, essays, reports, and everyday messages.

Beyond basic corrections, Grammarly can suggest clearer wording, point out wordy sentences, and flag tone that may sound too formal or too casual for the reader. Paid plans add more detailed style and clarity suggestions, as well as checks for originality in longer documents. The tool does not write the text for the user; it improves what is already written. Users should still read the final version, since no checker catches every nuance.

Students use Grammarly to polish essays and assignments, while job seekers use it to check CVs and cover letters. Professionals use it for client emails, reports, and presentations, and writers use it to catch small errors before publishing. It is a good fit for anyone who writes in English and wants a quick, reliable second check.
