What is Grammar Checker?
Grammar Checker is a lightweight writing-assistance tool for Chrome users, capable of detecting grammar mistakes, spelling errors, and stylistic problems in real time. It not only identifies basic spelling errors but also uncovers advanced issues such as confusing 'there' with 'their,' misusing 'a' versus 'an,' and repeating words. Users can conveniently invoke the checker by right-clicking on any selected text on any webpage. The interface shows real-time word and character counts (with spaces serving as word separators) and retains the entered content even after closing the page, making it easy for users to continue editing.
