It checks English grammar and agreement, spelling, punctuation, repetition, and selected style patterns, then shows the position and suggested replacements for each finding.
How do I read an individual finding?
After checking, hover over or focus a highlighted phrase in the text. The inline explanation shows the category, the issue, and suggestions without taking you away from the passage.

Does Grammar Coach give an exam score?
