Writing Reports

Reports on your text help you see where your content needs improvement.


Grammarly provides you with performance reports that help you know how easy it is to read your text.

Text Scores

The tool measures your text score from one to 100. This score is based on how many types of suggestions were found in your text and how your content compares to others with the same goals.

The higher your score, the fewer the suggestions the tool made.


This section depends on the rare and unique words in your text. Unique words represent how many different words you used in your text compared to other users. On the other hand, rare words represent the percentage of words in your text that are not common English words.

These scores help you see if you need more variety in your vocabulary.
