Refine and Correct Your Sentence
Corrects Comma Splices
The checker identifies and fixes comma splices. Change “He loves cooking, he often experiments with new recipes” to the grammatically correct “He loves cooking; he often experiments with new recipes.” No more pesky comma splices!
Detects and Corrects Punctuation
The checker suggests where to add necessary punctuation like commas, semicolons, or periods.
It may recommend adding conjunctions (like ‘and’, ‘but’, ‘although’, etc) to connect clauses properly. For example, in “I was tired I still finished the project,” the tool might suggest “I was tired, but I still finished the project.”
The tool suggests splitting a run-on sentence into two or more separate sentences. From “She enjoys painting her artwork is quite impressive,” it would make two sentences: “She enjoys painting. Her artwork is quite impressive.”
