Quick Overview

ProWritingAid and Quillbot are two recognized platforms that provide students, writers, and general audiences with spell-checking services. We at AcademicHelp used both of them to proofread 3 of our texts. Quillbot turned out to be much more convenient and helpful in detecting mistakes across all the general grammatical aspects. Prowritingaid free website, however, despite being simple in use, could only slightly improve the spelling score of our writing.
