The research on grammar checking systems has been conducted for a considerable period of time. In recent years, Grammarly has been widely recommended and has garnered impressive acclaim. In November 2022, OpenAI ChatGPT emerged, making a significant impact across multiple research fields. To compare the performances of Grammarly and ChatGPT-based checker, this study utilized example sentences from a renowned reference book called "Common Mistakes in English" (Fitikides, 2002) by Longman. The data set includes 584 typical errors made by non-native English speakers. The results obtained in this study are interesting. In terms of un-English expressions, Grammarly corrected only 22% of the errors, while ChatGPT successfully revised 75% of them. Regarding cases of incorrect omissions, Grammarly corrected only 48.7% of the errors, whereas ChatGPT accurately revised 85% of them. In the areas of misplaced words, Grammarly rectified only 33% of the errors, while ChatGPT achieved an impressive 89% correction rate. In terms of confused verbs, Grammarly addressed only 14.8% of the errors, whereas ChatGPT accurately revised 85% of them. In the case of confused nouns, Grammarly failed to correct any errors, whereas ChatGPT correctly revised 86% of the 21 errors. Finally, for the confusion of parts of speech, Grammarly corrected only 43% of the errors, while ChatGPT achieved a 77% accuracy rate. Based on these results, it is clear that ChatGPT achieves remarkably high levels of accuracy, ranging from 75% to as high as 89%. This result clearly demonstrates ChatGPT's significant improvement in precision when correcting ESL errors.
