QuillBot helps students save time during the writing process, enhances their vocabulary, and assists with various aspects of academic writing such as complexity, objectivity, formality, and hedging. However, the negative effects include a tendency for students to become overly reliant on QuillBot, leading to reduced effort and less use of their own writing skills. Additionally, students faced challenges with QuillBot, such as poor network connectivity and unclear instructions for upgrading to the premium version. Baron et al. indicate that students gave some positive feedback. Many students are aware that the QuillBot application is a reliable tool for checking grammar, making it easier and more convenient for them to ensure their writing is free of grammatical errors. Consequently, the researcher concluded that using QuillBot is beneficial for enhancing students' grammar skills. Latifah et al. reveal that although users appreciate QuillBot's Journal IJCIS homepage - https://ijcis. net/index. php/ijcis/index ability to save time, there are concerns about its potential to foster overreliance and hinder the development of critical skills. QuillBot substantially improves writing quality and efficiency by identifying errors, paraphrasing content, and enhancing It also helps overcome language barriers and address plagiarism issues. However, its role as a supplementary tool rather than a replacement for independent writing and critical thinking was emphasized, with a warning against excessive Consequently, additional research is needed to explore its impact on academic performance, its effectiveness in various linguistic contexts, and its role in writing instruction. Despite extensive research on various online grammar check applications like Grammarly. ProWritingAid. WhiteSmoke, and QuillBot, there remains a significant gap in understanding QuillBot's specific impact on assessing and improving students' writing errors in English essays. Although studies such as Ho . and Fitria . compare QuillBot with other tools, a detailed comparison of QuillBotAos unique effectiveness in error correction across different writing issues, relative to its competitors, remains lacking. Furthermore, while research by Latifah et al. raises concerns about potential overreliance on QuillBot and its effect on critical skill development, there is limited investigation into how QuillBot specifically influences the enhancement of critical thinking and independent writing skills in academic settings. Additionally, while QuillBot's benefits in grammar correction and vocabulary enhancement have been documented . Amanda et , 2. , there is a need for research exploring its performance across various linguistic contexts and proficiency levels, particularly among non-native English speakers. Longitudinal studies on the longterm impact of QuillBot on academic performance and writing proficiency are also scarce, leaving a gap in understanding its effects over time. Finally, while existing literature highlights both positive and negative user experiences . Jaladara et al. , 2023. Baron et al. , 2. , there is a need to explore how QuillBot can be effectively integrated into writing instruction and feedback processes to maximize its benefits while addressing potential drawbacks. This research seeks to fill these gaps by providing a comprehensive evaluation of QuillBotAos effectiveness in assessing and improving students' English essay writing and offering new insights into its role in academic writing instruction. This study aims to evaluate the use of QuillBot in assessing and improving students' written English grammar results. The main focus of this research is to understand the Page 3 International Journal of Computer and Information System (IJCIS) Peer Reviewed Ae International Journal Vol : Vol. Issue 01. January 2025 e-ISSN : 2745-9659 https://ijcis. net/index. php/ijcis/index extent to which QuillBot is effective in detecting grammatical errors and providing useful suggestions to students. By providing insight into the use of QuillBot in checking grammar, it is hoped that this research can contribute to the development of more effective learning strategies and tools to improve the quality of student writing.
