The Impact of Grammarly Software on Enhancing Writing Skills among EFL Learners

In light of ongoing challenges in writing education and the needs of digital-native learners, this study explored the effectiveness of using the free version of Grammarly in the writing development of EFL learners. Thirty-three TEFL students at Shahid Rajaee University were randomly selected and participated in the study. Using a quantitative one-group design, their writing performance was assessed through six tasks and analyzed via one-way Repeated Measures MANOVA. The results indicated a consistent improvement in overall writing performance through the regular use of Grammarly as an automatic corrective feedback tool. To identify which writing components improved, an RM-MANOVA was conducted on grammar, spelling, punctuation, and clarity. The analysis showed significant improvement only in grammatical accuracy, with other aspects remaining unchanged. These findings highlight Grammarly’s potential in enhancing grammatical skills. The study contributes to ELT by encouraging the integration of ICT-related content into the EFL curriculum and teacher training programs, emphasizing the role of AI tools in language learning. These findings highlight the increasing impact of AI-powered tools in improving writing skills for language learners. Educators should balance automated feedback with personalized instruction. As research on effectiveness of Grammarly is still limited, further studies are necessary to fully understand its educational potential.
