Abstract The current research investigated the effect of digital tools on enhancing English as a Foreign Language (EFL) writing skills of primary stage pupils and their motivation towards writing. The research adopted the quasi-experimental design using a pre/post-test design. The research sample involved 60 fourth- year primary pupils at Al-Foqai Primary School in Al-Manzala city, Dakahlia Governorate, Egypt. The participants were divided into two groups: an experimental group (n=30) and a control group (n=30). The research instruments included: an EFL writing skills test (pre-post), an analytic rubric for assessing the EFL writing skills test, and a motivation scale. One specific digital tool, Grammarly, was employed. The results indicated that the experimental group achieved significantly higher scores in their post-test compared to their pre-test scores as well as compared to the control group's post-test scores in both the EFL writing skills test and the motivation scale. Thus, using digital tools had a large impact on enhancing EFL writing skills of primary stage pupils and their motivation towards writing. The research also proposed several recommendations and suggestions for further research. Keywords: EFL Writing, motivation, digital tools, Grammarly.
