The present research offers an assessment of the online open source tools used in the L2 academic writing, teaching, and learning environment. As fairly little research has been conducted on how to best use online automated proofreaders for educational purposes, the objective of this study is to examine the potential of such online tools. Unlike most studies focusing on Automated Writing Evaluation (AWE), this research concentrates only on the online, open-source writing aide, grammar, spelling and writing style improvement tools available either for free or as paid versions. The accessibility and ability to check language mistakes in academic writings such as college-level essays in real time motivates both, teachers and students. The findings of this empirical-based study indicate that despite some bias, computerized feedback facilitates language learning, assists in improving the quality of writing, and increases student confidence and motivation. The current study can help with the understanding of students' needs in writing, as well as in their perception of automated feedback.
