In an era where artificial intelligence (AI) is reshaping education, its role in second language (L2) or Foreign Language (FL) writing instruction is becoming important. This chapter explores how AI-supported tools, particularly ChatGPT, are influencing writing practices in EFL classrooms. This chapter builds on the main writing instruction methods product, process, and genre approaches and explores both the benefits and challenges of using AI in writing. It also looks at how technology connects with key areas like feedback, creativity, independent learning, and digital skills. While traditional teacher feedback remains essential, AI tools offer real-time support that can enhance student engagement, self-expression, and revision skills. The chapter also addresses practical implications for classroom use and ethical considerations. Ultimately, it argues that when AI tools are used carefully, they can complement rather than replace the human feedback in language education.
