<p dir="ltr">In an era where digital communication is important, Chinese English speakers face unique challenges in text-based academic settings, struggling to accurately convey emotions and tones. This study investigates the impact of AI-powered emotion analysis services (like ChatGPT with prompts) in addressing these challenges. It aims to enhance the writing and emotional expression skills of non-native English-speaking university students through AI assistance in text-based communication. Participants will engage in tasks with professors and peers as the target audience to assess the AI tool's effectiveness in adapting writing styles and improving emotional clarity. The findings highlight the potential of AI and emotion analysis services in improving email writing and emotional expression. We concluded that with the assistance of AI tools, people can perform better in email writing and emotional expression. However, there is a contradiction in the data we collected to our original hypothesis, indicating no significant differences in editing behavior with AI assistance. A discussion about ways to provide emotion analysis services is included as well. </p>
