This study presents the development and evaluation of RekaCiptaCerita, an artificial intelligence-assisted storytelling tool designed to enhance students' writing skills by exploring axiological dimensions. The tool integrates advanced AI algorithms to provide real-time feedback, suggestions, and creative prompts, aiming to improve students' narrative construction, vocabulary, and overall writing proficiency. An experimental methodology was employed, involving a controlled study with students from diverse backgrounds. Participants used RekaCiptaCerita over eight weeks, during which their writing skills were assessed through pre- and post-intervention tests. The experiment aimed to measure the tool's effectiveness in enhancing writing abilities and fostering an understanding of ethical, aesthetic, and moral values in writing. Results indicated significant improvements in students' writing skills, including enhanced creativity, coherence, and stylistic sophistication. The incorporation of axiological dimensions in the AI tool promoted critical thinking and ethical awareness, enabling students to produce more meaningful and reflective narratives. Students reported that the AI-assisted tool not only helped them structure their stories better but also encouraged them to consider deeper philosophical questions related to their narratives. Future research should explore the long-term impacts of such tools and their applicability across different educational contexts. RekaCiptaCerita can be accessed via https://rekaciptacerita.my.id.
