The emergence of Artificial Intelligence is drastically changing the creative process of generating new ideas, which is called “ideation”. The aim of the research is to study its impact on the “ideation” phase at the individual level. Ten students from Engineering schools participated in two activities that measured the characteristics of divergent-creative thinking: “fluency”, “flexibility”, and “originality”. The first activity was Guilford's Alternative Uses Test (AUT), and the second was a Creative Narration technique. The students were divided into two groups, and one of the groups collaborated with ChatGPT (GPT 3.5). From the data analysis, it was found that in the Guilford's Alternative Uses Test (AUT), Artificial Intelligence significantly enhances “fluency” and “flexibility” and considerably enhances “originality”. However, in the production of a creative text, the research showed no enhancement of the above characteristics. A possible cause is identified in the different degree of experience in creative writing of the students who collaborated with ChatGPT (GPT 3.5), and therefore in the different way they provided prompts. In conclusion, Artificial Intelligence can prove to be a valuable collaborator in the “ideation” phase, but its effectiveness depends on the users’ experience in prompting techniques.
