Given a need for improved career development of doctoral candidates, we developed a short online course to support career planning. We brought together a large team with relevant expertise to develop a Career readiness course, which was launched mid-2024. This innovative self-paced, fully online course uses an EdX platform and incorporates video and text content, as well as using ChatGPT as a tutor and career adviser. The objecives of this case study are to discuss how the course was developed, including how ChatGPT was incorporated in the course, and to relay preliminary feedback from participants regarding their experiences of ChatGPT as both a tutor and a career adviser. Although there have been some technical difficulties embedding ChatGPT in the course, the inclusion of ChatGPT as both a tutor and a career adviser has received positive feedback from testers and participants. This case study illustrates how ChatGPT can be used to provide personalised, instant and helpful feedback.
