This study explores the potential of No-Code (NC) platforms to enable people with disabilities to develop customized workplace tools. While NC platforms allow individuals without IT experience to create applications, their usability for people with disabilities has been underexplored. Conducted in collaboration with a sheltered workshop in Germany, the study consisted of three phases. Phase I consisted of a collaborative brainstorming session with employees to understand the requirements and shape the study design. In phase II, six participants with cognitive or developmental disabilities received one week of training to develop chatbots. Each participant successfully created four chatbots: a Vacation chatbot, a Suggestion Box chatbot, an online Cook-book chatbot and a Sickness Registration chatbot. In Phase III, the chatbots were implemented in the sheltered workshop and used for a period of approximately 5 months. Usability was assessed at various intervals using the System Usability Scale (SUS), delivered in chatbot format. The average SUS score was 88.9 (SD = 11.2), indicating high user satisfaction. Participants particularly valued the use of image-based interfaces, which enhanced accessibility. The study concludes that with targeted training, people with disabilities can effectively use NC platforms to develop functional, accessible tools that meet the needs of their work environment.
