Table 2: Methodology. data. Additionally, the recommendations which are given by AI are available through REST or GraphQL protocol. These data are retrieved by the frontend to display real-time feedback to the users. The role of AI in improving the process of decision-making is crucial for this app because it incorporates efficiency, analyzes historical data patterns, and offers insights which are helpful. Furthermore, in this process, the frontend implementation of the platform is designed in a way that focuses on security, user-friendliness, and interactive feedback. The user interface uses intuitive navigation, real-time validation, and secure data transmission between the frontend and backend. Features are designed in a way that they can provide immediate feedback and smooth interaction with the backend, for example, user registration, voting, task management, and decision creation, and all of these processes help in ensuring a seamless experience for the user. In the frontend, there are different kinds of functions, for example, the registration and account management system. This system in the app is used so that the users can register, activate their accounts, and manage their profiles. Similarly, a voting feature is present in the app which allows users to upvote, downvote, or retract votes for different decisions.
