In the digital era, business and investment have experienced significant changes. Bali Investment Club is taking a step forward in using artificial intelligence technology in their investment business. Bali Investment Club is focused on getting the best results for its members as they support the New Paradigm initiative. The business entity decided to develop an investor portal operating system that uses artificial intelligence and a framework that reflects their place of business. The ReactJS framework is used for a responsive and interactive user interface on the client side, while the NodeJS framework functions as a web server that responds to API requests from Express. This information system uses MongoDB as a database. The connection between the NodeJS web server and the MongoDB database is managed using the Express framework backend. Artificial intelligence uses Codex and GPT-3 smart agents. The project was developed using the waterfall method. In creating this system, the planning and design concept goes through the data collection stages in the form of interviews, Data Flow Diagrams (DFD), Entity Relationship Diagrams (DFD) and implementation. Usability testing was carried out on the interface and user experience, gray-box testing on the system, and user acceptance testing by the company. The results of research and development prove that an investor portal information system has been developed and tested that works optimally, and with artificial intelligence and a framework that reflects the Bali Investment Club.
