Many of the important technologies of the coming decades, from ultra-precise clocks and quantum computers to sensors that may detect the elusive dark matter that fills the universe, depend on accurate knowledge of how individual atoms and molecules behave. Today, this knowledge is scattered across thousands of scientific articles, supplementary documents, and aging databases. No single trusted resource brings together the best computer-calculated values and the most accurate laboratory measurements. The result is that researchers and engineers waste considerable time searching for, checking, and re-checking information that they need to design experiments, build new instruments, and interpret their results. This project addresses that problem by expanding a free public online platform, already used by thousands of researchers worldwide, into a comprehensive scientific data resource. New features include broad coverage of atoms and molecules important for emerging quantum technologies, automated software that continuously reads scientific literature and extracts trustworthy numerical results, and a conversational interface that allows users to pose detailed scientific questions in plain language and receive properly referenced answers. The platform accelerates discovery in academic laboratories and supports the quantum technology industry. Students who participate in the project receive valuable training at the intersection of physics, computer engineering, and modern artifici
