Once you open an article, most library databases offer tools to copy citations. You can usually find this option as part of a tools menu or some kind of icon.
Be sure to check computer-generated citations for accuracy before listing them in your References/Works Cited page, as some may not be 100% accurate.
Citation generators can help you to create citations and works cited/references/bibliographies for your assignments. If you decide to use a citation generator, review your results carefully to be sure the citation is accurate. Some generators contain formatting errors or may not be updated to the latest edition of a particular citation style. If in doubt, refer to the appropriate style manual for definitive information.
