Both citation builders and managers rely on metadata to create their citations. Metadata is descriptive information about items that is usually hidden in the background, such as in the source code. If an item has good metadata, citation builders and managers will generate perfect, or near perfect, citations. However, poor metadata means poor citations. If information is missing in the metadata, it will be missing in the citation. If there's a typo in the metadata, there will be a typo in the citation. This does not mean don't use builders or managers, it just means that you always need to double check their work.

The auto-generated citation above contains two errors due to errors in the metadata: 1) The article title is all caps, and 2) "Technology" is misspelled. These need to be quickly corrected before turning in your paper.
Citation builders are programs that can help you create your citation. In most cases, you simply type in the information the program asks for (author name, title, etc) and hit the submit button. The program will create a citation for you that you can copy and paste into your document. Some builders will autogenerate citations based on just a title or URL. While this can be very helpful, there are sometimes multiple versions of the same resource (such as reprints). Make sure to select the same version of the resource as the one you're actually using.

Citation managers are extremely useful tools for any research project. Managers allow you to save resources as you conduct research, allowing you to organize your resources and return to them at a later date. They also generate citations based on available metadata (title, author, etc) and contain plugins that import in-text citations and bibliographies directly into your papers.
