CAD can refer to either of two devices:
- The Canon Analysis Device, used to analyze canon characters and determine their OOC level, and to detect possession and Character Replacements.
- The Character Analysis Device, used to analyze original characters and detect Mary Sues.
There are also a number of varieties of Combined CAD, such as the DOGA CAD and the SIELU CAD. In recent years, Combined CADs have become more common than the separate models, and are referred to simply as CADs.
In the Original Series, CADs are described as being a "handheld computer" with a "tiny readout" and, when directed at a Sue, displaying "urgently flashing red letters". A CAD's beeping increases in volume proportionately to how bad the disruption to canon is, and prolonged use can wear them out, usually resulting in an explosion.
CAD readings differ depending on the CAD model.
