Clairvoyance concerns hidden or distant information; precognition concerns information about a future event. Reports can be ambiguous, but the intended target separates the terms.

Clairvoyance
Clairvoyance is the claimed ability to perceive a person, object, place, or event beyond the normal range of sight. The term became common in nineteenth-century Spiritualism and later parapsychology. Researchers have tested related claims through card guessing, remote-viewing tasks, and controlled-choice experiments, but results have not produced a broadly accepted demonstration of a paranormal faculty.
Precognition is the claimed acquisition of information about a future event through means other than inference or ordinary prediction. Reports often take the form of dreams, sudden impressions, or a feeling of warning. Because memorable matches are easier to notice than misses, careful study must account for coincidence, selective memory, flexible interpretation, prior knowledge, and the large number of predictions people make.
