Computer-assisted personal interviewing (CAPI) is an interviewing technique in which the respondent or interviewer uses a computer to answer the questions. It is similar to computer-assisted telephone interviewing, except that the interview takes place in person instead of over the telephone.

This method is usually preferred over a telephone interview when the questionnaire is long and complex. It has been classified as a personal interviewing technique because an interviewer is usually present to serve as a host and to guide the respondent. If no interviewer is present, the term Computer-Assisted Self Interviewing (CASI) may be used. An example of a situation in which CAPI is used as the method of data collection is the British Crime Survey.
