KZAI (103.7 FM) is a radio station broadcasting a Christian Worship format through the nationally programmed Air1 network. The station is licensed to Balcones Heights, Texas, United States, and serves the San Antonio area. The transmitter is located in San Antonio proper, due north of downtown and adjacent to Interstate 10. KZAI is owned by the Educational Media Foundation.^[3]

Originally a station in the Corpus Christi area, the station moved in 2021 as part of a facilities shuffle that moved a third EMF signal into San Antonio (alongside existing K-Love outlet KZLV and rimshot Air1 outlet KZAR). The former 103.7 facilities and KXAI call sign were moved to another license, leaving Air1 programming seamlessly available to Corpus Christi-area listeners.
