AV Word uses the AV SDK provided by AV Text Ministries. AV Word is the first software to make use of the AV Transformation (AV-T) that is part of the AV SDK. AV-T is a modern transformation of the AV Text. As many of you already know, the Authorized Version (AV) is widely known as the King James Version (KJV). So it is realistic to consider AV-T as a modern update to the KJV. See the AV Text Ministries site for details.
AV Word software is designed for Windows and Mac. The Web variants of AV Word is also expected to support iOS and Android devices. Stay-tuned as we're busy writing the apps.
