Apple's iOS 26.4 has added a new category of CarPlay apps called 'voice-based conversational apps', allowing AI chatbots to live in CarPlay. The move is significant as these capabilities have been inaccessible for driving. In addition, Apple introduced iPhone-style widgets to CarPlay for the first time and added Ambient Music, which allows users to create moods based on moods. The release of video in the car is expected to take a slow rollout due to a requirement for automakers to approve its vehicles.
