With iOS 26.4, CarPlay users will be able to use third-party chatbots with CarPlay. AI services such as Claude, Gemini and ChatGPT will be accessible through the CarPlay system for the first time.
The Apple CarPlay Developer Guide (PDF) lists voice conversational apps as a supported app type starting with iOS 26.4. Apple is implementing a new voice control screen that will allow apps to provide visual feedback for voice conversational apps.
AI apps that integrate CarPlay will need to add support for the voice control screen when voice services are active. There is a special requirement for voice-based conversational apps, and companies that build chatbots will need to update their apps to add CarPlay support.
CarPlay has long supported third-party apps, but Apple limits the kinds of apps available to ensure drivers aren’t distracted in their vehicles. Companies like Anthropic, OpenAI, and Google have not yet been able to create CarPlay apps, limiting CarPlay users to Siri voice control in the vehicle.
The new integration will allow CarPlay users to access voice-based apps like ChatGPT to ask hands-free questions, but the apps won’t be able to control vehicle or iPhone functions. There will also be no wake word option to activate a third-party app, so users will have to open the app to use the chatbot. Upon launching the app, a customizable voice control screen will present users with vehicle-optimized chatbots.
iOS 26.4 is currently in beta and is expected to be released this spring.
