How Apple Intelligence is changing the way you use Siri on your iPhone
What personal context actions can Siri perform with Apple Intelligence?

With Apple Intelligence, Siri can perform personal context actions such as finding a recipe shared by a friend in a text or email, locating your passport number from your device, understanding and taking actions based on your current app screen, and taking actions in and across apps1. This enhances Siri's ability to understand and respond to your unique needs and preferences.
Is a ChatGPT account necessary to use Siri's new features?

No, a ChatGPT account is not necessary to use Siri's new features. The integration of ChatGPT into Siri allows users to access its capabilities without needing a separate account. However, those who already have a ChatGPT Plus subscription can connect their accounts to access additional paid features within the experiences.
What new features will Siri gain this fall?

Siri will gain several new features this fall, including integration with OpenAI's ChatGPT, personal context awareness, enhanced language understanding, the ability to type instead of speaking to Siri, product knowledge, and on-screen awareness. These updates aim to make Siri a more capable and intelligent digital assistant.
