- Visual Intelligence, which allows users to take action on whatever they see on the screen, whether it be searching products, adding events to their calendar or even talking to ChatGPT. enquiries regarding what is being exhibited.
- Intelligent Shortcuts that instigate functions such as summarization of emails, creation of pictures, or writing of text with context awareness.
