Apple's Worldwide Developer Conference kick-off event was packed with announcements

Apple's nearly two-hour-long Worldwide Developer Conference kick-off event was packed with announcements.
The biggest news was the introduction of Apple's own artificial intelligence model, Apple Intelligence. This model will use users' personal information from their devices to answer questions, all while maintaining privacy.
Here are some of the highlights from today's event, which also included operating system upgrades for iPhones, iPads, Macs, and more.
Siri gets smarter: With Apple Intelligence, Siri can answer questions using information from multiple apps. For example, it could prepare you for a meeting by telling you the time and location from your calendar, summarizing a prep document from an email, and giving you the weather forecast.
AI-generated emojis: Apple Intelligence allows users to create their own emojis with text prompts in iMessage and generate non-photorealistic images to send in conversations.
OpenAI Partnership: Apple will let users opt-in to using ChatGPT in situations where OpenAI's technology is better suited to answer questions. The integration works directly from an Apple device, even if the user doesn't have a ChatGPT account.
Hidden apps: New privacy updates for iPhone will let users "lock" certain apps so only they can open them using Face ID, Touch ID, or their passcode. Users can also "hide" apps so they don't show up on their home screen and no media from those apps appear elsewhere on their device.
Real-time call transcripts: iPhone users can now record and create transcripts of calls directly from the phone app. All parties on the call will be notified when it is being recorded.
Gesture controls for AirPods: New gesture controls will allow AirPods users to answer or decline a call with just a nod or shake of their head.
Apple Watch health monitoring: New vital sign tracking on Apple Watch can notify users if they may be getting sick, based on signals like body temperature and heart rate.
