Siri in iOS 27 debuts with a standalone AI-powered app and chatbot-style interactions to better compete with other assistants.

iCloud by default keeps history across devices signed into the same Apple ID, though some short queries may not be saved.

Users can manage conversation history by searching, switching views, and pinning, renaming, or deleting conversations, with an option to erase history in Settings > Siri > Keep Conversations (30 days, 1 year, or forever).

Availability is limited to iPhone 15 Pro and later, with older models sticking to traditional Siri; regional restrictions limit use to English and exclude the EU and China.

Siri can be used in three ways: via the Dynamic Island search box, the side button, or a dedicated Siri app for conversational use.

The Siri app stores conversation history via iCloud, supports media-rich responses, and allows adding context using images or documents.

iOS 27 is in public beta with a fall release window; developers and testers can join the Beta Software Program, and users are advised to back up before testing beta.

After updating to iOS 27, users may be prompted to enable Siri AI, with some on a waitlist from minutes to days.
