Apple’s iOS 27 introduced a multi-artificial intelligence extension architecture that allows users to set Anthropic’s Claude as a default assistant on iPhone for the first time, according to product announcements cited in reporting. The system opens Apple’s mobile platform to third-party AI providers beyond its in-house tools.
Extension frameworks let applications plug into system-level shortcuts, messaging and voice interactions. Offering Claude as a selectable default marks a notable shift for a company that historically tightly controlled core user experiences.
Anthropic competes with OpenAI, Google and others in the market for consumer and enterprise assistants. The summary did not detail pricing, regional availability or data handling differences between integrated providers.
Developers will need to adapt software to the new extension APIs as iOS 27 rolls out. Analysts said the move could intensify distribution competition among model makers seeking mobile prominence.
Additional provider partnerships beyond those announced were not specified.
iOS 27’s multi-AI extension architecture marks the first time iPhone users can set Anthropic’s Claude as a default assistant. Apple historically restricted core assistant functions to its own software, making the extension system a notable opening for third-party AI providers on mobile devices.
