WWDC 2025 signaled the start of Apple's most ambitious AI initiative yet. Over the past year, the company has gradually introduced Apple Intelligence capabilities to iPhone, iPad and Mac devices. This includes enhancing Siri's functions, incorporating generative features into essential applications and providing developers with fresh opportunities to create AI-driven solutions.

As Apple readies for WWDC 2026, set to begin Monday, June 8, the firm confronts another key shift: its post-Tim Cook period. Cook's last day as Apple CEO falls on August 31, following 15 years in the position. Hardware Engineering lead John Ternus will assume the role from Cook, so the leadership handover will align closely with Apple's yearly September hardware showcase.

Combined, Apple's AI rollout and executive changes will shape the next phase of the company's direction and lineup of devices and services. Until then, let's look back at Apple's key AI releases since WWDC 2025 and what Tim Cook's exit signifies for the firm.

Apple Intelligence becomes a core platform feature

Instead of debuting as an independent offering, Apple Intelligence has developed into a system-wide element integrated across iOS, iPadOS and macOS. The platform delivers generative writing aids, intelligent summaries, contextual recommendations and more fluid Siri interactions straight into Apple's operating systems.

Apple's aim appears to be speeding up routine tasks while keeping much of the computation on-device and upholding Apple's privacy-centered stance.

Siri gets smarter and more personalized

One of Apple's biggest AI advancements over the last two years has centered on Siri. The refreshed assistant can pull data from apps like Mail, Messages and compatible third-party services to handle multi-step requests. Users can direct Siri to locate details hidden in chats, compose replies or perform actions that once meant switching between several apps.

To broaden Siri's reach, Apple added selective connections with third-party AI models for queries that might gain from outside systems. This method lets Apple blend its platform smarts with wider AI functions while preserving a consistent user experience.

Apple has reportedly been developing a Siri app, a fresh interface and more advanced AI capabilities, which may point to the launch of its largest update yet at WWDC 2026.

AI comes to Apple Messages, Mail and Photos

Apple has directed much of its AI work toward the apps users rely on daily. Messages and Mail now include AI-created summaries that turn long exchanges and email chains into brief, easy-to-scan recaps. Apple has also added user settings that control how and when AI processes content.

Photos has received generative editing options, such as the power to clear unwanted elements, swap backgrounds and build highlight reels from photo collections. More complex jobs can draw on cloud models while keeping familiar editing steps intact.

New creative tools for content creation

Apple has grown its AI-powered creative options across its media platforms, aiding users in making videos, presentations and other material with reduced manual effort. Tools like AI-supported scene picking, storyboarding and music generation aim to simplify production while fitting into existing flows in Final Cut Pro and iMovie.

The updates show Apple's wider push to open advanced creative options to both pros and everyday creators.

What Tim Cook's departure could mean for Apple's future

Tim Cook's exit marks one of the biggest leadership shifts in Apple's history.

While Apple's core long-term plans are unlikely to shift right away, fresh leadership will probably affect how boldly the company chases AI projects, strategic alliances and new hardware areas, such as AI wearables and glasses. The change may also speed up choices on custom AI chips, upcoming device experiences and the speed of product releases.

At the same time, leadership moves can spark short-term questions as investors, developers and longtime customers seek clues on how a new team will guide Apple's focus ahead.

WWDC 2026 is expected to expand on the base Apple built over the past year. Likely reveals could cover deeper AI ties across system tools, new developer resources for creating AI agents and an updated Siri. Whether the spotlight lands on software, hardware or both, WWDC 2026 should show how Apple intends to compete in a field increasingly shaped by AI.
