When Apple introduced Apple Intelligence at WWDC 2024, it promised a deeply personal AI integrated into every corner of iOS, macOS, and iPadOS. The rollout since then has been more complicated.
What is demonstrably live as of iOS 18.4 and macOS Sequoia 15.4: Writing Tools (rewrite, proofread, summarize) work across Mail, Notes, Pages, and most third-party apps via the Share menu. Priority notifications in Mail sort messages using on-device classification. The Genmoji feature generates custom emoji from text prompts. Photo cleanup — the inpainting tool that removes objects from images — shipped in iOS 18.2 and works reliably on iPhone 15 Pro and newer. Siri's expanded vocabulary and screen-context awareness shipped in 18.2 as well, though performance has been uneven.
What has been delayed or scaled back: The ChatGPT integration inside Siri — announced as a flagship feature — arrived in iOS 18.2 but requires an opt-in confirmation on every use and cannot access private data like contacts or calendar. Apple's promised ability for Siri to take actions inside third-party apps has shipped only for a small set of Apple's own apps; the App Intents framework for third-party developers is live, but meaningful adoption is still sparse. On-device model capabilities are limited to Apple Silicon devices — iPhone 15 Pro, M-series Macs, and M4 iPads.
In Europe, Apple Intelligence features are still unavailable on iPhone and iPad as of July 2026. Apple cited regulatory uncertainty under the Digital Markets Act. The company told the Wall Street Journal it expects to begin a phased European rollout in Q3 2026, but has not committed to a specific date.
The deeper issue is architectural. Apple's Private Cloud Compute — the infrastructure that handles queries too large for on-device processing — is technically impressive, but developers have no programmatic access to it. That limits what third-party apps can build on Apple Intelligence, compared to what they can build on OpenAI's API or Google's Gemini API with full direct access.
Apple Intelligence is real and improving. It is also narrower, slower to ship, and more geographically fragmented than the WWDC announcement implied.
