iOS 27 beta 3 lets Siri AI pull info from third-party apps

Apple's long-promised Siri overhaul is taking shape in the iOS 27 developer beta. Beta 3 lets Siri AI pull information from third-party apps — the App Intents-style contextual awareness Apple pitched at WWDC26 — and adds 'Pace' and 'Expressivity' controls so users can tune how fast and how expressively Siri speaks. These are foundational pieces of the Apple Intelligence rollout slated for fall 2026.
Apple also extended Siri AI to the Apple Watch via watchOS 27 beta 3, adding a dedicated Siri app in the Dynamic App Grid that handles complex queries and completes tasks on-wrist. Crucially, the Watch offloads processing to a nearby Apple Intelligence-compatible iPhone rather than running models locally, and conversations sync across the user's Apple devices — a pragmatic architecture given the Watch's power and thermal limits.
The competitive reality is unflattering. Reviewers found Google's Gemini Pro models outperform Siri AI on in-depth research tasks, and Apple remains a year or more behind frontier assistants in raw capability. Apple's bet is that deep OS integration, on-device privacy and cross-app context beat raw model horsepower for everyday use — a thesis it has yet to prove at scale.
The caveat is that these are beta features that have slipped before; Apple's Siri revamp has a history of delays, and 'arriving fall 2026' has room to move. Watch whether third-party app support ships broadly at launch or arrives gated to a handful of partners, and whether Apple's privacy-first, iPhone-tethered approach feels capable or constrained once real users try it.
