Apple's genai.apple.com subdomain signals major Siri overhaul ahead of WWDC 2026

Apple quietly stood up genai.apple.com, a new subdomain widely read as the marketing home for an overhauled Siri and expanded Apple Intelligence feature set at WWDC 2026 in June. Reporting suggests Siri will become substantially more conversational and context-aware, with a dedicated Siri app (currently it lives only as a system service), automatic chat deletion options for privacy, and deeper hooks into Mail, Messages, Calendar, and Notes.

The biggest architectural piece is the previously rumored Google partnership: Apple will reportedly use custom Gemini AI models, fine-tuned by Google for Apple's privacy and on-device constraints, as the heavy-lift engine behind the new Siri. This is the deal Aravind Srinivas alluded to with his 'iPhone ~= MacBook, thanks to server side agents' tweet — Apple is betting on cloud agents (via Gemini) rather than trying to win the foundation-model race on-device.

Competitively, this concedes the model-quality war and bets on integration: only Apple can ship Siri-on-Lock-Screen with cross-app intent. The price is dependence on a strategic rival — Google now powers the assistant on its largest competitor's platform, and the revenue-share terms will likely surface in Google's next 10-Q.

The skeptical takes from r/apple and HN: Siri has been 'about to get good' for a decade, and adding a chat-deletion toggle won't fix the fundamental UX rot. The real test at WWDC is whether the new Siri can complete the kind of multi-step task that ChatGPT and Gemini Spark already handle — book a flight, draft a reply with context from yesterday's email, find a photo by description. Anything less and it's a marketing refresh, not a Siri overhaul.
