Apple tests major Siri AI upgrade in iOS 27 beta 4 with hidden macOS features

Apple's iOS 27 beta 4 surfaced its most substantial Siri overhaul yet: a new visual experience tied to the Dynamic Island, a dedicated Siri app that lets users revisit past conversations, and expanded Visual Intelligence including a Siri mode inside the Camera app. Separately, developers digging through the macOS 27 public beta found a hidden Siri interface plus contextual text-editing tools — rewrite, proofread, and summarize — surfacing as pop-ups, though disabled by default. Apple also opened a Siri AI beta waitlist so users can try the revamped assistant.

The mechanism reflects Apple's pattern of staging AI features behind betas and waitlists rather than a splashy launch, extending Apple Intelligence deeper across iPhone, iPad, and Mac. The Camera-integrated Visual Intelligence and Dynamic Island surfacing aim to make Siri feel more proactive and multimodal, closing distance to Gemini Live and ChatGPT's visual features.

Competitively, Apple remains behind on conversational AI, and the drip of hidden features signals it is still finishing a Siri that has slipped repeatedly. The context this week is instructive: Google touted Gemini rolling out to Samsung foldables with task automation across 40+ apps, exactly the kind of agentic capability Apple's Siri still lacks. On the hardware side, the iPhone 18 Pro entered mass production. Skeptics note betas often hide features that ship late or not at all. Watch whether the Siri app and Visual Intelligence make the public iOS 27 release and how the assistant compares to Gemini and ChatGPT once live.
