Apple Adds Grammar Checker, Shortcuts, Wallpapers in iOS 27

Bloomberg reports that Apple is preparing expanded Apple Intelligence features for iOS 27 and iPadOS 27, including an AI grammar checker, natural-language Shortcut creation, and AI-generated wallpapers (Bloomberg, May 18, 2026). MacRumors and iDropnews additionally report system-level integration across iOS 27, iPadOS 27, and macOS 27 and note UI details such as a Write With Siri toggle and a Help Me Write option when a text field is active (MacRumors; iDropnews). Multiple outlets connect the leak to Bloomberg's Mark Gurman and place the public unveiling at Apple's WWDC keynote on June 8, 2026 (MacRumors; AppleInsider; Macworld).

Reporting by Mark Gurman, as carried by Bloomberg and excerpted in outlets including iDropnews and MacRumors, describes the new grammar checker operating from a translucent menu that slides up from the bottom of the screen and shows original text alongside suggested revisions (Bloomberg; iDropnews; MacRumors). MacRumors says users will be able to accept or reject suggestions individually or apply all changes at once, and that the tool will add grammar suggestions on top of existing spellchecking (MacRumors). Macworld and AppleInsider also report an Image Playground or wallpaper-generation feature and expanded Shortcut creation that accepts natural-language prompts to build system-wide automations (Macworld; AppleInsider).

Editorial analysis: Companies integrating system-level writing assistance typically increase baseline productivity for a broad user base while shifting demand away from third-party editors. Integrated grammar tools that display suggested edits inline reduce the friction of comparing rewrites, which in other ecosystems has led to broader adoption of built-in composition aids rather than standalone browser extensions or apps. For platform engineers and product teams, delivering an interface that supports selective accept/reject workflows is a common UX requirement for adoption of automated rewriting features.

Editorial analysis: The reported UI details, a bottom-sheet menu showing original versus revised text and granular accept/reject controls, mirror design patterns used by dedicated grammar tools and by generative-text assist features in other mobile platforms. From an engineering perspective, implementing selective edits at the system level typically requires consistent text-handling APIs across apps and careful composition of delta edits so host apps can preserve formatting and metadata. Macworld also reports Apple is developing an entirely new language model to power Apple Intelligence; that claim is reported by Macworld and should be treated as a sourced report rather than an established technical fact (Macworld).

For practitioners: Observers should track whether Apple executes these features on-device or via cloud inference, because the deployment model affects latency, privacy tradeoffs, and developer integration points. Also watch for API changes to the Shortcuts or text-input systems that enable natural-language shortcut creation, since those will determine how third-party apps can opt in or expose actions. Finally, monitor official communications from Apple at WWDC on June 8, 2026; as of these reports Apple has not published a public statement detailing the leaks covered by Bloomberg and other outlets (Bloomberg; MacRumors; AppleInsider).
