iOS 27 is shaping up to be one of the most feature-rich updates in recent years, with a new report from Bloomberg detailing three significant additions: AI-generated custom wallpapers, a revamped Shortcuts app that understands natural language, and improved Writing Tools that include a powerful grammar checker. The report, which cites sources familiar with the software’s development, suggests Apple is doubling down on artificial intelligence to make everyday tasks more intuitive and personalized.
The headline feature is a new wallpaper customization option that leverages Apple's existing Image Playground app. According to the report, the wallpaper picker will include a dedicated option for creating custom lock screen and home screen backgrounds using AI. Users will be able to describe the type of wallpaper they want—such as a serene beach scene, abstract geometric patterns, or a vibrant gradient—and the system will generate a unique image tailored to their request. This builds on the limited wallpaper customization introduced in iOS 16, which allowed users to add widgets and change fonts but stopped short of full AI generation. The new feature is expected to debut alongside a redesigned wallpaper picker interface that makes it easy to browse, preview, and apply AI-generated designs. For power users, the ability to generate multiple variants and save them for later use could revolutionize how they personalize their devices.
Beyond wallpapers, the report highlights major improvements coming to the Shortcuts app. Currently, creating automations requires a degree of technical understanding, as users must string together actions from a list of pre-defined steps. iOS 27 aims to eliminate this barrier by allowing users to describe their desired shortcut in plain English. For example, a user could type or speak, "Every weekday at 7 AM, turn on Do Not Disturb, send a message to my partner saying I'm on my way to work, and open the calendar," and the system would automatically build and install the shortcut. This marks a significant leap forward in accessibility, potentially bringing automation to millions of iPhone users who previously found Shortcuts intimidating. The new interface presents a prompt asking, "What do you want your shortcut to do?" followed by a text field. Once the user submits their request, the AI analyzes the intent, maps it to available actions, and creates a fully functional shortcut. The report notes that the system can handle complex conditionals and loops, though simpler requests will likely be the most reliable at launch.
Apple is also updating its Writing Tools suite, first introduced in iOS 18, to include a grammar checker that rivals third-party services like Grammarly. The feature appears as a translucent menu that slides up from the bottom of the screen, displaying original text alongside suggested revisions. Users can accept individual suggestions, approve all changes, or ignore them entirely. Additionally, there are controls to pause grammar checking and navigate between flagged sections of text, making it easier to review long documents. The system reportedly uses a combination of on-device machine learning and server-side processing to catch grammatical errors, tone issues, and stylistic improvements. To make Writing Tools more discoverable, Apple is testing a "Write With Siri" toggle that appears at the top of the keyboard, as well as a "Help Me Write" button that appears when users activate Siri while working in a text field. These additions align with Apple’s broader push to integrate AI into every aspect of the iPhone experience, much like Google’s Pixel lineup and Microsoft’s Copilot.
The timing of these features is no coincidence. Apple is expected to announce iOS 27 at its Worldwide Developers Conference in just three weeks, with a public release likely in September alongside the iPhone 18 series. The company has been under pressure to demonstrate its AI capabilities, especially after competitors like OpenAI, Google, and Microsoft have released generative tools that are now deeply integrated into productivity suites and mobile operating systems. By embedding AI into core system apps like Wallpaper, Shortcuts, and Writing Tools, Apple is betting that useful, privacy-focused features will resonate with its user base more than standalone chatbots or image generators.
From a historical perspective, Apple has slowly but steadily increased the role of machine learning in iOS. The Neural Engine in its custom A-series chips has enabled on-device processing for years, powering features like Live Text, Visual Look Up, and subject removal from photos. iOS 27 represents a shift from incremental improvements to transformative changes, where AI becomes the primary driver of interactivity. For instance, the grammar checker in Writing Tools could eventually evolve into a full writing assistant that not only corrects errors but also suggests alternative phrasings, adjusts tone, and even generates longer content. Similarly, the natural language Shortcuts feature could pave the way for a more conversational Siri that can execute multi-step commands without requiring users to pre-configure anything.
Privacy remains a key concern for Apple, and the report indicates that most of the AI processing for these features will happen on-device. The grammar checker, for instance, uses a local model that learns from the user's writing style without sending data to the cloud. The wallpaper generator will also run on-device via the Image Playground app, which already uses a similar architecture for creating stickers and images. However, some tasks, like complex shortcuts that integrate with third-party services, may require cloud processing for authentication and server-side logic. Apple has not yet commented on the specifics of its privacy architecture for iOS 27, but the company is expected to emphasize its commitment to end-to-end encryption and on-device intelligence during the keynote.
Beyond these three features, the report alludes to other improvements, such as a revamped Health app with AI-driven coaching, a smarter Photos app that can create narratives from your gallery, and a new Siri API for developers. While details are scarce, the three confirmed features already suggest that iOS 27 will be a milestone release that redefines how users interact with their iPhones. For power users, the Shortcuts upgrade alone could save hours of manual configuration. For casual users, the AI wallpaper generator offers a fun, creative outlet that was previously only possible with third-party apps. And for writers, students, and professionals, the grammar checker provides a seamless way to polish their writing without leaving Apple’s ecosystem.
The report concludes by noting that all these features are still in the testing phase and could change before the final release. Apple often adjusts new additions based on internal testing and developer feedback during the beta period. Still, the direction is clear: Apple is fully embracing AI to enhance personalization, automation, and productivity. With the WWDC keynote just weeks away, anticipation is building for what could be the most ambitious iOS update in years. Whether these features will be enough to sway users who have been impressed by rival AI offerings remains to be seen, but for longtime iPhone owners, iOS 27 promises to bring a level of intelligence and customization that was previously unimaginable.
