From Basic Proofreading to a Full AI Grammar Checker
Apple is preparing a major upgrade to its native text tools with iOS 27, bringing an advanced AI grammar checker directly into the operating system. Where current iOS features offer only lightweight summaries and simple proofreading, the new system is designed to rival established services like Grammarly. When a user highlights text, a translucent panel will slide up from the bottom of the screen, displaying a side‑by‑side comparison between the original passage and suggested improvements. These recommendations go beyond typos, tackling structure and tone as well. Users can accept edits one by one, apply all of them in a single tap, or dismiss the suggestions entirely. By embedding these capabilities at system level rather than relying on browser extensions or standalone apps, Apple is clearly positioning its iOS 27 writing tools as the default AI grammar checker for everyday typing on iPhone and iPad.
Siri Writing Assistant: ‘Write With Siri’ and ‘Help Me Write’
The most visible change for users will be the evolution of Siri into a true writing assistant. A new “Write With Siri” toggle will appear above the digital keyboard, allowing users to generate emails, messages, or longer texts without leaving the app they are using. Activating Siri while typing will also surface a “Help Me Write” prompt, turning the assistant into an on‑demand editor that can rewrite awkward sentences or offer alternatives. According to reports, the next version of Siri will behave more like a conversational AI chatbot, mixing text and audio responses, handling follow‑up questions, and even parsing multiple requests in a single command. Combined with iOS 27 writing tools, Siri shifts from being a simple voice control layer to becoming a context‑aware AI grammar checker and drafting partner designed to work wherever text fields appear across the system.
Automated Shortcuts and AI Wallpapers Keep Users Inside iOS
Beyond writing, Apple is infusing more of iOS 27 with AI to reduce friction and keep users within its own apps. Shortcuts, long considered powerful but intimidating, will gain a natural language layer so people can describe a desired workflow instead of manually chaining actions together. This echoes Google’s recent push to let Android users build widgets from simple prompts, but Apple’s approach ties directly into system automation. At the same time, the wallpaper picker will tie into Apple’s Image Playground engine, enabling on‑device generation of custom backgrounds from text ideas. While third‑party apps already offer AI wallpapers and automation tools, native support means users can personalize their devices without hunting for extra downloads. Together, these Apple AI features suggest a strategy: make the OS smart enough that most people never feel the need to look elsewhere for creativity or productivity tools.
Challenging Grammarly and Closing the AI Gap with Rivals
The new Siri writing assistant and grammar tools arrive as Apple faces pressure from AI‑centric competitors. Google and Samsung have aggressively marketed on‑device and cloud‑based assistants that summarize, rewrite, and manage workflows, and Google has already announced AI‑generated widgets for Android. Apple, often seen as trailing in AI despite initiatives like Apple Intelligence and its integration with ChatGPT, is now reportedly tapping Google Gemini as an underlying model to power a more capable Siri experience. At the same time, Apple is exploring a flexible model‑choice layer, potentially turning iOS into a marketplace for AI providers. Within that context, a built‑in Grammarly‑style editor is both defensive and offensive: it protects Apple’s platform from third‑party lock‑in while offering a tangible, everyday benefit. If executed well, iOS 27’s writing tools could transform Siri from a novelty into a compelling reason to stay within Apple’s ecosystem.
Privacy, Control, and the Future of On-Device Editing
Apple’s long‑standing emphasis on privacy gives its AI writing ambitions a distinctive angle. Reports suggest users will be able to control how long Siri retains conversation history, including a limited‑memory mode aimed at privacy‑conscious users. That matters when your assistant is reading, correcting, and sometimes drafting sensitive documents and messages. For professionals who currently rely on cloud‑based writing tools, an OS‑level AI grammar checker that keeps more data on device could be attractive. However, success will depend on the balance between power and control. Apple and app developers may still restrict which actions AI‑generated shortcuts can trigger, limiting full automation. Likewise, writers will judge Siri’s suggestions not just on correctness but on style, clarity, and cultural nuance. If Apple can combine strong privacy defaults with genuinely useful, flexible editing, iOS 27 may mark the moment when AI‑assisted writing becomes a standard expectation across its platform.
