Apple's iOS 27 brings Grammarly-like AI writing to Siri at WWDC

Apple is gearing up for a major Siri overhaul at WWDC 2026, according to Bloomberg's Mark Gurman. The centerpiece is a Grammarly-like writing tool that will display suggested revisions at the bottom of the screen, allowing users to accept individual changes, accept all, or reject all. This sits alongside "Write With Siri," a keyboard-based generator for emails, texts, and essays. Together, these features aim to bring Apple's AI capabilities closer to what Google and Samsung offer, while maintaining Apple's privacy-first approach. Users will also be able to create AI-generated shortcuts by describing what they want—a significant expansion of the Shortcuts tool that previously required developer approval for custom automations. This mirrors Google's recent Android 17 feature that lets users create widgets via prompts. Additionally, Apple will natively support AI-generated wallpapers for lock and home screens.

Under the hood, Apple is partnering with Google to integrate Gemini as the underlying model for Siri, paying an estimated $1 billion per year. The new Siri will behave more like an AI chatbot, supporting text alongside audio, better contextual awareness, and the ability to stack multiple requests into a single command. Apple is also exploring a flexible model marketplace where users can choose their preferred AI model—potentially creating a revenue stream similar to search engine defaults. To differentiate on privacy, iOS 27 will let users set how long Siri retains conversations, with a limited-memory option. These updates follow Apple's reported focus on cleaning up iOS and improving performance, but the AI push signals a renewed effort to catch up after falling behind in the generative AI race.
