Apple seeded iOS 27 and iPadOS 27 Beta 2 to developers today, and one of the most significant changes is a keyboard-level promotion for Write with Siri. The feature no longer lives in a long-press text selection menu; it is now a persistent suggestion on the iPhone and iPad software keyboard, replacing the older Writing Tools button entirely.
Writing Tools, which debuted as part of Apple Intelligence in iOS 18, required you to first select text and then navigate a context menu to reach it. In Beta 2, Write with Siri surfaces before you have typed a single word, appearing as a prompt above the keyboard when a text field is empty. Once you start typing and highlight text, that same Siri button appears in line, bringing it much closer to the original Writing Tools interaction for editing selected passages. If you want a broader look at what else Siri AI brings to iOS 27, the iOS 27 accessibility and AI features arriving alongside it are worth reviewing.
What Write with Siri can do
The feature is systemwide, meaning it works in any app that uses the standard iOS keyboard, not just Apple’s own. Siri AI can match your writing style, punctuation, and tone in Messages and Mail so that composed text sounds like you rather than a generic AI output. The full capability set covers four distinct functions:
- Generate text from scratch in any app, including full document drafts
- Give feedback on selected text, for example assessing how a passage sounds or reads
- Proofread automatically as you type, catching spelling errors and grammar issues
- Edit at your direction, such as rewriting a paragraph in a more professional tone
Apple’s foundation models for Siri AI in iOS 27 were developed using technologies from Google’s Gemini AI models. The style-matching capability in Mail and Messages draws on that collaboration to personalise output within those two apps specifically.
Write with Siri is part of Siri AI and therefore part of Apple Intelligence, which requires an iPhone 15 Pro or later. Before installing, it is worth checking the iOS 27 developer beta device risk checklist to see whether your hardware is a good candidate. The base iOS 27 release supports iPhone 11 and later, so a large portion of the installed base will get the new OS but not the AI writing features. Advanced capabilities including customisable voice, pace, and expressivity controls are limited further, requiring an iPhone 17 Pro or iPhone Air.
Other Beta 2 changes
Beta 2 ships two weeks after the first beta arrived alongside the WWDC 2026 keynote on June 8, and the build already feels further along than most developer betas at this stage. Other changes in this iOS release include:
- RCS in Messages now supports inline replies
- iPhone Mirroring stability has been improved
- A firmware update fix for AirPods Max 2 is included
- An Apple Home update for remote Apple TV 4K control
- Siri Expressive Voice controls for Pace and Expressivity are listed as “coming soon”
Early testers have also noted that Siri AI response speed feels faster in Beta 2 than it did in the first build, which aligns with Apple’s stated emphasis on stability and performance as core iOS 27 qualities.
