TechCrunch has been putting the developer beta of iOS 18.1 through its paces as part of our iPhone 16 Pro Max review. There are a handful of standout features, including cross-system writing tools, Clean Up for Photos, and the biggest revamp to Siri since launch.

Writing Tools takes advantage of the kinds of generative AI features familiar to anyone who has played around with ChatGPT and its ilk. Along with proofreading and summarizing, the system will rewrite text in a variety of styles, including professional, concise, and friendly. Over in Mail, users gain a Smart Reply feature, message prioritization, and summaries.
