Apple says Writing Tools are built into iOS 18, iPadOS 18 and macOS Sequoia

Apple introduced Apple Intelligence at its annual WWDC keynote.[1] Apple says the tools are built into iOS 18, iPadOS 18 and macOS Sequoia.[2] Their core functions are rewriting, proofreading and summarizing text.[2] The announcement positions them as writing assistance within Apple's operating systems, rather than as a single-purpose feature for one app. Apple says the tools are intended to help users feel more confident in their writing.[2]

Rewrite generates alternate versions of text a user has already written, and Apple says users can choose one that better fits their style or tone.[1] Apple says it can make text friendlier, more professional or more concise.[3] Proofread can identify misspellings and grammar errors.[3] Summarization can turn text into key points, while the tools can also convert text into lists or tables.[3] CNBC additionally reported that Writing Tools can draft Smart Replies to messages.[4]

Suggestions appear inline so users can review and integrate changes, and Apple says they can consider suggestions one at a time.[3] That workflow gives users an opportunity to inspect proposed edits rather than simply receive a rewritten result. In the WWDC preview, Rewrite appeared as a small blue button after text was selected.[1] For text that is not editable, Writing Tools displays results in a separate panel; users can copy or share those results.[3]

Apple says Writing Tools will be available systemwide nearly everywhere users write, including Mail, Notes and third-party apps.[1] Apple also lists Pages alongside Mail, Notes and third-party apps as places where the tools can be used.[2] CNBC reported that the features can change the tone of existing copy and summarize messages in a “TLDR” format.[4]
