iOS 27 adds new features for CarPlay, Messages, and Apple Notes, including divider lines for organizing notes. To insert one, tap where you want the line, open the edit menu, and choose 'Insert Divider Line'. Section links are now supported, letting you build a table of contents for longer notes.

Select text, open the edit menu, choose 'Add Link', then 'Link to Section' to create a direct link to any heading or subheading in your note. The biggest upgrade is Siri AI integration: you can now use Siri to quickly add information to a new or existing note, reformat lists, or pull answers directly from the Siri app. Markdown support is enhanced—pasting Markdown-formatted text now auto-converts to rich text, and a new 'Copy as Markdown' option lets you export notes as Markdown with zero extra steps.

Image Playground upgrades also benefit Notes users, offering photorealistic image generation via Private Cloud Compute with hidden Synth ID watermarks. Additional UI refinements include a refreshed app icon, Liquid Glass updates for buttons and menus, and updated icons for shared folders and notes.
