Systemwide dictation improvements include automatic punctuation insertion, capitalization, and formatting. Custom voice selection allows users to adjust pace and expressiveness, though this specific feature requires M3 chips or newer hardware with at least 12 gigabytes of unified memory.

What changes define the Safari and productivity suite?

Safari receives several Apple Intelligence-driven enhancements designed to streamline web navigation and content management. Automatic tab organization groups related browser windows into thematic collections. The system continuously monitors browsing activity and restructures tabs as users research different topics. This functionality reduces visual clutter and maintains project continuity without manual folder management. The feature operates silently in the background, adapting to user habits over time.

The Notify Me capability introduces proactive web monitoring. Users can instruct the browser to track specific pages for price reductions, inventory restocks, or content updates. The system delivers targeted notifications when monitored conditions change, eliminating the need for manual refresh cycles. This functionality proves particularly useful for e-commerce tracking and time-sensitive information gathering. The browser effectively transitions from a passive viewing tool to an active monitoring agent.
