I demoed Samsung's new Galaxy AI features - these 3 made my iPhone look bad

As implied by the inclusion of "personal" in the title, this is the most similar feature to the overarching principle of Apple Intelligence. Samsung's Personal Data Engine functions as a personal LLM that learns from you with your everyday device usage, ultimately creating an assistant that can anticipate your needs using the context of your phone activity.

Essentially, the Personal Data Engine learns what you do and what you want to do to provide you with all day support that predicts what you are about to do and display helpful insights. 

Of course, data concerns naturally arise from such an application, which Samsung addressed heavily upon launch. For starters, the experience can be turned on or off with a menu toggle. Even if you turn the feature on initially, if you change your mind and turn it off, all of your data is erased. 

When the toggle is on, the data is stored on the device, and not on the cloud, giving users the reassurance that their personal data will remain more heavily protected. However, the tradeoff of the extra security is that if you lose the device, your data is lost forever. 

Using this information, it can provide tailored experiences for you such as Now Brief, a feature that gives you suggestions accessible via your Now Bar on the lock screen. Intended to anticipate your needs based on your routines and habits, it may suggest driving mode or display directions to a specific destination.

Personal Data Engine will also provide morning and evening briefs, which each offer different relevant information depending on the time of day. Your morning brief may include summary of your sleep, weather forecasts for the day and schedule reminders. Your evening brief may include a summary of your day's events and photos you took. Either way, it is a helpful tool to give you the information you need without you having to look for it -- saving you time.
