What does mean personal AI in that concept?
AI - the ability of technological systems to perform self-learning, decision-making, and self-correction processes.
AI can learn your habits. It may decide what content to show you, when the best time to disturb you and can make an appointment, answer the call, etc. It can be understood that you always go to a cafe more often in the afternoon, you like to visit the sea once a month and how much time you spend on a photo or a post with text during scrolling. Self-correction can occur this way if you stop going to the sea once a month and start practising in the pool. To understand these features in more detail, I will give examples.
Personal AI is nothing more than the functionality of existing devices capable of collecting and processing data in our personal space to make decisions for improving our life.
For example, based on your search queries and frequent search for podcasts, the AI can decide to show you a search query in voice control format. For another person, the search result may be a story described in a fiction style that can influence the course of events.
