An AI app is a mobile application that utilizes artificial intelligence technologies, computer vision, natural language processing, and machine learning to perform human-like tasks.

• Replying to a voice or text command naturally and having skills in conversation
• Automating tasks like scheduling emails and reminders
• Creating text, image, or music content
• Customizing user experiences based on their habits and preferences
• Providing real-time support for education, health, and productivity
