Why ask this instead of just looking it up? You could even have explained it after doing so and helped other people who don’t know.

Quote from an article explaining it:

Intent-based UI is a design philosophy that aims to bridge the gap between user expectations and system capabilities. It involves designing interfaces that can understand and predict user intentions, enabling the system to respond proactively and provide relevant information or actions. This approach not only enhances user satisfaction but also fosters a more efficient and productive interaction with the system.
