Natural Language Processing (NLP) is AI's ability to understand human speech as it is spoken. Traditional apps require strictly formatted inputs. NLP understands context.
When you tell a financial apps tracker with voice something like 'I just dropped fifty bucks at the gas station', NLP translates 'dropped' to 'spent', 'fifty bucks' to '$50', and 'gas station' to the 'Transport/Fuel' category.
