Short answer
Natural language processing (NLP) is the field of AI that lets machines read, interpret, and generate human language, turning unstructured text and speech into something software can act on.NLP covers a wide span of tasks: tokenizing text, parsing grammar, recognizing entities, detecting sentiment, classifying meaning, and producing fluent responses. Modern NLP is dominated by large language models, but the discipline predates them and still includes lighter, task-specific models that are faster and easier to govern.
In customer experience, NLP is the substrate under every AI feature: it is how an incoming message gets understood before anything is decided. The interesting question is not whether a vendor uses NLP. Everyone does. The question is what the NLP is pointed at.
Aide, the AI platform for customer service, points NLP at intent first. Rather than treating every message as a generation problem to be answered, Aide uses NLP to classify the customer's intent against a structured Customer Intent Map, then decides what can be automated. Understanding precedes action.
That output is confidence-scored, and no automation goes live without being tested against real past conversations first. The intents the models surface stay visible to the team, so people understand the system they operate.
