A branch of artificial intelligence focused on enabling computers to understand, interpret, and generate human language. NLP underpins the ability of AI agents to read documents, understand user requests, extract information from text, generate responses, and engage in natural conversations — making it the foundational technology behind modern conversational AI and agentic systems.

LLM (Large Language Model)
A deep learning model trained on massive amounts of text data that can understand and generate human-like language. LLMs like Claude, GPT, and Gemini serve as the reasoning engine behind AI agents, enabling them to understand instructions, process information, and generate intelligent responses.
AI Agent
An autonomous software system powered by a large language model (LLM) that can perceive its environment, make decisions, and take actions to achieve specific goals. Unlike simple chatbots, AI agents can use tools, access external data, maintain context across interactions, and chain multiple reasoning steps together.
