Natural Language Generation is a subset of NLP focused on producing human-like text from structured inputs — such as data tables, databases, templates, or rules. NLG is used in automated report generation, sports score summaries, financial briefings, and product description creation. In marketing, NLG enables the automatic generation of personalized email content, ad copy variations, and data-driven narrative summaries at scale. Advanced LLMs have blurred the line between NLG and general text generation.
