Top 10 NLG Software in 2022

Top Natural Language Generation (NLG) Software in 2022

Natural Language Generation (NLG), the automated content generation, is a fast-growing subfield of artificial intelligence. This is no surprise, as the demand for written and audio content is steadily increasing, and human-generated content can be costly and time consuming to produce. The NLG software optimizes this process and saves time and money by analyzing structured data and translating it into text, like product descriptions.

What is NLG software, how does it work and where can it be used?

A Natural language generation software can transform information into language and hence produce written and spoken content.

Its importance to many types of businesses, therefore, should not to be ignored. It can automatically generate informative content, such as reports and summaries, with no need for a human to perform the time-consuming tasks of analyzing data and writing the content. 

Using NLG technologies is most useful for companies that use structured data as the basis for their content.

These are typically used in e-commerce, finance and banking, pharmaceutical, insurance, or media and publishing industries. Natural language content generation, however, can benefit a wide range of companies outside of these industries, as well.
