Top 10 NLG Software in 2021

Top Natural Language Generation (NLG) Software in 2021

Natural Language Generation is a fast-growing sub-field of Artificial Intelligence. No wonder since the need for written and audio content is ever-increasing in many businesses and human-made texts are expensive and take long in production. NLG software optimizes that process and therefor saves time and costs by analyzing structured data and translating them to text.

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

Natural language generation software can convert data into language and therefore create written and spoken text. Therefore, its importance for many types of business cannot be neglected. It can automatically generate informative content such as reports and summaries without needing a human for the time-consuming tasks of analyzing data and writing the content.

The use of NLG technologies especially makes sense for companies that work with a lot of structured data as the basis of their content. They typically belong to industries such as e-commerce, finance and banking, pharma, insurance, or media and publishing. Natural language generation can, however, be beneficial for a wide variety of businesses that do not belong to one of the industries mentioned.
