NLG (Natural Language Generation) companies develop NLG software which helps companies auto-generate articles and reports. Most common use cases include:

  • Automated article generation speeding up content creation of media companies, helping them build long tail, timely content
  • Automated reports (e.g. financial reports) which enable executives to get to the facts without spending time with complex reporting software

To be categorized as an NLG company, a company's product must be capable of automatically producing text based on a variety of input including tables or other text

How relevant, verifiable metrics drive AIMultiple’s rankings

AIMultiple uses relevant & verifiable metrics to evaluate vendors.

Metrics are selected based on typical enterprise procurement processes ensuring that market leaders, fast-growing challengers, feature-complete solutions and cost-effective solutions are ranked highly so they can be shortlisted.
Data regarding these metrics are collected from public sources as outlined in the “What are AIMultiple’s data sources?” section of this page.


There are 2 ways in which vendor metrics are processed to help prioritization:
1- Vendors are grouped within 4 metrics (customer satisfaction, market presence, growth and features) according to their performance in that metric.
2- Vendors that perform high in these metrics are ranked higher in the list.


The data used in each vendor’s ranking can be accessed by expanding the vendor’s row in the below list.
This page includes links to AIMultiple’s sponsors. Sponsored links are included in “Visit Website” buttons and ranked at the top of the list when results are sorted by “Sponsored”. Sponsors have no say over the ranking which is based on market data. Organic ranking can be seen by sorting by “AIMultiple” or other sorting approaches. For more on how AIMultiple works, please see the ethical standards that we follow and how we fund our research.

Which NLG solution provides the most customer satisfaction?

AIMultiple uses product and service reviews from multiple review platforms in determining customer satisfaction.

While deciding a product's level of customer satisfaction, AIMultiple takes into account its number of reviews, how reviewers rate it and the recency of reviews.

  • Number of reviews is important because it is easier to get a small number of high ratings than a high number of them.
  • Recency is important as products are always evolving.
  • Reviews older than 5 years are not taken into consideration
  • older than 12 months have reduced impact in average ratings in line with their date of publishing.

Learn more about NLG Software

Natural Language Generation (NLG) includes techniques for translating information into text. NLG is a subset of Natural Language Processing (NLP). If natural language processing techniques can be separated into two, Natural Language Understanding (NLU) is the part that analyzes natural language, NLG is the part that synthesizes meaningful text for human consumption. NLP=NLU+NLG. For example, let's imagine that you are writing to a conversational AI solution. When you ask what the weather is like today, NLU techniques are used first to understand your intent. Weather data is then searched, the results are analyzed and an answer generated thanks to NLG techniques.

NLG techniques can be used to automatically summarize and explain data in a human-like manner. NLG can automate the transfer process of analyzed structured data to humans in seconds.

NLG saves time and costs as well as contributes to scalability and consistency via automating repetitive processes involving language.  

  • Time and cost savings: NLG reduces time and costs as it speeds up the reporting processes.
  • Reporting consistency: Reports can be precise and standardized as though they are created by one person. Accuracy of the reports can be improved by time as NLG solutions advance.
  • Scalability: By automating parts of the reporting and content generation processes, it becomes possible to create large amounts of content.

Important factors in evaluating an NLG solution are: evaluating use cases, the existence of suitable data sources, security, language capabilities and vendor dependency.

  • While evaluating NLG solutions, it is necessary to find vendors that provide solutions for a particular use case. For example, an NLG solution trained to prepare content in the field of e-commerce would not be suitable for reporting the efficiency of IoT devices.
  • NLG solutions can be as good as the underlying data. The project team needs to ensure that they have the structured data which can be combined with the NLG solution to serve users.
  • The audience of the reports or content is important. Publishing public content is always risky and would require a more robust quality assurance process.
  • In situations where language skills are important, a robust assessment of the NLG tools' language capabilities is necessary. For example, correct use of language is far more important in media and journalism compared to a company's internal reporting.
  • Large-scale enterprises can build their own NLG engines using open source solutions and minimize vendor dependency. Two aspects are important in this decision: 1) Is the use case highly specialized? If yes, it may be harder to find an NLG solution from a vendor for that case. 2)Is this a simple or difficult NLG problem? Simple problems can be easily resolved with open source packages.
