About Primer

Primer is pushing the edge of artificial intelligence. We are building machines that can read natural language text documents, understand them, and share what they learn by writing their own natural language text documents. Join us!

At Primer we use machine learning and natural language processing to automate the analysis of very large corpuses of unstructured text. We build systems that read documents, extract insights, and write reports comparable to those of a human analyst. Our objective is to help our customers understand the world around them ‐‐ from geopolitical events and scientific research to changes in the risk profiles of companies. Our clients include some of the world’s largest corporations, financial institutions, and government agencies.

You can learn more about Primer's technology and the sort of problems we solve at our blog, as well as recent media coverage of our work. Primer was chosen by the World Economic Forum among a select group of Technology Pioneers.
