Polyplexus is composed of three integrated components: a public information feed where users can promote interesting research and connect it to other research via tweet-like summary statements called micropubs; a private tool for synthesizing new ideas, known as micropub portfolios; and an incubator environment. Incubators allow research sponsors in government and industry to post specific topics of interest and find research and development specialists to address their challenges.

Following a 2018 test phase that was restricted to academic researchers, Version 1 of Polyplexus is now open to the public. Researchers and research sponsors across disciplines and industries are invited to sign up and become "Plexors" here.

Anyone may create an account and contribute to the public areas of the site. Retired scientists, engineers, and researchers are especially encouraged to continue to share their expertise by engaging as Plexors. Plexors can also contribute suggestions for new features that will be included in Polyplexus Versions 2 and 3, which are planned for development over the next 18 months.
