> The Research Partner for Modern Scientists.

Nujan (nu·jan /ˈnuː.dʒən/) is an active academic research partner designed for researchers, scientists, PhD students, and machine learning engineers. Unlike passive PDF summarizers, Nujan provides pedagogical Socratic roadmaps, adversarial AI peer-review sparring, an integrated in-app PDF reader with KaTeX math rendering, and multi-source conference and paper discovery.
