NNScholar

NNScholar is an academic research workspace that combines literature discovery, paper reading, evidence organization, and writing workflows. The site says users can begin a review from a topic, DOI, PMID, arXiv identifier, or research question, then save sources to a research project. It includes PDF chat, translation, annotation, and question answering in the context of a paper, plus a library for notes, files, conversations, and project stages. Its AI research agents and evidence board are intended to connect claims with sources, decisions, and follow-up work. The homepage offers a free start and publishes plan details on its pricing page. It is designed to support research organization, not to certify findings. A limitation is that generated summaries, citations, and evidence links can be incomplete or incorrect, so researchers must open and verify the underlying papers and follow their institution’s academic-integrity rules.
