Nodus Research FAQ
How does Nodus Research help with academic literature review?
It indexes PDF, EPUB, and HTML attachments from Zotero collections, then uses a local quantized E5 model for search. It can extract themes, agreements, contradictions, and research gaps, and build idea graphs. Citations stay tied to page and passage.
How does Nodus Research compare to NotebookLM?
Compared to NotebookLM, Nodus Research is local-first and free, with no paid cloud plan. It keeps vaults and search indexes on your computer, connects Zotero collections, and ties citations to page and passage. It also ships a Zotero plugin so you can keep your existing library.
Which trade-offs should I expect when adopting Nodus Research?
You bring your own LLM key or a local model for generation, though embeddings can stay local. It is a smaller project than Obsidian or Notion, so expect install and plugin friction. There is no published commercial SLA or hosted workspace.
What kind of user or team does Nodus Research fit best?
It fits academic researchers, teachers, and students who want a local-first workspace for research, teaching, and study. Because it works as a Zotero layer, it suits people who already maintain a Zotero library. Those who prefer open-source, free tools and are comfortable managing their own LLM keys or local models will find it most appropriate.
How is Nodus Research priced?
Nodus Research is free to use, with no paid plan required. There is no paid cloud plan on the site. The source is open under GNU AGPL on version 4.x.
Can Nodus Research work with my existing Zotero library?
Yes. Nodus Research ships a Zotero plugin (nodus-zotero.xpi) and can connect Zotero collections. It indexes PDF, EPUB, and HTML attachments, so you can keep your existing library and search it locally.
How does Nodus Research handle citations in AI answers?
It provides answers with passage and page citations, rather than a bare chatbot dump. This keeps citations tied to page and passage. The desktop app can also extract themes, agreements, contradictions, and research gaps.
Does Nodus Research require an internet connection or embedding API key?
No. Vaults and search indexes stay on your computer, and search uses a local quantized E5 model with no embedding API key. Optional online models are opt-in, so you can work fully offline if you choose.
