Sources Hub

Sources Hub is how you grow your project’s library. In the spirit of NotebookLM, it mines the references you already have, finds the gaps, and adds curated sources in one click — so your agents have real literature to write and cite from.

What it does

Sources Hub brings three ways of finding sources into one panel: mining references out of the papers already in your library, searching the open web for what’s missing, and pasting in a source you already have. Whatever you add lands in your project library, ready for the Full Draft Writer and Claim Check to use.

Discover sources

Point Sources Hub at your existing library and it reads the references cited inside those papers, surfacing the works your sources themselves rely on. It also identifies gaps — topics your draft touches but your library doesn’t yet cover — and proposes sources to fill them.

Add to your library

1. Review the candidates

   Sources Hub lists discovered and searched results with enough detail to judge relevance.

2. Add with one click

   Add a source to your project library directly from the panel — no copying identifiers between tools.

3. Cite it

   Once in the library, the source is available to every agent and to your own citations.

Web search and paste

Need something specific? Search the web from inside Sources Hub, or paste a URL or reference you already have. You can also import existing reference files — BibTeX, RIS, and CSL-JSON — into the library; see library & sources.
