What it is

Fetches a URL a Gemini Notebook (formerly NotebookLM) user added as a source to their notebook. The former agent string Google-NotebookLM is documented as supported until August 2026. Google publishes fetcher addresses in two files — user-triggered-fetchers.json and user-triggered-fetchers-google.json — and does not say per fetcher which one applies, so verification means checking both; this index mirrors both.

What blocking it costs you

A user who deliberately added your page as a research source gets nothing. This is a citation-shaped fetch, not a training crawl.
