The categories Gemini Notebook is listed in, and how strong a fit it is in each.
Web research, deep research, books, academic papers, citations, news, fact-checking.
Gemini Notebook has a free plan. Free, and the core product is not gated: what a paid plan buys is headroom — a bigger notebook, more sources per notebook and higher limits on Audio and Video Overviews and Slides
Standalone valuation is not meaningful for a wholly owned lab. Screening subsidiaries on funding metrics produces garbage — they belong in the model-layer comparison, not the capital-layer one.
Also from Google DeepMind: Gemini, Gemini Code Assist, Gemini Deep Research, Gemini image generation, Gemini in Workspace.
Tools that do comparable work, best fit first, drawn from the catalogue rather than hand-picked. Every one is listed whether or not there is money in it for us.
Builds a similarity graph from citation data rather than from a language model, so nothing in the output is generated and there is nothing to hallucinate.
View Connected Papers →Searches published papers and tells you how many of them support a claim, which turns a yes-or-no question into a count you can inspect.
View Consensus →Searches actual papers and extracts findings into a table you can check, one row per study, rather than answering in prose.
View Elicit →Scoped to clinical evidence and built with practising clinicians, so the filters match how medical literature is actually appraised.
View EvidenceHunt →Runs a multi-step search across dozens of sources and returns a structured, referenced report. Strong first pass on an unfamiliar field.
View Gemini Deep Research →Draws a citation map you can steer, so the shape of a literature becomes visible rather than being a list of titles.
View Litmaps →Where Gemini Notebook sits in the wider category pages.
Built for this — Web research, deep research, books, academic papers, citations, news, fact-checking.
Yes — Free, and the core product is not gated: what a paid plan buys is headroom — a bigger notebook, more sources per notebook and higher limits on Audio and Video Overviews and Slides. The cheapest paid tier is Google AI Plus, at $4.99/mo month to month or $4.17/mo billed yearly.
You upload the sources and it answers only from them, linking every sentence to the passage it came from. The strongest verification pattern here. It is listed under Search, Research & Academics, and this is what it is built for.
Deliberately limited — it will not answer what your documents do not cover, and cannot tell you whether they are any good. Paid headroom comes from a Google AI subscription rather than a plan of its own. It was called NotebookLM until Google renamed it in July 2026, and notebooklm.google.com is still where it opens.
6 tools do comparable work: Connected Papers, Consensus, Elicit, EvidenceHunt, Gemini Deep Research, Litmaps. 6 of them have a free plan.
