Litmaps
Draws a citation map you can steer, so the shape of a literature becomes visible rather than being a list of titles.
Draws a citation map you can steer, so the shape of a literature becomes visible rather than being a list of titles.
The categories Litmaps is listed in, and how strong a fit it is in each.
Web research, deep research, books, academic papers, citations, news, fact-checking.
Litmaps has a free plan. Free, capped rather than trial-limited: 2 Litmaps with 100 articles per map, basic search taking up to 20 seed inputs, monthly literature alerts and no collaboration
Acquired ResearchRabbit in May 2025, so both products now come from the same company. They still work differently and are listed separately.
Also from Litmaps: ResearchRabbit.
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 →You upload the sources and it answers only from them, linking every sentence to the passage it came from. The strongest verification pattern here.
View Gemini Notebook →Where Litmaps sits in the wider category pages.
Built for this — Web research, deep research, books, academic papers, citations, news, fact-checking.
Yes โ Free, capped rather than trial-limited: 2 Litmaps with 100 articles per map, basic search taking up to 20 seed inputs, monthly literature alerts and no collaboration. The cheapest paid tier is Pro, at $12.50/mo month to month or $10/mo billed yearly.
Draws a citation map you can steer, so the shape of a literature becomes visible rather than being a list of titles. It is listed under Search, Research & Academics, and this is what it is built for.
A map is a prompt to read, not a substitute for reading. The free tier stops at 2 maps of 100 articles each, so a real review needs Pro, and Pro is priced on separate education and commercial tabs. Overlaps ResearchRabbit, which is now the same company.
6 tools do comparable work: Connected Papers, Consensus, Elicit, EvidenceHunt, Gemini Deep Research, Gemini Notebook. 6 of them have a free plan.
