Best for
- Researchers who want to explore a field by following citations visually, starting from papers they already know.
- People who want a free plan with a clear, small set of limits to try first.
Not a fit if
- You need to know the exact Pro price and billing method. The page shows $10 per month with an asterisk and does not say which billing it applies to.
- You want direct answers to questions. Litmaps is about discovery and mapping, not question answering.
- You need more than 2 maps on the free plan. Free allows 2 Litmaps with up to 100 papers per map.
Litmaps describes itself as a literature discovery tool. You start from papers you already know, and it builds a visual map of related work from citation links, with alerts for new papers. That makes it a different kind of tool from the question-answering and writing tools in this set.
The free plan lists its limits plainly: basic search, up to 20 inputs, 2 Litmaps and 100 papers per map. The Pro plan lists unlimited inputs, papers and Litmaps.
On price, the page shows $10 per month for Pro with an asterisk about discounts for your country. It has options for annual billing and monthly billing but does not say which one the $10 applies to. We therefore do not claim a billing method, and this page marks both as not verified.
For where Litmaps fits next to the other tools, read the literature review guide and the free plans comparison. Everything here comes from the vendor’s pages, listed under Sources. Nobody has run the tool in real work for this profile.

What looks good
- A Free plan with clearly listed limits (20 inputs, 2 Litmaps, 100 papers per map).
- The Pro plan lists unlimited inputs, papers and Litmaps.
- Built around citation maps and alerts for new papers, a different job from question-answering tools.
Limits and open questions
- The Pro price is shown as $10 per month with an asterisk, and the page does not say whether it is billed monthly or billed annually. Both billing methods are marked not verified.
- The Education and Commercial groups on the pricing page mean the price you see may depend on which one applies to you.
- Not a tool for reading or summarising papers; you still read the papers you find.
