Litmaps maps citation networks so you can see how papers connect, spot the seminal ones, and catch new work as it publishes — handy for systematic reviews and expanding out from a handful of seed papers. The bigger 2026 story: Litmaps bought its own rival, ResearchRabbit, in May 2025 and is folding the two together, while ResearchRabbit keeps running separately for now on its own free tier. The free plan is genuinely thin — 20 search inputs, two maps capped at 100 articles each — and Pro runs $10/mo (or $120 billed annually) with a 75% discount if you've got a university email. Alerts are configurable daily on Pro, monthly on Free, not the weekly digest some listings describe. Public reviews are sparse (G2's profile is unclaimed, Trustpilot has a single review), so weigh the company's funding and acquisition news more than star ratings here.
What people say
In May 2025, Litmaps bought its own biggest rival, ResearchRabbit, folding a second citation-mapping tool into a company that had just raised roughly $1 million and doubled its ARR to around the same figure beforehand. ResearchRabbit keeps running as a separate free product for now while the two get merged — an unusual position for a company that spent years being compared, both favorably and unfavorably, to the thing it now owns.
The core product hasn't changed much: set a research interest and Litmaps builds a citation graph that updates as new papers publish, useful for finding seminal work and catching gaps before a systematic review. The free plan is thin by design — 20 search inputs and two maps capped at 100 articles each, with only a monthly alert digest rather than anything close to real time.
Pro runs $10 a month, or $120 billed annually, and unlocks unlimited inputs, unlimited maps, and configurable alerts that can run daily rather than the vague 'weekly' cadence some older write-ups still describe. Anyone with a university email gets 75% off automatically. Team and Enterprise pricing is quote-only.
One caveat worth flagging: Litmaps' public review footprint is unusually thin for a company this size — G2's listing is unclaimed with no reviews, and Trustpilot has exactly one. Judge it on the funding, the acquisition, and a free-plan test run rather than star ratings that barely exist yet.
