What is ResearchRabbit+?

RR+ is the premium tier of ResearchRabbit, offering advanced features to take your literature review to the next level.

Written by Digl

The core of ResearchRabbit is available for free, which thousands of researchers around the world use to improve tasks like citation chasing, note-taking, and visual citation mapping.

Beyond the free tier, ResearchRabbit+ enables you to level up your search efficiency and organisation. RR+ adds a layer of powerful features on top of ResearchRabbit’s core functionality, which can be combined in creative ways to tackle a diverse range of research challenges.

What’s included in RR+?

Find and narrow

See every paper in your search’s extended network on one chart, stacked by year of publication.

  • Find where two or more topics meet, using And, Or and Not

  • See how an overlap has grown over time, and spot where it’s still thin

  • Open your matching articles as a Rabbit-hole, and merge the best ones back in as Seeds

A powerful suite of options for refining your search. Narrow by keyword, publication date, journal quality (SJR quartile and H-index) and open access, in Grow and across your whole network in Analyze. Then save what matches to a collection, or remove it in one go.

  • Cut through dominant topics to unearth niche articles

  • Find foundational articles, or the current state of the art

  • Adhere to your university’s literature review requirements

Connect and keep up

Keep your Zotero collections and ResearchRabbit in step.

  • Papers and notes you add on either side appear on the other

  • Start a search from a synced collection, so a whole Zotero collection becomes your Seeds

Hear about new papers on your topic without searching again.

  • Choose email or in ResearchRabbit, weekly or monthly

  • Watch your whole library, or only the collections you choose

Badges that flag papers to be careful with, so you find out before you cite.

  • Flags retractions, unusual citations and AI-generated content

  • Shown in your search and in your collections

Studying or working at a university? Your library may already have RR+ access for everyone, so it’s worth asking them.

Who should subscribe to RR+?

Subscriptions are becoming a big part of monthly expenses, so it’s wise to approach any newcomers with scrutiny. Below are some prompts to get your brain whirring about whether RR+ deserves a spot.

Researchers who are short on time

Look, this one is almost everyone, but it’s worth reflecting on. Research projects are driven by early findings in the literature, so accelerating your path to a stable literature survey is going to make a serious impact on your research trajectory.

Researchers reviewing 50+ articles

For large literature reviews it’s particularly hard to feel confident that you’ve covered everything. RR+ can act as a safety net for when manual checks become unwieldy (or even impossible):

  • Scan for potential holes in your literature review using as many as 300 Seeds in a single search

  • See every paper in your search’s extended network on one chart with Analyze

  • Add an extra layer of reassurance using keyword, journal, and date range filters.

Researchers working in a niche field

Search engines can bias towards articles with a lot of citations, which tend to come from more popular fields. The process of unearthing articles for niche subtopics can often become either time-consuming or tunnel-visioned.

  • Narrow your search towards subtopics in a controlled way using advanced search filters

  • Target the intersection between two topics in Analyze, to find other niche literature that may have been obscured by dominant fields

Researchers working on multiple papers

When working on multiple research papers it can be easier to keep separate sets of articles and notes. This way, working on one paper won’t affect the data that underpins your others.

  • ResearchRabbit+ allows you to create multiple Projects, allowing you to separate articles, collections, and notes for each of your papers.

Researchers who use Zotero

Keep your Zotero library and your ResearchRabbit collections in sync, so the papers you find are ready to cite.

Researchers who want to keep up with new work

Set Project Alerts, and hear about new papers on your topic without searching again.

Researchers on a tight budget

Research is not always well funded, and we understand that budgets can be tight. If RR+ is not feasible right now, that is completely okay.

That is exactly why the ResearchRabbit Free tier exists. You can still do excellent research with the free version. The core experience remains powerful and useful.

🌏 Reminder: RR+ is available at a discounted rate for some countries! Check our RR+ Country Discounts guide for more information.

RR+ vs Free ResearchRabbit

In addition to Advanced Search Filters and Analyze, RR+ also provides unlimited functionality across the application which isn’t available on the free tier. This includes:

You can sign up for RR+ anytime in the application. Plans are flexible, allowing you to cancel and re-subscribe at any time. To ensure equitable access for researchers across the globe, we offer country parity pricing.
