About ResearchRabbit
What is ResearchRabbit (2026 update)
ResearchRabbit is an education and translation tool built for academic research, letting users discover, visualize, and organize scholarly papers by starting from a handful of seed articles and expanding outward through citation and co-authorship connections across a database of more than 310 million articles.
What is new in 2026
ResearchRabbit went through a major redesign that changed how the app looks and works compared to versions used before late 2025. The classic Network Graph view was removed, replaced by a view that lets users customize the X and Y axis sorting and adjust node size directly, and BibTeX upload plus Zotero connection moved into the app’s Library section rather than living as separate entry points. The bigger shift is business model: after years as a fully free tool, ResearchRabbit introduced a paid premium tier, ResearchRabbit+ (RR+), in 2025 and has kept it running through 2026, moving the product from free to freemium while explicitly keeping a full-featured free plan in place.
Key features
- Citation and co-authorship network discovery starting from seed articles
- Unlimited collections for organizing papers by project or topic
- Collaboration features for sharing collections with co-authors or advisors
- Library uploads plus BibTeX and Zotero import, now grouped under the Library section
- Customizable axis sorting and node sizing for visualizing paper relationships
- Signals alerts on RR+ for tracking new papers relevant to a project
- Multiple simultaneous projects on RR+ for researchers juggling several literature reviews
Pricing in 2026
| Plan | Price | What you get |
|---|---|---|
| Free | Free, forever | Up to 50 seed articles, unlimited search across 310+ million articles, unlimited library and collections, core search settings |

| Institution | Custom quote | Volume discounts, library integration, multi-user management, usage analytics, dedicated support |
ResearchRabbit also runs purchasing-power-based discounts on RR+ for researchers in more than 100 countries, so the effective price can be lower than $10/month depending on location.
Who should use it
ResearchRabbit fits students, PhD candidates, and academic researchers doing a literature review who want to visually map how papers connect rather than searching keyword by keyword. The free plan alone covers most individual literature reviews since it includes unlimited search and collections; RR+ becomes worth it mainly for larger projects that need more than 50 seed articles, alerts on new papers, or several active projects running at once. Labs and universities that need shared accounts and usage reporting are better served by the Institution plan. Because the tool is built around visual exploration rather than keyword search, it also suits researchers entering an unfamiliar field who want to see how key papers relate to each other before committing to a narrower reading list.
Limitations and alternatives
The redesign removed the original Network Graph view that many long-time users relied on, so anyone returning after a break should expect a different interface and some relearning. RR+ pricing also varies by country through parity-based discounts, so the number you see may not match what a colleague elsewhere pays. For comparison, Connected Papers builds strong single-seed similarity graphs but does not support multi-seed collections, Litmaps adds a timeline view showing how a field evolved over time, and Elicit is better suited to structured, PRISMA-style systematic reviews rather than visual citation mapping.
