The Verdict
Perplexity is built for researchers and knowledge workers, with a focus on ai-search and source-citations. Research Rabbit targets researchers and phd students and leads with paper-discovery and network-visualization.
Research Rabbit uses custom enterprise pricing, while Perplexity starts at $20/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Both tools are a solid fit for researchers — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
