Pros & Cons

Research Rabbit

  • Genuinely free-forever core tier with unlimited searches and collections, not a stripped-down trial
  • Massive database coverage — over 310 million academic articles
  • RR+ pricing is discounted by country purchasing power parity, improving global accessibility
  • Free tier’s 50-seed-article limit may constrain larger literature review projects
  • Advanced filters and multiple simultaneous projects require the $10/month RR+ tier
  • Transitioned from fully grant-funded free access to freemium in 2025, a meaningful business model change

ChatGPT

  • Largest user base and ecosystem of any AI assistant, with the most third-party integrations
  • Genuinely broad capability across writing, coding, research, and file analysis
  • Custom GPTs allow tailoring the assistant to specific repeated tasks
  • Frequent model updates keep it competitive on raw capability
  • Free tier has usage limits and access to a lower-tier model than paid plans
  • Can produce confident-sounding but incorrect information, especially without browsing enabled
  • Breadth can mean less depth than a tool purpose-built for one specific workflow
  • Data usage and training policies require attention for sensitive or regulated work
