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
