Pros & Cons

Litmaps

  • Free plan is genuinely usable (20 inputs, 100 articles, 2 maps), not just a stripped-down teaser
  • Visual citation mapping provides genuine discovery value beyond simple keyword search
  • Used by 400,000+ researchers worldwide, demonstrating real adoption in academic research
  • Free plan’s limits (2 Litmaps, 100 articles/map) restrict larger-scale literature review projects
  • Unlimited access requires the Pro plan at $10/month (education pricing, annual billing)
  • Team collaboration and configurable alerts require the higher-priced Team plan

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
