• Prior & follow-up research — See Prior Works and Derivative Works at a glance
• Great for early research exploration — Quickly grasp the key papers and trends in a specific field
• Free tier available — Up to 5 graphs per month for free

Limitation: There's nothing you can do after the visualization. It doesn't offer features for analyzing paper contents, finding research gaps, or writing papers.
