Explore the academic literature as a visual graph of related papers
Each graph places the seed paper among its most closely related works, clustered by how often papers are cited together or share references.
Separate perspectives show what a paper builds on and what later work builds on it, which is ideal for tracing a research lineage.
Start from a paper title, DOI, URL or proceedings link, so you can enter the graph from whatever you already have at hand.
A ranked list view lets you browse related publications by relevance when you need specifics rather than an overview.
Highlight dense research text and get plain-language explanations instantly
Select any confusing sentence or term and receive an immediate plain-language explanation that accounts for the rest of the paper.
Shift the reading level from beginner-friendly to expert-detail so the explanation matches your background.
Ask questions and get answers grounded in the document's actual content, with references back to the relevant sections.
Produce a smart outline, key-point extraction, and concept relationship views without reading the entire paper first.
