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.

AI search and comparison for experimental protocols
Search experimental methods in plain language and get protocol-level results rather than only paper titles, so you can find how a technique was actually run.
Line up protocols from different papers or labs next to each other to spot where they agree and where they diverge, which is central to reproducing a method.
Pull structured detail out of documents and protocols so steps, reagents and conditions are easier to scan and reuse.
Browse and contribute to a growing knowledge base of experimental protocols, helping your lab and others find proven methods faster.
