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 engine that turns advanced-materials discovery into a search
Chemistry, structure, architecture and process are held in one object, giving the engine a unified substrate that molecular-only models lack.
Candidate materials are generated from the experiments that surround them in vector space, so predictions stay anchored to real-world results.
The engine treats negative results as high-value information, using them to rule out large regions of the design space faster than positive results alone.
For teams without materials expertise, Mimir's scientists take requirements and deliver a working prototype rather than just a report or a model.
