AI-powered visual discovery of scientific knowledge
Every search produces an interactive concept map in which related research outputs are grouped into labeled, clickable clusters instead of a single flat list.
Searches more than 400 million records in over 400 languages pulled from more than 11,000 sources through the BASE aggregator.
Beyond journal articles, results span datasets, software, images, and other research objects, giving a broader picture of a topic.
Maps are generated from metadata rather than synthesized text, so what you see corresponds to real indexed records.
AI-native workspace for literature reviews and auditable systematic reviews
Ask a research question in plain language and get a synthesized answer drawn from PubMed, arXiv, OpenAlex and Semantic Scholar, with every claim linked to its source paper.
Run PRISMA-style reviews with a predefined protocol, recorded screening decisions, dual independent reviewers and a conflict resolver, and a PRISMA diagram generated from your actual counts.
Import from Zotero or Mendeley, add papers by DOI, and get metadata and open-access PDFs fetched automatically, with annotations and notes that feed every other workflow.
Define custom extraction columns and have AI fill them across many papers, with each value linking back to the sentence it came from, exportable to CSV or Excel.
Real-time AI answer engine and research workspace combining live web citations with frontier reasoning models.
