The research assistant that verifies every citation before it spreads
Each reference is resolved against real bibliographic records, and incorrect, retracted or fabricated citations are flagged before they propagate into your paper.
Upload and search across millions of papers in major scientific databases to surface similar articles that common platforms miss.
References are stored as organized, connected entries with citation keys, turning scattered PDFs into a linked knowledge base.
Draft and refine in the same workspace while citing straight from your verified library.
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.
