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.

Don't trust the science — verify it, with evidence on both sides
Enter any scientific or health claim and receive a structured breakdown covering both the evidence for it and the evidence against it.
Every analysis links out to journals, PMC articles, and scholarly indexes so the underlying studies remain verifiable and traceable.
Beyond pro and con, the engine writes a synthesis that weighs the two sides and notes where the evidence remains uncertain or contested.
Browse a public feed of community-submitted analyses — including topics like cell biology — to see how the engine reasons across different claims.
