Highlight a claim, get an evidence-backed verdict before you share it
Check a claim directly from the page you are reading instead of pasting it into a separate tab.
Each check returns an assessment of the claim along with the reasoning and supporting material behind it.
Statements that look misleading are surfaced clearly so you can slow down before sharing them.
Developers and teams can programmatically verify text and build fact-checking into their own tools.
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.
