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.
AI-assisted systematic review software for screening, extraction, and evidence synthesis at scale
The Systematic Auto-Resolver deduplicates up to 200,000 references using your own inclusion and exclusion protocol with one click.
ResearchPilot delivers zero-shot relevance ratings, an AI Analyzer, an AI Reviewer, and auto-extraction to speed up search, screening, and data capture.
Work through title, abstract, and full-text screening with inclusion and exclusion tagging, conflict resolution, and blinded reviewer modes.
Capture structured study data with configurable extraction fields, apply PICO frameworks, and export results with auto-generated PRISMA diagrams.
