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 search and comparison for experimental protocols
Search experimental methods in plain language and get protocol-level results rather than only paper titles, so you can find how a technique was actually run.
Line up protocols from different papers or labs next to each other to spot where they agree and where they diverge, which is central to reproducing a method.
Pull structured detail out of documents and protocols so steps, reagents and conditions are easier to scan and reuse.
Browse and contribute to a growing knowledge base of experimental protocols, helping your lab and others find proven methods faster.
