AI research assistant for citation-backed reading, note-taking and writing
Ask questions across a whole library of PDFs, papers and web pages and get answers grounded in the passages they came from.
Draft essays, reports and papers where sources are linked and citation styles are handled automatically.
Highlight, annotate and take structured notes inside documents so your reading turns into reusable material.
Organise references, compare findings across sources and build a review outline from a single collection.
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.
