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 writing assistants built by researchers, for academic publishing workflows
Named assistants such as Outline Oracle, Abstract Aid, Intro Infer, Lit Linker, Method Maker, Result Reveal, Conclude Craft and Thesis Thread each target one part of an academic manuscript.
Web Deep Research surveys academic and general sources for broad topic overviews, while Scholarly Deep Research targets peer-reviewed papers and systematic enquiry.
An upcoming SLR capability aims to generate comprehensive literature reviews that follow academic standards and surface new hypotheses to investigate.
Output is tuned to scholarly style and structure, so drafts read like research prose rather than generic marketing copy.
