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.

Academic proofreading, plagiarism checking and AI-powered writing tools in one place
A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter.
Scans your document against a large web and publication database to surface potentially unoriginal passages before submission.
Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural.
Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search.
