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.

40+ AI research tools that turn papers, PDFs, videos, and decks into cited insights
Webpage, PDF, YouTube, and presentation tools return the same schema every time—TL;DR, summary, key insights, and statistics—so outputs are scannable in seconds.
YouTube videos are fetched and transcribed into a chronological timeline, and decks get a slide-by-slide walkthrough instead of one generic executive summary.
Save any tool output, edit it in a rich-text editor, organize it into project folders, run side-by-side comparisons, and chat with your saved files.
Build a citation library in APA, MLA, and other styles with BibTeX export, and generate publication-ready LaTeX tables or PNGs from scratch.
