Research, edit, and write with AI at your side
A ChatGPT-style assistant tuned for scholarly writing, with autocomplete, paraphrasing, summarization, and first-draft generation.
Search relevant academic literature inside the app, then keep sources organized in a reference list beside the editor.
Upload your papers and ask questions about them, so you can interrogate a source without leaving your document.
Automated functions help streamline literature reviews and other repetitive research tasks.
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.
