Knowledge-grounded AI writing, from uploaded documents to full drafts
Upload PDFs, documents and notes, then have the AI compose long-form text grounded in those sources instead of generic web knowledge.
Generate full book-length drafts — chapters, outlines and structure — from a topic, brief or uploaded reference set.
Organize uploaded references into a searchable knowledge base you can query and write from.
Support for citation-aware output helps you trace generated claims back to the source documents you provided.
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.
