For researchers, students, and serious writers
Grounded in research papers from Semantic Scholar, OpenAlex, and PubMed.

Citations are verified against the same databases university libraries use. We don't make references up — we look them up, fetch the PDF when it's open access, and cite the canonical metadata.
Primary discovery layer across 200M+ papers. Powers Deep Research's first-pass paper sweep.
250M+ scholarly works, open metadata. Cross-checked against Semantic Scholar for coverage in niche fields.
NIH's biomedical and life-sciences index. Automatically engaged when Deep Research classifies a query as medical or biological.
Open-access full-text archive linked to PubMed. Where we pull the actual PDF when the paper is OA.
The authoritative DOI resolver. Every citation is verified against Crossref's canonical metadata before it lands in your bibliography.
Open-access PDF discovery across 50M+ articles. Finds a legal open version when the primary URL is paywalled.
Preprint server for physics, math, CS, and statistics. Resolved by DOI as an Unpaywall fallback so the PDF reaches your bibliography.
Diagrams and figures with explicit Creative Commons licenses. Sourced by Study Guides with author + license cited inline.
Every fetched PDF is attached to your document — no broken links three months later. License and attribution are rendered next to every borrowed figure. The bibliography is renumbered automatically when you cite a new paper.
One editing surface for prose, math, code, tables, citations, images, audio, and video.
The capabilities that aren't available together anywhere else.
