A free, AI-powered academic search engine for 240M+ papers across every scientific field
Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.
An AI writing workspace that drafts from page-cited evidence and reviews your document's integrity
The ChatPDF tool answers questions about a paper using retrieved excerpts and verifies citations verbatim, so answers stay tied to a specific page.
Turn an approved outline and selected evidence into a draft in a resumable workspace that carries your quotes forward without pasting blind.
Findings must quote your document verbatim and are discarded if the excerpt cannot be found, so every flag points to something you can check.
The AI Detector surfaces review signals you can inspect rather than a single black-box percentage, and is framed as supporting evidence.
