AI research platform for reading, understanding and writing scientific papers
Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
