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.
Computational knowledge engine for expert answers
Enter a question in natural language or via math input and get computed answers with plots, units, and context.
Solve algebra, calculus, differential equations, statistics, and more, with worked solutions on Pro.
Pull facts, conversions, and comparisons across geography, history, money, nutrition, and more.
Auto-generate charts, plots, and visual representations of results.
