Moonshot AI's long-context assistant for research, coding, and agentic work
Feed in lengthy documents, papers, or code and ask questions across the full text without losing earlier context.
Hand over multi-step jobs that involve planning, browsing, and tool use instead of only single-turn answers.
Generate structured research reports, slide decks, and formatted documents directly from your prompt or source files.
Extend capabilities with plugins and set recurring jobs so the assistant keeps working between sessions.

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.
