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 workspace for searching, reading and connecting papers
Search a corpus of hundreds of millions of papers by meaning, with new content indexed continuously from thousands of journals.
Ask questions of any paper and place multiple studies side by side to spot agreements, contradictions and the bigger picture.
A visual graph maps how papers and concepts connect, helping you find adjacent work you would otherwise miss.
Upload your own PDFs, capture reading notes, and organize everything in a single research workspace.
