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.

Ask questions of your PDFs and ebooks with a privacy-first AI reader
Submit natural-language questions about an uploaded PDF or ebook and receive direct, content-grounded answers instead of search results.
Accepts PDFs, ebooks and structured text such as TXT, CSV and JSON, so papers, manuals and datasets can share one workspace.
Condense long documents into quick overviews or pull out the specific facts and figures you need.
No account creation or password management — log in with your Google account in a couple of clicks.
