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.
Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
