小满 Xiaoman is an open-source, local-first personal finance agent that operates primarily through conversation. It is designed to help users record expenses, track investments, manage budgets, and generate financial reports by interacting in natural language. The software stores all financial data locally in an SQLite database, ensuring that data never leaves the user's machine. It supports multiple AI models, including DeepSeek, Qwen, Claude, OpenAI, and Doubao, through a unified LiteLLM integration layer. The agent exposes its financial tools via the MCP protocol, allowing integration with MCP clients like Claude Code and Cursor. The interface is organized around five tabs: Overview, Holdings, Market, Ledger, and Ask AI, reflecting common investor mental models. All numerical calculations are performed by a deterministic analysis kernel, while the AI is only used for classification and text generation, preventing the model from altering data. The system includes features such as encrypted backups, streaming responses, and a production-grade architecture with FastAPI and LangGraph.
