  • Intelligent, privacy-first financial analysis platform using Local LLMs and Model Context Protocol (MCP).
  • Agentic architecture with LLM acting as Senior Auditor for accurate financial summaries.
  • Local & Private: Runs entirely on your machine via Ollama; no data leaves your environment.
  • Agentic Reasoning: Uses granite3.3:8b to interpret natural language and map to SQL-backed tools.
  • Accurate Arithmetic: Offloads summations and aggregations to SQLite engine for 100% accuracy.
  • Smart Filtering: Automatically distinguishes real spending from internal transfers.
  • Vendor Name Normalization: Uses granite3.3:2b to normalize vendor names into readable merchants.
  • Persistent Context: Maintains chat history across dashboard views using React state lifting.
  • Modular, multi-tier architecture for extensibility and local-first execution.
  • UI (React): Dashboard for visualizing transactions, uploading statements, and interacting with AI.
  • Application API (Python/FastAPI): Backend for PDF parsing, transaction categorization, and summaries.
  • MCP Server (Python/FastMCP): Exposes SQLite-backed financial data to LLM via deterministic tools.
  • Local LLM Runtime (Ollama): Processes user intent and orchestrates tool calls.
  • Setup requires Ollama, Node.js, Python, SQLite, and uv for dependency management.
  • Workflow: Upload PDF statements → parsing → normalization → storage → manual categorization.
  • Manual Transactions: Log expenses not on statements, fixed costs, utilities, and cash expenses.
  • Dashboard Features: Aggregated totals, trends, fixed vs. variable spending analysis.
  • Senior Auditor Chat: LLM uses MCP Tools for verified financial analysis queries.
  • Future Features: Auto-categorization, machine-learning vendor normalization, AI-generated charts.
