WealthOS: A Local LLM-Powered Intelligent Investment Analysis Platform for India's Capital Market

WealthOS is an AI investment advisory system designed specifically for India's capital market. It addresses the lack of professional AI investment tools in the Indian market through local Mistral-7B model inference, modular data collectors, and tool-augmented AI workflows, providing structured, data-driven stock analysis and investment recommendations. The project is positioned as a technical demonstration and learning reference, not production-ready.

As one of the world's fastest-growing major economies, India's capital market (NSE/BSE) attracts a large number of investors. However, there is a relative scarcity of professional AI investment analysis tools tailored to the Indian market. Existing tools either rely on expensive cloud APIs or lack deep understanding of India's market characteristics. The WealthOS project targets this market gap to build a localized intelligent platform.

Local LLM Inference Layer

Uses the Mistral-7B Q4_K_M quantized model, running locally via llama.cpp. Its advantages include zero API cost, data privacy (sensitive data does not leave the local environment), low latency, and offline availability.

Tool-Augmented AI Architecture

Adopts an Agent mode where the agent dynamically selects tools: data collection tools (stock prices, fundamentals, technical indicators, etc.) and analysis tools (fundamental analyzer, technical analyzer, etc.), ensuring responses are based on real data rather than hallucinations.

Modular Data Pipeline

• Collector layer: Obtains raw data from Yahoo Finance, Screener.in, NSE Python, etc.
• Analyzer layer: Computes financial ratios, generates technical indicators, and builds context summaries.

DuckDB Cache Layer

An embedded database that stores API responses, reducing repeated calls, supporting complex queries, and providing fast local access.

WealthOS adapts to the Indian market at multiple levels:

• Stock codes: Supports NSE/BSE formats.
• Regulatory compliance: Considers the SEBI regulatory framework.
• Currency unit: Uses Indian Rupees (INR) as the benchmark.
• Local data sources: Integrates India-specific financial data providers.
• Investment tools: Supports analysis of popular Indian mutual funds and gold investments.

User Interface

Provides three tabs via Gradio:

• Stock Analyzer: Triggers comprehensive single-stock analysis.
• Ask WealthOS: Natural language investment Q&A.
• Market Dashboard: Market overview and data refresh.

Practical Application Value

For Indian investors, it can:

• Quickly generate comprehensive assessments of stock fundamentals and technical aspects.
• Answer investment questions such as valuation rationality.
• Track portfolio performance and risk exposure.
• Obtain market insights based on news sentiment.

WealthOS is a technically solid and clearly positioned AI investment analysis project. It proves that consumer-grade hardware (such as Google Colab T4 GPU) can build fully functional financial AI applications through reasonable architecture and quantization technology. Its architectural pattern (local LLM + tool-augmented Agent + modular data pipeline + domain specialization) can be extended to other financial market scenarios, making it a reference implementation worth in-depth study for developers and investors.
