LuminAI Data Analyst is a Python-based AI assistant tailored for data exploration and reporting. Built on OpenAI GPT and LangChain, it seamlessly ingests structured data files (CSV, XLSX, JSON), performs automated cleaning, computes descriptive statistics, and visualizes key metrics with Matplotlib or Plotly. Users interact via command-line or API, posing questions in plain English to generate customized charts, summary tables, and narrative insights. The agent can export results as PDF or HTML reports and integrate with BI tools. It streamlines repetitive analysis tasks, turning raw datasets into actionable recommendations and saving time for analysts, developers, and business stakeholders. Advanced users can extend its modules or customize prompt templates for domain-specific workflows.
