Do you like to talk to your data?
Overview
OpenDataChat is a natural language data analysis platform. Upload your datasets, ask questions in plain English, and get instant insights. No SQL knowledge required—just conversation.
The system combines large language models with traditional data analysis to turn raw data into actionable intelligence through simple, natural conversation.
What It Does
- Upload datasets in multiple formats (CSV, Excel, PDF, JSON, or ZIP with multiple files)
- Ask questions about your data using everyday language
- Get instant answers with relevant charts and visualizations
- Export results for reports and presentations
- Share secure data portals with others
How It Works
OpenDataChat analyzes the structure of your uploaded data and creates a searchable database. When you ask a question, the system translates your natural language query into data operations and returns results with visualizations.
Architecture
- Backend: ASP.NET Core Blazor server, FastAPI (Python), SQL Server database, Qdrant vector search
- Processing: Automatic schema detection, natural language to SQL translation, semantic search with embeddings
- Frontend: Real-time interactive chat interface with live visualizations
- Storage: All data securely stored on Azure Blob Storage
