QueryWise AI – Natural Language SQL Copilot

QueryWise AI – Intelligent Natural Language SQL Copilot QueryWise AI is an AI-powered analytics assistant that makes data exploration simple and accessible. Instead of writing SQL manually, users can upload CSV, TSV, or Parquet datasets and ask questions in plain English. The application automatically detects the dataset schema, generates SQL, executes it using DuckDB, and displays the results through an interactive dashboard. The goal of QueryWise AI is to reduce the learning curve for SQL and enable analysts, students, business users, and developers to explore data more efficiently. Traditional analytics tools require users to understand database structures and SQL syntax before extracting insights. QueryWise AI removes this barrier by translating natural language into executable SQL. The application features a modern React frontend and a FastAPI backend. After uploading a dataset, users can ask questions such as "How many orders are there?", "Show total sales by category", or "Who are the top customers?". The backend generates and validates SQL queries, executes them using DuckDB, and returns results along with execution statistics. Key Features Natural Language to SQL conversion CSV, TSV, and Parquet dataset upload Automatic schema detection FastAPI backend with DuckDB execution Interactive React dashboard SQL validation and query history Offline intelligent fallback engine Docker-ready deployment QueryWise AI is built with a modular architecture, making it easy to extend with cloud databases, authentication, advanced AI models, and enterprise analytics. By combining natural language processing with fast local SQL execution, it provides a lightweight, privacy-friendly, and developer-friendly solution that simplifies structured data analysis for users of all skill levels.
