**No need to write SQL anymore. Just ask questions in plain English and get your answers (with the SQL behind them).** Link in Comments

I work in BI/data, and many questions from business teams sound simple: * Which branches have the highest NPA? * How did disbursements trend this year? * What's the average loan size by product type? But answering them usually requires someone to write SQL, validate the logic, and explain the results. So I built **Ask Your Data**, an AI-powered Text-to-SQL app that lets you ask questions about a synthetic retail loan portfolio of 1 Million Rows. ## How it works You ask a question in plain English, and the app: Generates a PostgreSQL query. Validates and executes the query. Returns the answer in simple language. Displays a chart, result table, and the exact SQL generated, so you can verify the answer instead of blindly trusting the AI. 🛠️ **Tech stack:** Next.js, FastAPI, PostgreSQL (Neon), and GPT-4.1-mini. *All data used in the app is synthetic.* --- ## What I learned The biggest challenge wasn't getting the model to write SQL. It was helping it understand business terminology and return the right answer. A query can be syntactically correct and still be completely wrong from a business perspective. **Try to break it.** That's the kind of feedback that will help me improve the app. *Live demo and source code links are in the first comment.*
