Why Traditional Analytics Cloud Tools Harm Your Data Privacy
Traditional BI tools and modern AI chatbots usually require uploading your sensitive business data to their remote servers. This introduces security compliance headaches and latency.
Writing complex SQL queries or building pivot tables manually in Excel takes hours, taking you away from actually understanding your data.
Most solutions put your privacy at risk or demand technical expertise.

You ask questions in simple, natural language.
- 3

100% Client-Side
Your CSV data never leaves your device. We use DuckDB WASM to query directly within your browser.

No SQL experience needed. Bring your own LLM API key (like OpenAI or Anthropic) and our integration generates the exact query.
Instant Visualizations
Automatically renders beautiful, interactive dynamic charts alongside your queried data tables using Vega-Lite.
Auto-Healing Queries
If the AI makes a mistake, the app feeds the error back and self-corrects the query automatically.

Custom Column Context
Edit column descriptions manually to give the AI better context about exactly what your data means.

No data engineering required.
Upload your data securely
Drop your CSV file into the browser. It stays locally on your machine—never touching a backend real server.
Ask a natural question
Type 'What were the top 5 products by revenue last month?' The AI generates the complex SQL for you. Or use the manual SQL mode to run everything on your browser.
