What it does

Three things, done well

💬

Plain English questions

"Show me the top 10 customers by revenue last quarter" becomes a JOIN query with date filters, GROUP BY, and LIMIT. Instantly.

🔒

Schema-grounded SQL

The AI reads your real table names and column names before generating. It never invents columns that don't exist.

▶️

Execute and see results

The SQL runs against your live database and shows results on canvas. Edit if needed, then copy to your BI tool or notebook.

How it works

Up and running in 60 seconds

1

Connect your database

Enter Snowflake or BigQuery credentials. The connector reads your schema — table names, column names, row counts.

2

Ask a question

Type your question in the Input node: "which regions had declining sales last month?" The LLM writes dialect-correct SQL using your real schema.

3

Review and run

SQL appears in the SQL Runner node. Review it, edit if needed, hit Execute. Results stream back to the canvas.

Your data answers questions now

No SQL training. No waiting for a data analyst. Ask, get SQL, see results — in under 60 seconds.
