The problem

Your data is there.
The answers aren't.

Most people have data but can't use it — because getting answers requires skills most people don't have.

📊
Excel is overwhelming
Pivot tables, VLOOKUP, complex formulas — getting a simple answer takes hours of work you don't have time for.
🗄️
SQL is a barrier
Databases are powerful but require technical knowledge. Most business users can't write a single SQL query.
💸
BI tools are expensive
Enterprise tools like Tableau or Power BI cost thousands per year and take weeks to set up properly.
How it works

Three steps.
That's all.

No setup, no training, no technical knowledge needed. Just upload and ask.

1
Upload your file
Drag and drop your CSV or Excel file. Or type your data directly into the built-in spreadsheet editor.
2
Ask a question
Type your question in plain German or English. No SQL, no formulas, no technical jargon required.
3
Get your answer
QueryAI generates the SQL, runs it instantly, and shows you the result as a clear chart or number.
