Frequently asked questions

Do I need to know SQL?

No. QueryAI translates your plain-English question into SQL for you, runs it against your uploaded CSV with DuckDB, and shows you both the generated SQL and the results table.

Where is my data stored?

Your uploaded CSV is stored on our server tied to your browser session so you can ask follow-up questions. It is never used to train any model and is not shared with other customers.

What database engine actually runs the query?

DuckDB, an open-source in-process analytical SQL engine. Every query you see the results for was actually executed against your file — nothing is a canned demo.

What if the generated SQL is wrong?

QueryAI always shows you the exact SQL it generated alongside the results, so you can verify it yourself or hand it to an analyst. Only SELECT statements are ever allowed to run — QueryAI cannot modify your data.

What file size / row limits apply?

25MB per CSV on every plan today. Result-row limits and daily question counts scale with your plan — see pricing.
