Is there a free AI SQL or text-to-SQL tool, and how does iDBQuery compare?

There are genuinely free ways to get SQL from a question: open-source text-to-SQL libraries and models, and general chatbots that will draft a query. They're useful for one-off help, especially if you can already read and run SQL. The trade-off is that 'free' usually means you supply everything around the query.

• Free tools stop at the query. You still connect the data, run the SQL safely, check correctness, join across sources, and build any interface — all yourself.
• No citations. A drafted query gives you a result with no trail back to the source rows, so verification is manual.
• Single-source by default. Most free options target one database at a time, not a question spanning systems.
• What iDBQuery adds. It writes and runs the SQL, returns the answer with every figure cited to its source row, joins databases, spreadsheets, PDFs and APIs into one live model, and enforces read-only, governed access — deployable in the cloud, your VPC or air-gapped.

If you just need occasional SQL help and can run it yourself, a free tool may be enough. If you want dependable, cited, cross-source answers for a team without building the surrounding system, iDBQuery is a complete product — and you can try it before committing.
