Generate, explain, optimize and fix — all four tools are dialect-aware, so Presto / Trino output uses Presto / Trino syntax rather than generic SQL.

Frequently asked questions

Presto or Trino dialect? +

Trino (the active fork) by default — which also runs on most modern Presto deployments; legacy function names are avoided.

Can it query across data sources? +

Yes — that's Trino's point; AI2SQL generates cross-catalog joins when you name tables from different sources.

Is it Athena-compatible? +

Amazon Athena is Trino-based — generated queries run on Athena with the same syntax.
