What is AI2sql?
AI2SQL is an AI-powered SQL assistant that works directly on your real database schema. Instead of guessing column names or dialects, it reads your live schema so the SQL it generates matches your actual tables, joins, and business terms. You can connect databases like Postgres, MySQL, SQL Server, Snowflake, BigQuery, MongoDB, and Oracle.
You start by connecting your database with read-only credentials. AI2SQL builds a semantic layer from your schema, then you describe what you want in plain English. It generates SQL, runs it, and returns rows. You can also paste existing queries to get explanations, optimizations, or fixes for errors.
It suits data analysts, backend developers, data engineers, and AI agents. A governed MCP endpoint lets tools like Cursor or Claude query your database safely. Every query is logged and read-only by default, so it is safe for team use. A 7-day free trial is available with no charge today.

What to check before you rely on AI2sql
- Check that your database credentials are read-only before connecting, since AI2sql enforces read-only access but you must set up permissions.
- Verify the 7-day trial's end date and cancellation process, as the website lists the trial but not renewal or post-trial pricing.
- Confirm your database platform is supported, since AI2sql lists Postgres, MySQL, SQL Server, Snowflake, BigQuery, MongoDB, and Oracle.
- Check whether AI2sql exports query results or integrates with your BI tools, as the website does not state export formats or integrations.

AI2sql FAQ
How does AI2SQL know my database schema?
AI2SQL connects to your database with read-only credentials and builds a semantic layer from your actual tables, columns, and joins. This means generated SQL uses your real names, not generic examples.
Is AI2SQL safe to use on my production database?
Yes, it enforces read-only by default and refuses writes, DROP, and DDL statements before they reach your database. Every query is logged and metered, so actions are auditable.
