Frequently asked questions
Is SQLAI free?
New customers get a 7-day free trial, and you can cancel at any time. See pricing.
Can I use my own schema without connecting a database?
Yes. Import your schema as DDL, JSON or CSV, or start without a schema. Adding one helps SQLAI tailor its answers to your tables and columns. Add your database.
Which databases can I connect directly?
Live connections are available for PostgreSQL, MySQL, SQL Server, Oracle and MongoDB, though connection features vary by engine. For many other engines, you can import a schema without a connection. See the database catalog.
Do you have a demo?
Yes. You can explore the app without signing in and see how it works with test data. See the demo app.
Does SQLAI run queries against my database?
Never automatically. You review the SQL and decide whether to run it. With a supported SQL database connection, you can choose to run a read-only query in the app; otherwise, you can use your own database client.
Is AI-generated SQL always correct?
No. Although we offer some of the most accurate SQL tools, AI can make mistakes, even with schema context. Review the SQL, check that it returns the intended results and test performance before using it in production.
