SQLAI.ai
SQLAI.ai turns plain-language questions into production-ready SQL across 28 database engines including PostgreSQL, MySQL, Snowflake, BigQuery, and Oracle. Six specialized generators handle text-to-SQL, query optimization, syntax validation, plain-language explanation, formatting, and dialect conversion. You can import a schema file or connect a read-only database so the AI writes queries with table and column context instead of guessing.
Single-purpose text-to-SQL tools stop at generation. SQLAI.ai adds an optimizer that rewrites slow queries with index-aware suggestions, a validator that catches cross-engine syntax errors before deploy, and a diff view comparing original and AI-improved SQL side by side. Database rules let teams enforce quoting conventions and row limits per datasource, and schema autosuggest surfaces table names while you type prompts.
Data analysts, product engineers, and database administrators at startups and enterprises use SQLAI.ai to skip the back-and-forth with data teams. The platform reports trust from more than 150,000 professionals. Paid plans start at $4 per month for 50 queries, scale to 3,000 queries on Pro at $20 per month, and include a 7-day free trial with no credit card required.
