Agentsql vs Text2SQL.ai

AgentSQL is a web service that turns plain-English questions about connected databases into read-only SQL queries, then returns a chart, table, and plain-English answer. Each response shows the exact SQL, and users can rephrase their question to have the service rewrite and rerun it. Supported connections are Postgres, MySQL, Snowflake, and BigQuery. Connections use least-privilege read-only credentials, can be limited to selected tables, and can be revoked. AgentSQL says it encrypts connections in transit, does not copy database tables or build a shadow warehouse, and does not use database contents, queries, or results to train AI models. It stores query history; Team and Scale also retain result rows. Plans are billed yearly: Starter costs $24 per month, Team $59 per month, Scale $179 per month, and Enterprise $299 per month. Monthly allowances are 600, 1,500, 5,000, and 8,000 questions respectively, with no more than one tenth usable in a day. The service targets founders, operations teams, analysts, and product managers.

Text2SQL.ai converts natural-language requests into SQL and also provides query explanation, fixing, and optimization. Users can supply database tables, columns, and relationships as schema context so generated queries can reflect their database structure. Its Insights view combines a generated query with its results, a chart, and an explanation. Direct connections are supported for MySQL, PostgreSQL, and SQL Server; other databases can use extraction scripts or AI schema parsing. Safe Mode validates generated queries to help guard connected databases against accidental or malicious modifications. The cloud service is available on the web and through an API, with desktop apps for Windows, macOS, and Linux included in Pro subscriptions. The public API supports SQL generation for Pro and higher plans, and requests use plan credits. Pro includes 100 API requests per month, with additional requests listed at $0.05 each. Pricing starts at $29/user/mo, and a free trial is offered without a stated duration. The maker says it stores database schemas and SQL-related chat messages, but not actual database data. For the desktop app, it says credentials stay on the device and only schema names go to AI providers.
