AI2sql vs Text2SQL
AI2sql and Text2SQL.ai are the two direct rivals in natural-language-to-SQL. AI2sql: free limited plan, Start $9 per month, Pro $19 per month, Team $39 per month (ai2sql.io, per the current record), with schema-aware generation, explain/optimize/fix tooling, live database connectors on higher tiers and an MCP gateway so AI agents get governed read-only database access. Text2SQL.ai is a schema-aware SQL generator with a public API and a desktop app whose privacy benefit is that credentials stay local; however, no dollar price was asserted on the official homepage reviewed on 2026-11-01 (a Pricing Plans heading with no amounts), so the old draft's Pro about $19-20 and Team about $40 annual figures are dropped. Pick AI2sql for schema-grounded generation plus agent-ready access; pick Text2SQL for the desktop privacy model and straightforward API use, after checking its current pricing. We did not hands-on test either product, so no quality winner is declared.

| Limitations | The free plan covers only a few queries a day on a demo database, and a payment card is required to start the paid trial. Query limits per tier are real (e.g. 100/month on Start), so heavy users must | ['No dollar prices were shown in the homepage copy retrieved, despite a Pricing Plans heading', 'Generated SQL still needs human review before running on real data', 'The desktop privacy benefit depends on the local setup working as described'] |
Use the same input
An analyst who knows the business but not SQL needs to pull weekly metrics from Postgres without waiting on engineering.
What a successful result must preserve
The tool must generate correct dialect-specific SQL from plain language, handle the real schema, and keep data handling acceptable to security.
