AI2SQL

What is AI2SQL?

AI2SQL is an AI SQL generator for people who need database answers without hand-writing every query. You describe what you want in plain language and it returns SQL for MySQL, PostgreSQL, SQL Server, Oracle, SQLite, Snowflake, BigQuery and other engines. The same workspace explains existing queries, fixes syntax errors, formats code and, on higher plans, optimizes slow statements. Pro and Team users can connect a live database so generation is schema-aware and queries run read-only, and an MCP server lets Claude, ChatGPT, Cursor and VS Code write SQL through AI2SQL. A desktop app for Windows and Mac is included from Pro. Prompts can be written in several languages, including English, Spanish, French, German and Japanese. Pricing starts at $9 per month for Start, $19 for Pro and $39 for Team, each with a 7-day trial, plus a one-time $29 Lifetime plan.

Use cases

• Generate SQL from a plain-English question
• Explain an unfamiliar query line by line
• Fix SQL syntax errors
• Optimize slow queries
• Run read-only queries on a connected database
• Convert JSON or ER diagrams to SQL
• Write SQL from inside Claude or Cursor

Who it's for

• Developers
• Data analysts
• Non-technical team members
• Students learning SQL

Why use AI2SQL

• You can get working SQL without knowing the syntax, which helps analysts and non-technical teammates who just need an answer.
• Pro and Team connect to your real schema, so queries reference actual table and column names instead of guesses.
• The MCP server brings AI2SQL into the assistants and editors you already use for coding.
• Explain and fix tools double as a learning aid for people picking up SQL.
• A one-time Lifetime plan avoids a recurring subscription for lighter users.
