AI2sql is an AI SQL assistant that generates, explains, fixes and optimizes SQL queries on your real database schema, for developers and analysts.
About
AI2sql is an AI-powered SQL query builder and generator that works against a user's actual database schema rather than generic example tables. The problem it addresses is familiar to anyone who writes SQL: translating a question in plain English into a correct query with the right table names, joins and dialect-specific syntax, or debugging and speeding up queries written by someone else. AI2sql generates that SQL from the live schema of a connected database, then runs it against a read-only connection so the user can verify the results immediately.
The product is made by AI2sql and is available as a web app, a desktop application for Windows and Mac, and an MCP server that plugs into tools such as Claude, ChatGPT and Cursor. Users connect a database with read-only credentials, AI2sql builds a semantic layer from the schema (tables, joins and business terms), and generated queries use the real names and dialect of that database. Beyond generation, the same tooling explains, fixes, optimizes and formats existing queries whether they were written by hand or produced by AI.
Key Features
Pricing & Fees
- Pricing: A Free plan allows 3 SQL queries per day on a demo database. Paid plans are Start at $9/month, Pro at $19/month and Team at $39/month (25% cheaper billed annually), plus a one-time Lifetime plan for $29 with 500 AI queries per month.
- Free trial: Every paid plan begins with a 7-day trial at $0; a credit card is required, and cancelling before the trial ends means no charge.
- Plan limits: Start includes 100 queries per month with a basic AI model; Pro adds unlimited queries, an advanced model, database connections, MCP access and the desktop app; Team adds 5 users, a shared query library and role-based access control.
- Security: Database credentials are encrypted in transit and at rest, queries are read-only, and the vendor states that queries and schemas are never sold or used to train models.
- Local option: A desktop Connector app runs next to the database so credentials never leave the user's machine.
Who It's For
AI2sql is aimed at software developers who write SQL regularly and want generation, fixing and optimization grounded in their production schema, as well as data analysts who need reports quickly without hand-writing every join. It also suits SQL learners and students, since seeing a question mapped to SELECT, JOIN and GROUP BY is a practical way to learn. Teams running AI agents benefit from the governed, read-only gateway with audit logs and per-agent keys, while database administrators get read-only enforcement and encrypted credentials as a safety boundary.
