Overview

AI2SQL is an AI-powered SQL query builder and database assistant that turns natural-language prompts into SQL and related query workflows. The product is built around dialect-aware generation, so the output is matched to the target database engine rather than written as generic SQL.

The product can be used in the browser, through live database connectors, from an MCP endpoint for AI agents, or through the desktop app. Across those modes, it focuses on writing, explaining, optimizing, formatting, and fixing SQL while keeping access governed and read-only by default.

Core capabilities

Text-to-SQL generation

Generate dialect-aware SQL from natural-language prompts and schema context, then run it in the browser or through connected workflows.

SQL toolbox

Generate, explain, optimize, format, and fix SQL in the browser with the classic SQL toolbox.

Live database connectors

Connect to supported databases to ground generation in real table and column names instead of relying on generic SQL patterns.

MCP server for agents

Use the MCP endpoint with tools such as run_query, describe_schema, and list_connections for agent-driven database workflows.

Desktop app

Install the local desktop app for SQL generation, execution, and history on macOS and Windows with zero cloud dependency.

Workflow extras

Use SQL file upload, formula generation, ER diagrams, and chat support on paid plans, according to the pricing page.

Common use cases

Natural-language query building
Write SQL from a plain-English request when you know the business question but do not want to handcraft the query from scratch.
SQL review and cleanup
Check, explain, format, or optimize existing SQL before running it or sharing it with teammates.
Agent-based database access
Ground an AI agent in a live schema so it can describe the database, choose the right tables, and execute a read-only query.
Local desktop SQL workflow
Work locally on a personal machine when credentials should stay on-device and query execution should not depend on the cloud.
Multi-database environments
Support teams that need multiple database engines by generating dialect-aware SQL for systems such as PostgreSQL, MySQL, SQL Server, Snowflake, BigQuery, MongoDB, and Oracle.
