THE HONEST COMPARISON
Why not just ask ChatGPT?
Fair question, and the honest answer is that for a one-off query on a schema you can paste into a chat box, a general assistant is fine. The gap opens the moment the database is real: dozens of tables, a dialect that matters, and a query whose result someone will act on.
| CHATGPT | AI2SQL | |
|---|---|---|
| Writes SQL from a plain-English description Both do this well. It is not the difference. | ✓ yes | ✓ yes |
| Knows your tables and columns without pasting them in AI2SQL reads the live schema, so joins and column names are yours, not a textbook's. | — no | ✓ yes |
| Emits the right dialect for your database A chat window guesses unless you keep reminding it. AI2SQL targets the connection you picked. | ~ partial | ✓ yes |
| Runs the query and hands back rows Generation is half the job. The other half is finding out whether the answer is right. | — no | ✓ yes |
| Refuses writes, DROP and DDL by default Read-only is enforced before the statement reaches your database, not requested politely in a prompt. | — no | ✓ yes |
| Explains, optimizes and fixes a query you already have Both can. AI2SQL does it against the real schema and the real plan. | ✓ yes | ✓ yes |
| Lets your own AI agent query the database A governed MCP endpoint — Cursor, Claude and any MCP client speak it already. | — no | ✓ yes |
| Keeps a query library the whole team can reuse | — no | ✓ yes |
✓ yes · ~ partial · — no
Try it on your own schema →HOW IT WORKS
From raw schema to trusted answers
01
Connect
Point AI2SQL at your Postgres, MySQL, SQL Server, Snowflake, BigQuery, MongoDB or Oracle. Read-only credentials, encrypted at rest.
02
Ground
We build a semantic layer from your schema — tables, joins and business terms — so your agent generates SQL that's correct on YOUR data, not a textbook's.
03
Answer
Your agent calls run_query over MCP or REST. Governed, read-only SQL executes and the answer comes back — audited and metered per query.
WHO USES IT
Built for the query in front of you
Data analyst
You know the question, not the join.
Ask in English, get a query that matches your real column names, then run it and read the rows without leaving the page.
Backend developer
You have a query that works and a query that is slow.
Paste it in. Get an explanation of what it does, an optimized version, and a fix when the dialect fights you.
Data engineer
Six databases, six dialects, one afternoon.
One place that speaks PostgreSQL, MySQL, SQL Server, Oracle, Snowflake, BigQuery, Redshift, MongoDB, SQLite and Firebird.
AI agents
Your agent needs data, not a copy of your credentials.
A governed MCP endpoint any MCP client speaks. Read-only by default, every query logged, keys scoped per agent.
Learning SQL
You want the answer and the reason.
Every generated query comes with an explanation, so the next one you write yourself.
THE WORKFLOW
One place for the whole query, start to finish
Generate
Describe the result you want.
Plain English in, SQL out — using your real table and column names, in the dialect of the database you picked.
Explain
Inherited a query nobody remembers writing?
Get a plain-language walkthrough of what it does, clause by clause, so you can trust it before you run it.
Optimize
It works, but it takes 40 seconds.
Get a rewritten version and the reasoning — the join that should have been a filter, the index that is missing.
Fix
Paste the query that will not run.
Syntax errors, dialect mismatches and wrong column names, corrected with an explanation of what broke.
Format
Make it readable before it goes in the PR.
Consistent casing, indentation and line breaks in one pass.
Run
Then find out whether the answer is right.
Execute against a live read-only connection and read the rows without leaving the page.
CONNECTORS
Ten databases, one syntax to learn
Connect with read-only credentials and AI2SQL uses your live schema to write queries in that database's dialect.

AI2SQL GATEWAY
Safe database access for AI agents
Your team already uses AI agents. The gateway lets them query your database through one governed MCP endpoint — read-only, rate-limited and fully audited.
- ✓ Read-only enforced at the gateway — writes never reach your database
- ✓ Every query logged with the key that ran it; revoke any key in one click
- ✓ Works with Claude Code, Claude Desktop, Cursor and ChatGPT via MCP
1 write attempt blocked — nothing reached your data. Every call logged.
CUSTOMER SUCCESS STORIES
Real Experiences with AI2sql
We are working on a project where our users can type a question into a test box and it generate data for them, AI2SQL has proven that this would be a viable solution for our customers.
I am a developer in visual foxpro 9.0 with SQL server. I'm trying to get you to help me generate a script for the database tables. So far it has been easy to operate.
I just started learning data analytics over a month now and I was given assignments. What would have taken me hours to figure out was done in 10 mins by this awesome AI2sql. I will always come back here. you guys are the best.
I'm an analyst, and this has been a great way to cram for sql assignments. Needs to be worked with some prior knowledge, but for most part, its great.
AI2sql is a powerful tool that can help anyone to generate SQL queries without the need for specialized knowledge or training. It is especially helpful for those who are new to working with databases.
This tool has helped me fix several critical errors in our SQL scripts that have been effecting several areas of our company. This tool is well worth the monthly cost.

FAQ
Frequently asked questions
Is there a free trial, and do you need my card? + −
Every plan starts with a 3-day free trial. $0 is charged today, but a card is required to start it, and you can cancel in one click from your account before the trial ends — you pay nothing.
Is my database safe? + −
Connections are read-only by default. sqlGuard classifies every statement before it reaches your database and blocks INSERT, UPDATE, DELETE, DROP and other DDL, multi-statement input, and functions that read server files. Credentials are encrypted, every query is logged, and you can revoke a key at any time.
Can it read my own schema? + −
Yes — that is the point. Connect a database and AI2SQL uses your real tables, columns and relationships when it writes SQL, so joins and names match your schema instead of a generic example.
Which databases are supported? + −
PostgreSQL, MySQL, SQL Server, Oracle, Snowflake, BigQuery, Amazon Redshift, MongoDB, SQLite and Firebird.
How is this different from letting ChatGPT write SQL? + −
For a single query on a schema you can paste into a chat box, it is not very different. The gap is everything that needs the live database: knowing your tables without being told, emitting the right dialect, running the query and returning rows, refusing writes, and exposing the same thing to your own AI agent.
Is there an API, and can my AI agent use it? + −
Yes. There is a REST API, and a governed MCP endpoint that any MCP-compatible client speaks — Cursor, Claude, ChatGPT in developer mode, or your own agent. Keys are scoped per agent and every call is metered and logged.
Does it work offline or on the desktop? + −
There is a desktop app for Windows and macOS on the Pro plan, which is also how you reach a database that only listens on localhost or an internal hostname. Query generation itself needs a connection to our API.
