## AI2SQL

AI2SQL is an AI SQL query builder aimed at engineers, analysts and learners who work with databases every day. Instead of guessing at table names, you connect a read-only account and the tool builds a semantic layer from your actual schema, so the joins, columns and dialect match the database you picked. Supported engines include PostgreSQL, MySQL, SQL Server, Oracle, Snowflake, BigQuery, Redshift, MongoDB, SQLite and Firebird.

The workflow covers the whole life of a query. You describe the result you want in English (or another language) and get SQL back; you can paste a query you inherited and get a clause-by-clause explanation, ask for a rewrite with reasoning when something is slow, have broken SQL repaired with an account of what went wrong, and reformat anything before it hits a pull request. Finally you run it against a live read-only connection and read the returned rows without leaving the page.

Beyond the web app, AI2SQL ships an MCP server so clients such as Claude, ChatGPT in developer mode and Cursor can call your database from the chat window, a desktop Connector for Windows and macOS that reaches localhost or internal hosts, and a gateway that gives a team's agents one governed, audited, metered endpoint. Safety features include read-only credentials by default and a sqlGuard layer that blocks writes, DDL and multi-statement input. A free plan and a 7-day trial on paid plans lower the entry cost; the vendor requires a card to start the trial.

**Pricing & Plans:** Freemium model. A free plan starts you off with a demo database; paid plans include a 7-day free trial that requires a card but charges nothing up front, with cancellation in one click. Higher tiers add the desktop Connector and more usage. Check the site for current prices.

- **Text to SQL on your schema:** Describe the result you want in plain English or another language and get SQL written with your real table and column names in the dialect of your chosen database.
- **Explain, Fix, Optimize and Format:** Paste any query — generated or hand-written — to get a clause-by-clause explanation, corrections with reasoning, performance rewrites and clean formatting.
- **Run read-only against live data:** Execute queries against a connected read-only connection and inspect the returned rows and timing directly in the interface.
- **MCP and REST for AI agents:** Expose your database to Claude, ChatGPT in developer mode, Cursor or your own agent through a governed MCP endpoint and a REST API with per-agent keys.
- **Broad database connector set:** Works with PostgreSQL, MySQL, SQL Server, Oracle, Snowflake, BigQuery, Amazon Redshift, MongoDB, SQLite and Firebird.

**Strengths:** Generates SQL from your live schema instead of a generic example, so names and joins actually match your data; Combines generation, explanation, debugging, optimization and execution in one workspace; Read-only credentials and a sqlGuard layer that blocks writes and DDL reduce the blast radius of mistakes; MCP and REST endpoints let the same connection power Claude, Cursor, ChatGPT or a custom agent

**Limitations:** The 7-day trial still asks for a card up front even though no money is charged today; Query generation depends on a connection to the vendor's API, so it is not a fully offline tool

## Postgres Sandbox

Postgres Sandbox, available at postgres.new, takes an idea that sounds unlikely and makes it work: a real PostgreSQL database running entirely inside your browser. It is built on PGlite, a full build of PostgreSQL compiled to WebAssembly, so there is nothing to install and no server to configure. The moment you start writing SQL, a new database is created for you automatically.

Around that core it adds a set of tools for getting things done quickly. An AI assistant helps turn natural-language requests into SQL and to reason about queries, which is valuable when you are sketching a schema or exploring unfamiliar data. You can import CSV files and query them immediately, generate charts from results, and draw ER diagrams to see how tables relate.

Because the engine is genuine Postgres, the SQL semantics match what you would get on a real server, which makes the sandbox a natural place to prototype schemas, test a tricky query, teach SQL, or experiment with semantic search and RAG-style retrieval. It is best understood as a fast, disposable workspace rather than persistent production infrastructure — data lives in the browser rather than on a managed database.

**Pricing & Plans:** Free. Postgres Sandbox runs in the browser at no cost — there is no install, no account requirement mentioned and no paid tier advertised. Just open the page and a PostgreSQL database is created as you start writing SQL.

- **Instant in-browser Postgres:** A new PostgreSQL database is created automatically in your browser via PGlite — no server, no installation, no configuration.
- **AI SQL generation:** An AI assistant helps generate and reason about SQL from natural-language prompts, lowering the barrier for schema and query work.
- **CSV import:** Load CSV data and start querying it directly, which makes the sandbox handy for quick analysis and data exploration.
- **Charts and ER diagrams:** Turn query results into charts and draw ER diagrams to visualise table relationships within the same workspace.
- **Semantic search and RAG:** Explore RAG and semantic-search style workflows against your data, using the sandbox to prototype AI data features.
- **Real Postgres semantics:** Because it is real PostgreSQL, SQL you write here behaves like SQL you write on a server, so results transfer.

**Strengths:** Runs real PostgreSQL with no install or server setup; AI assistance lowers the learning curve for SQL; CSV import, charts, ER diagrams and semantic search in one place; Genuinely free and instant to try in the browser

**Limitations:** Data lives in the browser session, so it is not a persistent production database; Persistent storage depends on browser/IndexedDB and can be cleared; Not a substitute for a managed Postgres server for real applications; AI-generated SQL should still be reviewed before running
