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.

Its core is the Hex Agent, a conversational interface that plans a query, reasons over your organisation's context and returns an answer with the charts, tables and code that produced it. Because every answer is grounded in a semantic model and the underlying warehouse tables, users can inspect the SQL, check assumptions and trust the number before acting on it. The agent is reachable from the web workspace, from Slack, and from developer tools such as Claude and Codex via CLI and integrations. Underneath the conversational layer sits a genuine notebook and app-building environment. Analysts write SQL, Python and R in the same project, chain cells into reproducible pipelines, and then turn selected cells into polished, parameterised data apps and dashboards that stakeholders can interact with. Hex 4.0 pushes this further with generative dashboards, AI app building and a Context Engine that keeps the company's definitions, metrics and semantics in one place. A Context Studio surfaces where the agent lacked grounding, and an Evals framework lets teams run graded test suites against the agent to measure accuracy over time. That governance angle is what separates Hex from raw chat-with-your-data tools. Instead of an unsearchable answer in a side panel, you get a shareable, versionable artefact with lineage, plus a feedback loop that compounds context quality. It is used by data teams at a wide range of companies for self-serve exploration, executive reporting, embedded dashboards and operational analytics, with free, paid and enterprise tiers covering individuals through to regulated organisations needing SSO and advanced security. **Pricing & Plans:** Freemium with a free tier to get started, paid plans for growing teams, and enterprise pricing (quoted on request) that adds governance, SSO and advanced security. A free trial is available for paid tiers. - **Conversational Hex Agent:** Ask a question in plain language and get a reasoned answer with the SQL, charts and tables behind it, available in the Hex workspace, in Slack and from developer tools. - **Notebooks and app builder:** Write SQL, Python and R side by side in one project, then turn cells into interactive, parameterised data apps and dashboards without a separate BI authoring tool. - **Context Engine and Context Studio:** Centralise metrics, semantics and corporate definitions so answers stay consistent, and see exactly where the agent lacked grounding so you can fix it. - **Evals for agent accuracy:** Run graded, rubric-based test suites against the agent to measure answer quality and catch regressions as your data and context evolve. - **Generative dashboards and governance:** Produce dashboards from natural language, embed them where teams work, and manage access with enterprise-grade permissions and security. **Strengths:** Unifies exploration, notebooks, dashboards and app building so teams stop paying for four overlapping tools; Answers are grounded in a semantic model and warehouse tables, and stay inspectable rather than opaque; Slack, CLI and developer-tool integrations meet users where they already work; Context Studio and Evals turn context quality into something measurable and improvable **Limitations:** The full value depends on having a reasonably well-modelled warehouse, so it is heavier to adopt than a simple chat tool; The notebook-plus-agent surface is feature-rich enough to need onboarding for non-technical users; Governance and advanced security features are reserved for higher-priced and enterprise plans [Profile (Markdown)](https://openaitools.app/tool/hex-tech.md) ## Frequently Asked Questions ### How do AI2SQL and Hex compare in monthly traffic?
