Overview
Dex is an AI-powered data querying tool that lets anyone on your team get answers from your company's database using plain English — no SQL knowledge required. Trusted by Y Combinator founders, Dex connects to a growing mix of data sources, including PostgreSQL, Snowflake, BigQuery, MySQL, spreadsheets, BI tools, and other connected sources documented by the team and translates natural language questions into optimized SQL queries, returning instant insights with charts, tables, and contextual explanations.
Traditional AI data analysis workflows require filing engineering tickets, waiting for dashboards to be built, and hoping the data is still relevant by the time you get it. Dex eliminates that bottleneck entirely. By integrating with Slack, it places data answers directly inside the tools your team already uses every day.
Privacy is built-in by design: Dex never stores your actual data, never uses it to train AI models, and processes all queries end-to-end with AES-256 encryption. For fast-moving startup teams and operators who need answers in seconds — not weeks — Dex turns your database into a conversational interface.

Multi-Database Support — Connects to PostgreSQL, Snowflake, BigQuery, MySQL, spreadsheets, BI tools, and other connected data sources, letting you query across your data stack from a single interface.
Slack Integration — Answers data questions directly inside Slack, keeping insights in your daily workflow without switching between tools or waiting for reports.
Zero Data Storage — Query results are processed in real-time and never stored or saved, and your data is never used to train AI models, making Dex safe for sensitive business data.

- Companies handling sensitive data that require strict no-storage and no-AI-training guarantees
FAQ
What databases does Dex support?
Dex publicly documents support for PostgreSQL, Snowflake, BigQuery, and MySQL, along with other connected data sources such as spreadsheets and selected tools referenced by the team. The team is actively adding new integrations — you can contact hello@dexdata.ai if your database isn't on the list.
Does Dex store my data?
No. Dex never stores your actual database records. Query results are processed in real-time and immediately discarded. Your data is also never used to train or fine-tune AI models.
How secure is the connection to my database?
Dex says credentials are encrypted using industry-standard practices and are not exposed to the AI layer. Dex publishes a full privacy policy at dexdata.ai/privacy.
What are credits, and how fast do I use them?
Credits are consumed per query you run. The Free plan includes 500 credits/month, which is enough for light exploration. Heavy users querying data multiple times a day will likely need the Starter or Professional plan.
Is there a free trial for paid plans?
Dex offers a Free plan with 500 credits and 1 database connection — no credit card required. You can upgrade to a paid plan at any time from the pricing page.
Can I use Dex in Slack?
Yes. Dex has a native Slack integration that lets you ask data questions and receive answers directly inside Slack channels, without opening a separate app or dashboard.
Does Dex work for non-technical users?
Dex is explicitly designed for non-technical users — founders, operators, and business stakeholders who need data insights but don't know SQL. The interface accepts plain English questions and handles all query generation automatically.
How is Dex different from traditional BI tools like Tableau or Looker?
Traditional AI data visualization and BI tools require data teams to pre-build dashboards and define metrics before end users can explore data. Dex lets anyone ask ad-hoc questions in plain English and get answers immediately, without relying on dashboard-first workflows, although teams still need connected data sources and schema context. It's designed for speed and accessibility, not for replacing structured reporting infrastructure.
What happens if Dex can't answer my question?
If a question is ambiguous, users should validate Dex's output by reviewing the generated query and returned results.
Can I export query results?
Yes. Query results can be exported as CSV or PNG files, making it easy to share findings in reports, slide decks, or emails.
