What is Retool?

Try Retool

Retool helps teams generate and build internal apps on top of their data, with an AI-assisted workflow designed for business use cases. With AppGen, you can generate apps on your data in your cloud and refine them into secure, team-ready tools. You can also connect apps to APIs and databases, add workflows, and build analytics and operational UIs.

What is Retool used for?

Retool is used to build internal apps such as app experiences, admin-style tools, and dashboards using your existing data and services. You can also connect UIs to APIs and build workflows for day-to-day operational processes.

How does AppGen work for generating apps from my data?

AppGen generates apps built for business on your data, in your cloud, and secure by default. After generation, you can keep refining what was generated so it fits your specific environment and use case.

Yes. Retool lets you connect to REST API endpoints and build UIs on top of your data sources, including databases and external apps. You can use these connections to create dashboards, frontends, and internal tools.

How low-code (or no-code) is Retool for app building?

Retool is a low-code platform that uses AI-assisted generation to speed up early building. You can start from generated output and then customize and refine the app as you go.

What kinds of AI capabilities can I add to Retool apps?

Retool supports AI-assisted app experiences using AI primitives, agents, and AI-powered workflows. You can also connect to AI providers so your apps can respond intelligently alongside your data.
