# Welcome old

Glad to have you on board!

## What is Jet Admin?

Jet Admin is an **app builder** that allows you to create **Client Portals**, **Business Apps**, and **Internal Tools** with your **existing data**, whether it's from databases, APIs, or Storages. You can build apps such as `Onboarding apps`, `Admin Panels`, `Vendor portals`, `CRMs`, and much more quickly and without code.

## Building a Business App?

This **2-min video** will explain what Jet Admin is and what you can build with it:

2. [**Sync and Blend your data**](/user-guide/synced-tables.md): Create a single source of truth (SSOT) that syncs to your multiple data sources (Stripe, Hubspot, Salesforce, ...).
3. [**Build App Interfaces**:](/classic-app-builder/design-and-structure/components.md) Drag and drop UI components (Tables, Forms, Charts, Details Images) onto Layouts (Modals, Columns, Tavs) and connect them to your data sources.
4. [**Customize your app**](/classic-app-builder/component-designer.md): Design pixel-perfect components or use 50+ ready-to-use components from Marketplace.
5. [**Automate your workflow**](/workflow/overview.md): Create multi-sequence Automation with over 30+ automation blocks and trigger them by Webhook or Schedule jobs every minute, hour, day, or month.
6. [**Publish and share your app**](/classic-app-builder/design-and-structure/core-concept/sharing-your-app.md)

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.jetadmin.io/welcome-old.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
