This guide explains how to quickly generate and modify business applications using ToolJet. You can create an app from scratch with a single prompt or enhance an existing app with AI-powered assistance.

## Creating Application
To create an application, follow these steps:

1. **Enter a prompt** – Describe the business application you want to build in the prompt input on the dashboard.

2. **Check Specs File** – After submitting your prompt, a new app will be created, and you’ll be taken to the App Builder, where a specs files will be generated including list of features, navigation, etc.

3. **Design Layout** - Once you accept the specs then a Design Layout will be generated, you can either accept it or modify it in the visual builder.
    <img className="screenshot-full img-full" style={{ marginTop: '15px' }} src="/img/tooljet-ai/generate-app/ui.png" alt="tooljet generate apps" />
4. **Select Data Source** - After approving the design layout, you need to select the data source, ToolJet AI Builder currently supports two data sources - PostgreSQL and MongoDB.

5. **Database Schema** - After selecting the data source you can approve or modify the database schema.

6. **App Generation** – Once you confirm all the requirements then a fully fucntional app will be generated.

### Modifying Application

You can modify any application in ToolJet with AI assistance, whether it's a newly created app or an existing one. You can update components and queries within your application with just a prompt.

### Limitations

ToolJet AI supports generating queries with [RunJS](/docs/data-sources/run-js) and the following data sources:

- [Postgres](/docs/data-sources/postgresql/)
- [MongoDB](/docs/data-sources/mongodb)

## Generating Code

ToolJet lets you generate JavaScript, Python, or SQL code directly using AI.

1. Click the AI icon in the query panel to ppen the AI code generator. <br/>

2. Enter a prompt describing the logic or query you want to build. <br/>
    <img className="screenshot-full img-m" style={{ marginTop: '15px' }} src="/img/tooljet-ai/gen-code/prompt.png" alt="tooljet generate apps" />
3. Check the generated code and either insert it directly or click Regenerate to try a different version. <br/>
