Create your first application

This walkthrough takes you from a signed-in workspace to a running preview.

Before you begin

Sign in with GitHub. GitHub is used for your DeplAI identity. Building an application from a description does not require connecting a repository.

DeplAI Agent is included with an active Starter or Pro organization tier, whether purchased or granted by the DeplAI owner. Open Account → Billing if the workspace asks you to upgrade.

1. Open DeplAI Agent

From the workspace, open Services → DeplAI Agent (/dashboard/agents).

Create a conversation or open an existing one. Each conversation holds one product thread: the original request, later changes, builds, and saved application versions.

2. Describe the application

Use Build mode. Write what you want as a product, not as a technology list.

Example:

> Build a project management app for a small design agency. I need projects, tasks, due dates, team members, status filters and a dashboard.

Say who will use it, what they should accomplish, what information it manages, and any roles or design direction. See Writing a good request.

3. Answer any follow-up questions

DeplAI may ask a short set of product questions before it builds—for example how people sign in, or who can administer the app. Choose an answer or keep DeplAI’s recommendation. You can refine the product later with Modify.

4. Watch the build

After you submit, DeplAI understands the request, creates the application, and starts a preview when the application can run. Activity updates appear as the work proceeds. You do not need to wait for every check before you look at a preview if one is already available.

Typical activity includes understanding the application, building it, starting the preview, checking workflows, and improving issues.

5. Open the preview

Open the Preview panel as soon as it becomes available. Use the application as a first-time user would: navigate, submit forms, and try important actions.

While you review, DeplAI may still be checking journeys and presentation and may save improved versions. Preview available and Ready explains the difference.

6. Review files, checks, and history

Use the inspector while the conversation is open:

Select an earlier build in the conversation to inspect that version’s preview, files, and checks.

7. Request changes or download source

When a build is Ready, use Modify to change the existing application in natural language. The previous version remains available.

If a build needs attention, use Retry for another attempt from the same product request, or Ask DeplAI to fix to continue from that unsuccessful build.

When you want the source outside DeplAI, use Download code on the Files panel. The archive is produced from a saved application version.

What success looks like

You can open a working preview, understand what DeplAI checked, request a change without starting over, and download source for a version you care about.
