# Preview, plan and code

URL: https://getflowing.ai/docs/ai/build-tab

The Build tab, on plans with GetFlowing's agent: chat with the agent, open the preview, follow the plan, edit code yourself and look at your data.

On plans with GetFlowing's agent, each app's **Build** tab is where you work with the agent. The chat is on the left, and the views are beside it: **Preview** and **Plan**, and, with **Show code** on, **Code** and **Data**. **Show code** is remembered for you.

## Preview

**Preview** is where you open your deployed app: **Open app** opens it in a new tab.

On Scale and Enterprise, **Instant preview** shows your changes as you make them, before anything is deployed.

## Plan

While a new app is being planned, **Plan** opens the plan for you to check and approve. After that, it shows the build's progress. See [Planning a new app](https://getflowing.ai/docs/ai/planning).

## Code

**Code** is a built-in editor, with the chat beside it. Change a file and choose **Save**: the change is committed to your repository's default branch, with the message "Update ‹file› from the dashboard editor". **Discard changes** throws away what you have not saved.

Saving does not deploy. Press **Deploy** when you want the change live. If the app deploys from a branch other than the default branch, the saved change is not on that branch until you merge it there.

- A file can be up to 1 MB.
- If the branch is protected, the editor cannot save to it. Ask the agent for the change instead, and it opens a pull request.
- Only an owner or admin can save a change to a CI workflow file.

On Scale and Enterprise, **VS Code in the browser** opens the same code in a full VS Code editor.

## Data

For an app with a managed database, **Data** lets you browse its **Tables**, run one read-only `SELECT` at a time in the **SQL console**, and **Export CSV**. Nothing here can change your data. See [Databases](https://getflowing.ai/docs/configure/databases).
