How do you use Antigravity with an existing app?

In the Antigravity desktop app, open a copy of your project. If the project uses Git to track file changes, the Review pane lets you see what the agent changed, file by file. Google also offers a terminal client and extensions for supported editors.

For an individual account, use a personal Google account in a supported country or territory. Google lists an age minimum of 18. For work accounts, check your organization’s eligibility and which app or editor it supports.

The folder is where local tools work. The account also uses online models. Review what code you can share and which file or command actions need your approval before opening a project.

What would you review before keeping an edit?

On paper, sketch an appointment card with the wrong button label. The button says “Buy now” and should say “Book a time.” The button should still open the same booking form.

List the visible change
Write the old and new labels. Note where the button should lead so the task has a clear stopping point.
Inspect the proposed lines
A change to the label fits the task. A change to the booking form destination or how appointments are saved needs a separate explanation and review.
Check both outcomes
If you try this later in the desktop app, first verify that the open folder is a disposable copy with no live accounts, secrets or deployments. Open a copy that tracks changes with Git. Read the changed lines and use a local preview to check the label and destination. Keep the exercise on paper if you cannot confirm that setup.

Can Antigravity keep working after your laptop sleeps?

Remote Agents can run independently on Google’s computers. Google is rolling them out to eligible personal Google AI Pro and Ultra accounts. A remote session uses the repositories or files you attach to its remote project.

Remote Control is a separate option for reaching a session running on your own computer. For that to keep working, your computer needs to stay powered on and connected.

Do you need a paid plan to start?

Google offers a free individual option with a weekly usage limit. Pro and Ultra have higher limits and can use purchased credits after the included allowance runs out.

Check the overage setting if you have credits. You can choose to wait for your included allowance to refresh instead of automatically using credits.
