Google is bringing its Antigravity coding agent into the Gemini Mac app. The integration lets eligible users move from discussing an idea to having an agent work on code in the background.
According to Google’s 13 October release notes, users can select Antigravity at the top of the Mac app, review a plan and receive a notification when the work is ready. Access is in English for eligible adult accounts in supported regions.
Get the Mac app ready
Start with Google’s official download and sign in to your account. Google’s Mac app guidance lists macOS Sequoia 15 or later, at least 8GB of memory and an internet connection among its requirements.
If the integration is missing, check for an app update and confirm account eligibility. Work accounts may also depend on administrator settings.
Choose a small first project
Our recommendation is a local prototype with a clear purpose. A simple content planner, unit converter or reading-list organiser gives you something concrete to inspect without beginning with payments or customer accounts.
Describe the result before asking for code. For example: create a weekly article planner with fields for headline, category, deadline and status. Specify that sample data should be fictional and ask the agent to explain how to run the prototype.
Review the proposed plan and remove unnecessary features before the build begins.
Check the result yourself
Try the main actions, submit an empty form and open the interface at a narrow window size. Ask for an explanation of any external services or ongoing costs.
An agent finishing its task is a starting point for your review. Before sharing the project publicly, make sure it works for the person who will actually use it.
Write a brief the agent can build against
For the article-planner example, describe the person using it and the actions they need. A solo publisher might need to add an idea, change its status and filter the list by deadline. That is a more workable first brief than asking for an entire publishing platform.
Ask the agent to explain where information will be stored and whether it survives closing the app. Decide whether the prototype should work only on your own computer or eventually be shared. Those choices affect what needs to be built and tested.
You can also specify what is outside the first version. Leaving out payments, multiple user roles and external integrations makes it easier to inspect the core planner before adding complexity.
Use an acceptance checklist
Before testing, write down what success looks like. Can you create an article entry, edit its deadline, mark it complete and find it again? What should happen if the headline is blank or the date is invalid?
Ask for the result in language you can understand. If the agent says a test passed, inspect the corresponding behaviour yourself. Save a copy of a working version before requesting a substantial redesign.
Try the interface using realistic sample entries, including a long headline and several articles scheduled for the same day. These examples often reveal issues that a nearly empty demonstration does not.
What to ask before sharing the app
Request a list of external services, required accounts and possible ongoing charges. Ask what the prototype cannot yet do and what would need attention before other people use it.
Keep private material out of a demonstration. A working local prototype can help you decide whether an idea is worthwhile, but sharing it publicly adds separate questions about access, data storage and maintenance. Resolve those before inviting customers or collaborators to depend on it.
