Talk it through.
Keep creating.
Your Mayor connects your voice to Firstmate. Ask for help while you wander the town, and keep the conversation close to the work.
A thought, then a reply.
Hold to talk, release to send. Mayor passes your request to Firstmate and speaks the reply when it is ready.
Hold Control + Option · Or use the in-town talk button
Room for a conversation.
Talk with Mayor through live voice. Requests that need computer work go to the same trusted Firstmate.
Start Live voice · Stop the conversation whenever you like
Mayor needs separate setup in desktop Settings, configured OpenAI voice services, and a trusted Firstmate checkout. Voice-service usage is billed separately; you can use Pet Street and explore Pet Town without enabling Mayor.
Before you move in
A few good
A few good
questions.
Is Pet Town free?
The Mac app and solo browser preview are free. Your coding tool’s usual account and usage charges still apply. Optional Mayor voice uses separately billed voice services.
Do I need to download the 3D world?
Not for Pet Street. The Mac app starts with desktop companions; Settings → App offers the optional Pet Town download. There is no second app to install. Removing the download keeps your saved games.
What is different in the browser preview?
It is a solo preview to try before downloading. Explore the world in a desktop or touch browser without installing the app. Desktop Pet Town is available now; live coding-agent companions and optional Mayor voice need the Mac app. Browser and desktop saves do not transfer automatically.
What does Mayor need?
Mayor uses your configured OpenAI voice services and a Firstmate checkout you explicitly trust. Standard and Live mode use the same Firstmate primary. Voice service usage is billed separately.
Where does my world save?
World changes are stored in the current browser or desktop app. Browser and desktop saves do not transfer automatically.
Can I make my own Pet Street pets?
Import transparent APNG animations in Pet Studio, assign their behaviors, and save a local pet pack.
Which computers support the desktop app?
Pet Town currently provides macOS downloads for Apple Silicon and Intel Macs. The solo town runs in desktop and touch browsers with WebGL graphics support.
Bring the town
home to your Mac.
Start with Pet Street. Download the optional Pet Town 3D world from Settings in the same free app.
