Your Syzygy account

Mach Studio works without an account. Local models, your own API keys, and your own harness subscriptions never need a sign-in. A Syzygy account adds the cloud side: hosted models with credits, hosted integrations, and the Pro features.

What an account gives you

• Cloud models in the composer, paid for with credits on your account.
• Hosted integrations for Slack, Gmail, Notion, and more, connected without managing your own keys.
• The skills marketplace, for searching and installing shared skills.
• Pro features: included inference credits, automations, remote control, and cloud environments. See Plans and billing.

Sign in

1. Click Sign in with Syzygy at the bottom of the sidebar, or open Settings → General and click Sign in with Syzygy under Account.
2. Your browser opens. Sign in and choose the workspace you want Mach Studio to use.
3. Mach Studio picks up the sign-in and shows your name at the bottom of the sidebar.

If the app does not come back on its own, use the authorization link shown in Mach Studio. You can click Cancel sign-in at any time and start again.

Choosing a workspace

Your workspace is chosen in the browser during sign-in. Cloud models and credits follow that workspace. To use a different workspace, sign out and sign in again. If Mach Studio tells you that you do not have access to the selected workspace, ask a workspace admin to add you.

Manage Account

Click your name at the bottom of the sidebar to open the account menu:

• Manage Account opens your Syzygy dashboard in the browser, where you manage your plan, credits, and billing.
• Send Feedback sends a note to the team.
• Sign out signs out on this computer only.

Settings → General also has an Open account settings button that opens the same dashboard.

Signing out

Signing out removes the account from this computer. Your chats, local models, and settings stay exactly where they are, and anything local keeps working.
