Connects Muse to your GPT Business workspace. Muse can read your existing business data, calculate quotes and invoices, and prepare drafts for you to review before anything is sent. Sign-in with your GPT Business account is required.

Example request: "Calculate a quote for 40 hours of consulting at my standard rate and draft the email to send it to the client."

How to connect: GPT Business is not in Muse's Connectors list yet, and it needs you to sign in with your GPT Business account. Apps that need this kind of sign-in usually cannot be used from a Muse chat yet. Follow it here and we will tell you when it reaches Muse.
