FAQ
Five honest answers
What is Duct?
An open-source AI agent that connects your product, marketing and revenue tools, answers questions across them, proposes changes and applies them when you approve. It runs as a desktop app on macOS, Windows and Linux.
Is it free?
Yes. The core is MIT licensed and stays that way. You pay your model provider directly, or sign in with the ChatGPT plan you already have. A hosted team plan comes later; the core stays open.
Does it change my accounts without asking?
No. Reporting works with read-only access. A change is proposed with what it touches, and applied only when you press Apply. Destructive changes are flagged; anything over a guardrail is blocked until you look.
Which tools does it connect to?
Google Ads, Meta Ads, Apple Search Ads, OpenAI Ads, GA4, Search Console, Tag Manager, Mixpanel, Microsoft Clarity, GrowthBook, Stripe and RevenueCat. Every connection is OAuth; nothing is exported by hand.
Where do my keys and data live?
Model keys stay in your operating system's keychain and travel with a request only while a job runs. Connector authorisations are stored encrypted by the hosted API. The desktop app is a thin shell over that API; a self-host build runs everything on your own machine. Why it's called Duct is on the about page.
