GrowthDept for ChatGPT: your marketing department as a ChatGPT app

Add GrowthDept to ChatGPT once. Then ask it in a chat what went out this week, what waits for your yes, or start a campaign, without opening another tab.

Add GrowthDept to ChatGPT

A paid ChatGPT plan: Plus, Pro, Business or Enterprise, with Developer mode turned on. On Business or Enterprise, your workspace admin may need to allow it.

The address is https://growthdept.app/mcp. Every step, and how to use a key instead of signing in, is on the setup page.

Three steps

  1. Press Add to ChatGPT on this page. It copies GrowthDept's address and opens ChatGPT's settings.
  2. Under Apps, then Advanced settings, turn on Developer mode. Back in Apps, press Create, name it GrowthDept, paste the address and choose the sign in option.
  3. Sign in with your GrowthDept account and pick the business. In a new chat, press the plus button, choose GrowthDept and ask it something.

What you can ask it

  • "What did my marketing do this week?"
    Reads what went out and where, and what waits for you.
  • "What is waiting for my yes?"
    Lists the drafts waiting for you, with their words.
  • "Launch a campaign for house removals in Lewisham."
    Sets the focus and queues the work. It goes through your approval settings.
  • "Check my website and tell me the first thing to fix."
    Checks your site the way a search engine does.
  • "Where do I show on Google, and what changed since last week?"
    Reads your own Search Console, once Google is connected.
  • "What do people search for when they need what I do in Croydon?"
    Finds the real searches people type, place by place.
  • "How do my App Store and Google Play pages read?"
    Reads your app's store pages and the changes GrowthDept suggests.
  • "Draft a reply to my newest app review."
    Writes a draft. You say yes to it yourself in GrowthDept.

What it cannot do

  • Put anything online itself. What GrowthDept writes goes through your approval settings, which start at asking you first.
  • Say yes to a draft you did not ask it to.
  • Change your own website.
  • Promise a result or a place on Google.

What it costs

The connection is included on every GrowthDept plan, and the 7-day free trial needs no card. Reading costs nothing. When it asks GrowthDept to write or plan, that spends Growth Credits at the same rates as in the app. Your ChatGPT plan is separate. See Pricing.

Questions

Which ChatGPT plans can use GrowthDept?
Paid plans: Plus, Pro, Business and Enterprise. ChatGPT adds an app you bring yourself through Developer mode, under Settings, then Apps, then Advanced settings.
Why does ChatGPT show a warning when I add it?
ChatGPT shows it for every app you add yourself in Developer mode. It says the app is not made by OpenAI, which is true: GrowthDept is made by ForgeAI Studio Ltd. Accept it to carry on.
Is GrowthDept an MCP server?
Yes. GrowthDept's connector is a remote MCP server at https://growthdept.app/mcp, so the same address works in Claude, ChatGPT, Gemini, Cursor, Codex and Claude Code.
Can it post for me?
The assistant cannot put anything online itself. It can launch a campaign, and what GrowthDept writes then goes through your approval settings, which start at asking you first. When you ask it to, it can record your yes or no to a draft.
What does it cost?
The connection is included on every GrowthDept plan, and the 7-day free trial needs no card. Reading costs nothing. When it asks GrowthDept to write or plan, that spends Growth Credits at the same rates as in the app. Your assistant's own plan is separate.
Is GrowthDept made by OpenAI?
No. GrowthDept is made by ForgeAI Studio Ltd, a UK company. It works with ChatGPT as a connector you add yourself, and it is not made or endorsed by OpenAI.
