An n8n account, plus your own Google Drive, Google Sheets, Slack and Telegram accounts, and a key for OpenAI. You connect your own accounts after importing it; none are included. What starts it? It starts on an event in a connected app. Does it use AI? Yes. It calls OpenAI. Model calls are billed by the provider, not by n8n. How long does it take to set up? Plan an afternoon. 16 steps is enough that you should read each one before running it. How do I import it? Copy the workflow, open a new workflow in n8n and paste. The steps appear on the canvas, ready for your own accounts. **Before you run it** Nothing here has been tested by us. It is somebody's working automation, read and described from its own steps. Treat the connections it wants as a list of accounts it will touch, and read the 16 steps before you point it at anything that matters. ## Run it in n8n - **Create your n8n account** Free to start. n8n is where the workflow runs.
