Adding the AI Node in n8n

In n8n, the AI integration is usually called "OpenAI" or "Anthropic" (depending on which provider you choose). The flow is similar:

1. Add a new node.
2. Search for "OpenAI" or "Anthropic".
3. Click "Create new credential" and authenticate with your API key.
4. Configure the node:
5. Model: Pick the one you want.
6. System prompt: The instruction set.
7. Messages: The actual input (this varies slightly by provider; sometimes it's a structured message object).
8. Test with sample data.
9. Map upstream data once it works.

n8n's interface is slightly more technical than Make's, but the concepts are identical. You're sending a prompt + data to an LLM and getting back text.
