If you're new to OpenAI Realtime or new to n8n or both, this primer gets you comfortable in an afternoon. No jargon. No fluff.
What OpenAI Realtime is
OpenAI Realtime is a voice ai tool. It stores records and events, and exposes an API. n8n talks to that API on your behalf.
What n8n is
n8n is a workflow platform. You wire nodes together to move data and trigger actions across OpenAI Realtime and everything else you use.
Your first workflow
Trigger on a OpenAI Realtime event → transform → write somewhere. That's automation. Really. That's it.
Where to go next
Add a second workflow. Then a third. Automation compounds — three small workflows beat one big one every time.
