  1. 1

    Trigger when a new YouTube video goes live

    A YouTube Trigger starts the workflow the moment a new YouTube video goes live.

  2. 2

    Hand it to the AI agent

    An AI Agent node running OpenAI spins out five platform-ready captions. The prompt is pre-written and scoped to this one job so results stay consistent.

  3. 3

    Deliver the captions

    The result is saved to Notion — instantly, no clicks needed.

  4. 4

    Add a safety net (optional)

    Insert an IF/human-approval step before anything is published or emailed, so you stay in control until you trust the output.

Frequently asked questions

Can I trust the AI to get the captions right?

The prompt is tightly scoped to one job and you can add a human-approval step in n8n before anything is sent or published. Start with review-mode for a week, and once you trust the output, switch it to fully automatic.

Does this need n8n Cloud or can I self-host?

Either works. The workflow is a standard n8n export, so you can run it on n8n Cloud or on your own self-hosted instance — you only connect your own app credentials.

How do I import the workflow into n8n?

Download the JSON, then in n8n open a new workflow, choose ⋯ → Import from file, and select it. Every trigger, node and connection appears on the canvas; you just add your credentials and activate it.
