  1. 1

    Poll for New Comments

    Add a Schedule Trigger running every 30 minutes, then an HTTP Request to the YouTube commentThreads endpoint for your channel to fetch recent comments.

  2. 2

    Filter Already-Handled Comments

    Add a step that checks each comment ID against a Google Sheet or n8n static data so you never draft a reply twice.

  3. 3

    Draft the Reply With AI

    Add an OpenAI node prompted with your brand voice: Write a warm, concise reply to this YouTube comment. Include the video title for context.

  4. 4

    Send to Slack for Approval

    Add a Slack node posting the original comment and the AI draft with approve/edit buttons so you can post it in one click.

  5. 5

    Activate and Test

    Activate the workflow and leave a test comment on one of your videos. Confirm the AI draft appears in Slack within the next poll cycle.

Frequently asked questions

Can it auto-post approved replies?

Yes. Wire the Slack approval button to an HTTP Request that posts the reply back through the YouTube API's comments insert endpoint.

How do I handle spam comments?

Add an AI classification step that flags spam or abuse and routes those to a separate channel for moderation instead of drafting a reply.
