Generate YouTube Content Ideas from Video Analysis with Dumpling AI and GPT-4o

Who's it for

This template is perfect for YouTube creators, content marketers, and social media managers who want to turn existing videos into fresh, high-performing content ideas—automatically. It’s ideal if you want to save time brainstorming and focus on publishing videos that your audience actually wants.

What it does

This workflow watches a Google Sheet for new YouTube video links. For each new video, it fetches the transcript and top comments using Dumpling AI, then sends that data along with the original search topic to GPT-4o.

GPT-4o returns 3–5 new content ideas based on: What was discussed in the video What people are searching for What viewers are saying in the comments

Each idea is saved to another Google Sheet and also sent to your email.
