Automate YouTube Content Analysis with n8n & Google Gemini AI

What this workflow does

This workflow uses n8n and Google Gemini AI to get information from any YouTube video fast. It solves the problem of spending many hours manually watching videos and taking notes. The result is a quick report with summaries, transcripts, or social clip suggestions sent by email and saved to Google Drive.

It pulls video data, reads the audience type, and writes detailed text outputs. This makes video analysis easier and faster without losing quality.

Who should use this workflow

Marketers, content creators, and teams who watch YouTube videos to get key points and highlights. They want to save time and avoid mistakes from manual note-taking.

People needing fast, readable summaries or transcripts from videos will find this useful.

• Google YouTube Data API: Fetches video metadata like title and stats.


• Google Generative Language API (Google Gemini AI): Creates audience details and text summaries.


• Google Drive: Stores the text output files.


• Gmail API: Sends email with the analysis result.

Inputs and processing steps

The workflow input requires two things: a YouTube video ID and a prompt type like summary or transcript.

It then does the following steps:

• Builds a YouTube API URL to fetch video metadata.


• Requests detailed video info using YouTube Data API.


• Generates an AI prompt about video audience from the metadata.


• Sends this prompt to Google Gemini AI to get audience analysis.


• Merges YouTube info and AI audience metadata.


• Prepares multiple text prompts for different analysis types.


• Selects the prompt matching user input prompt type.


• Requests the final video information output from Google Gemini AI using the selected prompt.


• Converts AI text output from markdown to HTML.


• Saves the HTML content as a text file on Google Drive.


• Sends the report email with HTML formatting to a specified address.


• Returns HTML output and thumbnail to the user via a web form.

Outputs and results

The final outputs of this workflow are:

• Readable AI-generated summaries, transcripts, or clips with timestamps.


• Saved text files in Google Drive for easy access anytime.


• Email reports for quick sharing with team or clients.


• Web form display for instant user feedback.



You get well-structured video insights in minutes instead of hours.

Common edge cases and failures

• Empty video ID: The form must always have a video ID to avoid breaking the workflow.


• API errors 401 or 403: Check Google API Key validity and permissions.


• Malformed AI response: Ensure prompts are correct and quota limits are not exceeded.


• Google Drive permission issues: Confirm correct folder access.

Customization ideas

• Change text tone or style by adjusting prompts in the Compose Prompts node.


• Add new prompt types like quote highlights or deep analysis in the prompt XML structure.


• Save output files to custom Google Drive folders by changing folder IDs.


• Send emails to different recipients by changing the address in the Gmail node.


• Add more YouTube metadata like captions by extending the HTTP request parameters.
