1.1 Workflow description

Title
Summarize YouTube videos and generate thumbnails using AI Agent and deAPI
Workflow name
Summarize YouTube videos and generate thumbnails using AI Agent and deAPI

Who is this for?

  • YouTube creators who want to speed up their post-production workflow
  • Content repurposers who turn videos into written summaries
  • Social media managers handling multiple YouTube channels
  • Anyone who needs quick, AI-generated thumbnails from video content

What problem does this solve?

Watching a full video to write a summary and then designing a matching thumbnail is tedious. This workflow does both automatically — transcribe, summarize, and generate a professional 1280x720 thumbnail — all from a single YouTube URL.

What this workflow does

  1. Takes a YouTube video URL as input
  2. Transcribes the full video using deAPI (Whisper Large V3)
  3. AI Agent analyzes the transcript, writes a concise summary, and uses the deAPI Prompt Booster tool to craft an optimized thumbnail image prompt
  4. Generates a 1280x720 landscape thumbnail using deAPI
  5. Uploads the thumbnail to Google Drive

Setup

Requirements

  • n8n instance (self-hosted or n8n Cloud)
  • deAPI account for video transcription, prompt boosting, and image generation
  • Anthropic account for the AI Agent
  • Google Drive API access for file uploads

Installing the deAPI Node

  • n8n Cloud: Go to SettingsCommunity Nodes and toggle the "Verified Community Nodes" option
  • Self-hosted: Go to SettingsCommunity Nodes and install n8n-nodes-deapi

Configuration

  1. Add your deAPI credentials (API key + webhook secret)
  2. Add your Anthropic credentials (API key)
  3. Add your Google Drive credentials (OAuth2)
  4. Set the target Google Drive folder ID in the Google Drive Upload node
  5. Ensure your n8n instance is on HTTPS

How to customize this workflow

  • Change the AI model: Swap Anthropic for OpenAI, Google Gemini, or any other LLM provider
  • Adjust the prompt style: Modify the AI Agent system message to target different thumbnail aesthetics (minimalist, bold text overlay, cinematic, etc.)
  • Change the output destination: Replace Google Drive with Dropbox, S3, Notion, or email delivery
  • Add a summary output: Insert a Google Docs or Notion node after the AI Agent to save the written summary alongside the thumbnail
  • Process in bulk: Replace the Manual Trigger with a Google Sheets trigger containing a list of YouTube URLs
  • Swap the trigger: Use a Form Trigger to let team members submit YouTube URLs through a web form
  • Other video platforms: The transcription node also supports Twitch VODs, X (Twitter), and Kick URLs

4. Reproducing the Workflow from Scratch

  1. 1. Download the workflow JSON

    Use the JSON export at /data/workflows/13889/13889.json as the source template for this automation.

  2. 2. Import the template into n8n

    Open n8n, import the downloaded JSON, and review each node before activating the workflow.

  3. 3. Configure credentials and variables

    Replace placeholder credentials, API keys, webhook URLs, account IDs, and environment-specific values with your own settings.

  4. 4. Test with sample data

    Run the workflow manually or in a staging workspace, inspect node output, and confirm downstream systems receive the expected data.

  5. 5. Activate and monitor

    Enable the workflow only after testing, then monitor executions, errors, and rate limits during the first production runs.

5. General Notes & Resources

Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.

Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.
