A Google Drive trigger initiates the workflow upon new file detection. 2. The system retrieves temporary access and sends the file to a transcription service. 3. Text content is cleaned, saved, and processed to extract key information. 4. An AI agent analyzes the content and generates a representative image. 5. The final output is uploaded to YouTube, followed by automated cleanup of temporary resources.\n\n### Setup steps\n\n- Configure the Google Drive Trigger with appropriate folder permissions.\n- Connect LemonFox credentials for the audio transcription service.\n- Set up Google Gemini credentials for the AI agent and image generation.\n- Configure YouTube API credentials for the final video upload.\n\n### Customization\n\nAdjust the AI prompt in the Gemini node to change the style of the generated imagery or to provide more specific summarization parameters."
