Post images from Google Drive to Discord using Gemini Gemini AI

🎯 What This Does

This workflow automatically monitors a specific Google Drive folder for new images. When you drop a file in, it uses Google's Gemini AI to analyze the image, generate an creative title, and write a high-engagement description. It then posts the image and text to a Discord channel and organizes your Google Drive by renaming the file and moving it to a "Processed" folder.

🔄 How It Works

• Watch: The workflow detects when a new image file is uploaded to a specific Google Drive folder.
• Analyze: It downloads the image and sends it to a Google Gemini AI Agent to identify the "hook" and generate technical/marketing copy.
• Format: The AI returns a structured title, description, and a new optimized filename.
• Publish: The workflow posts the image and the AI-generated caption directly to your Discord channel as a new thread.
• Organize: Finally, it renames the original file in Google Drive and moves it to a separate "Processed" folder to keep your workspace clean.

🚀 Setup Requirements

• n8n Version: Latest stable release recommended.
• Google Cloud Console Project: With Google Drive API enabled.
• Google Gemini API Key: For the AI generation.
• Discord Application: A Bot Token with permissions to send messages/create threads in your server.
• Estimated Setup Time: ~15 minutes.

Set up steps

1. Configure Google Drive Credentials:

• Set up a project in Google Cloud Console.
• Enable the Google Drive API.
• Create OAuth 2.0 credentials and add them to the Google Drive Trigger and Google Drive nodes in n8n.

1. Prepare Drive Folders:

• Create a folder in Google Drive for Input (where you drop files). Copy the Folder ID from the URL.
• Create a folder for Processed files. Copy this Folder ID as well.
• Paste the Input Folder ID into the Google Drive Trigger node.
• Update the processed_folder_id value in the "Get File & Set Channel" (Set) node.

1. Configure AI Agent:

• Get your API Key from Google AI Studio.
• Add a new credential for Google PaLM API in the Chat Model node.

1. Setup Discord Bot:

• Go to the Discord Developer Portal and create a new Application/Bot.
• Copy the Bot Token.
• Invite the bot to your server.
• Enable Developer Mode in your Discord User Settings to right-click a channel and "Copy Channel ID".
• Update the channel_id in the "Get File & Set Channel" node.
• Open the "Post To Discord Channel" (HTTP Request) node. Under Authentication, select "Predefined Credential Type" -> "Discord Bot API" and paste your token.

1. Test the Workflow:

• Click "Test Workflow" in n8n.
• Upload an image to your Google Drive Input folder.
• Watch the execution! Check Discord for the new post and Drive to see the file move.

Nodes Used

• Google Drive Trigger: Watches for new content.
• Google Drive: Downloads, Updates (Renames), and Moves files.
• AI Agent (LangChain): Orchestrates the analysis.
• Google Gemini Chat Model: Generates the creative text.
• Structured Output Parser: Ensures the AI replies in usable JSON.
• HTTP Request: custom API call to Discord for advanced thread creation.
• Set: Manages variables and folder IDs.

Customization Guide
