Description

This n8n template demonstrates how to build O’Carla, an advanced all-in-one Discord AI assistant. It intelligently handles natural conversations, professional image generation, and visual file analysis within a single server integration.

Use cases are many: Deploy a smart community manager that remembers past interactions, an on-demand artistic tool for your members, or an AI that can “read” and explain uploaded documents and images!

Good to know

• API Costs: Each interaction costs vary depending on the model used (Gemini vs. OpenRouter). Check your provider’s dashboard for updated pricing.
• Infrastructure: This workflow requires a separate Discord bot script (e.g., Node.js) to forward events to the n8n Webhook. It is recommended to host the bot using PM2 for 24/7 uptime.

How it works

1. Webhook Trigger: Receives incoming data (text and attachments) from your Discord bot.
2. Intent Routing: The workflow uses conditional logic to detect if the user wants an image (via keyword gambar:), a vision analysis (via attachments), or a standard chat.
3. Multi-Model Intelligence:
   • Gemini 2.5: Powers rapid and high-quality general chat reasoning.
   • Llama 3.2 Vision (via OpenRouter): Specifically used to describe and analyze images or text-based files.
   • Flux (via Pollinations): Uses a specialized AI Agent to refine prompts and generate professional-grade images.
4. Contextual Memory: A 50-message buffer window ensures O’Carla maintains the context of your conversation based on your Discord User ID.
5. Clean UI Output: Generated image links are automatically shortened via TinyURL to keep the Discord chat interface tidy.

How to use

1. Connect your Google Gemini and OpenRouter API keys in the respective nodes.
2. Replace the Webhook URL in your bot script with this workflow’s Production Webhook URL.
3. Type gambar: [your prompt] in Discord to generate images.
4. Upload an image or file to Discord to trigger the AI Vision analysis.

Requirements

• n8n instance (Self-hosted or Cloud).
• Google Gemini API Key.
• OpenRouter API Key.
• Discord Bot Token and hosting environment.

Customising this workflow

O’Carla is highly flexible. You can change her personality by modifying the System Message in the Agent nodes, adjust the memory window length, or swap the LLM models to specialized ones like Claude 3.5 or GPT-4o.
