Discord AI Chatbot with GPT-4o-mini & Redis Memory Persistence

This n8n workflow powers a Discord AI chatbot that monitors a specified channel for new messages, generates intelligent replies via GPT-4o-mini, and posts them as threaded responses under the original message. A Python Discord bot script acts as a bridge, forwarding messages to an n8n webhook for processing. Redis ensures conversation history persistence, allowing context-aware interactions even after restarts.

The workflow excels in handling community discussions, customer support, or AI-driven engagement by maintaining seamless, coherent conversations. It runs stably on an Ubuntu server managed by PM2, combining n8n's automation with external services for robust performance.

Key benefits include time-saving automation of repetitive responses, enhanced user experience through memory retention, and scalability for high-traffic servers. Ideal use cases: Discord communities, support bots, educational Q&A, or entertainment chat features. Prerequisites: Discord bot token, Redis instance, and optional Pella.app hosting.

Setup involves creating a Discord bot in the Developer Portal, enabling intents, configuring n8n credentials for OpenAI and Redis, deploying the Python bridge, and activating the webhook.
