LLM Social Media Reach: Optimized Content for Twitter, Discord & LinkedIn

This workflow automates AI-driven content optimization for Twitter, Discord, and LinkedIn, enhancing viral engagement. Key nodes include Chat Trigger (initiates user input), Condition (validates input length), Chain LLM (optimizes content using OpenRouter’s LLaMA-4), Output Parser Structured (formats output), Split Out (separates platform-specific content), Switch (routes content), Twitter (posts to Twitter/X), Discord (posts via webhook), LinkedIn (posts to profiles), and Set (handles success/error responses). The workflow uses the OpenRouter API for AI processing and platform-specific APIs for publishing.\n\nSetup requirements and configuration: Install n8n from n8n.io (self-hosted) or sign up at cloud.n8n.io. Obtain API credentials: OpenRouter key from openrouter.ai, Twitter OAuth2 from developer.twitter.com, Discord webhook from discord.com/developers, and LinkedIn OAuth2 from developer.linkedin.com. Import the JSON workflow in n8n. Configure Chat Trigger with a webhook URL, Twitter, Discord, and LinkedIn nodes with respective credentials in ‘Credentials.’ Set the Discord webhook URL in the Discord node. Add environment variables OPENROUTER_API_KEY, TWITTER_ACCESS_TOKEN, DISCORD_WEBHOOK_URL, LINKEDIN_ACCESS_TOKEN. Ensure internet access for API calls. In n8n settings, configure the Chat Trigger webhook URL, ensuring public accessibility (e.g., via ngrok for local setups). Verify platform credentials are correctly linked to avoid authentication errors.\n\nTesting and deployment steps: Activate the workflow to generate the Chat Trigger webhook URL. Test by sending a message like “Promote our new product launch” via the chat interface. Verify platform-specific outputs in Twitter, Discord, and LinkedIn, ensuring content adheres to character limits and engagement best practices. Check the success response for confirmation (e.g., “Content successfully optimized and published to Twitter”). Test invalid inputs (e.g., messages under 10 characters) to trigger the error response (“Invalid input: Message must be at least 10 characters long”). Monitor logs for errors like ‘Invalid OpenRouter key,’ ‘Twitter API rate limit exceeded,’ or ‘Discord webhook not found.’ Validate posts on each platform for correct formatting and language consistency with the input.
