This n8n template demonstrates how to use AI to fully automate the generation and scheduling of X (formerly Twitter) content based on a specific, predefined persona. Use cases are many: It's perfect for social media marketers looking to streamline content creation, individual experts building a consistent brand voice, or businesses aiming to drive traffic to specific services with a steady stream of relevant content. Good to know The AI model used in this workflow (via OpenRouter) requires an API key and will incur costs based on usage (typically a few cents per generation). The Blotato node used for posting is a third-party community node and requires a separate Blotato account. How it works This workflow is divided into two main processes: Content Generation and Content Posting. 1. Content Generation Process: A Schedule Trigger kicks off the workflow every 4 hours. An AI Agent (LangChain) generates a post based on a detailed prompt defining a persona, purpose, and rules. A Code node refines the AI's output, ensuring the text ends naturally. The generated post is then saved to a Google Sheet with a "Not Posted" status, creating a content queue. 2. Content Posting Process: The workflow retrieves one "Not Posted" item from the Google Sheet. An IF node checks the post's category to determine if an image is required. If an image is needed, it searches for and retrieves a matching image file from a specified Google Drive folder. The Blotato node posts the text (and image, if applicable) to the designated X (Twitter) account. A confirmation email is sent via Gmail to notify stakeholders of the successful post. Finally, the Google Sheet status is updated to "Completed" to prevent duplicate posts. How to use You can test the workflow anytime using the manual trigger. For production, adjust the posting frequency in the "Trigger: Every 4 Hours" node. The quality of the generated content is determined by the prompt. Edit the system message within the "AI: Generate X Post Content" node to customize the persona, purpose, tone of voice, etc. To generate posts with images, you must upload image files to the specified Google Drive folder. The filename must exactly match the post's category name (e.g., Evidence-basedGraph.png). Requirements An OpenRouter account (or another AI service account) for the LLM. A Blotato account for social media posting. A Google account for content management, image storage, and notifications (Sheets, Drive, Gmail). Customising this workflow Expand the workflow to post to other social media platforms supported by Blotato, such as Facebook or LinkedIn. Instead of posting immediately, add a human-in-the-loop approval step by sending the AI-generated draft to Slack or email for review before publishing. Replace the Schedule Trigger with a Webhook Trigger to generate and post relevant content based on external events, such as "when a new blog post is published."
