๐ŸŽฏ Description\n\nThis n8n workflow automates the process of transforming PDF documents into engaging, SEO-friendly WordPress blog posts. It incorporates AI-powered text analysis, automatic image generation, and a human review step to ensure quality before publishing.\n\n## ๐Ÿš€ How It Works\n\n### ๐Ÿ—‚๏ธ PDF Upload & Text Extraction \n- Users upload a PDF document through a form trigger. \n- The workflow extracts text from the uploaded file, ensuring compatibility with supported formats.\n\n### ๐Ÿค– AI-Powered Blog Post Generation \n- The extracted text is analyzed by an AI model (GPT-based) to create a structured blog post. \n- The AI generates: \n - A captivating SEO-friendly title. \n - Well-formatted HTML content, including an introduction, chapters with subheadings, and a conclusion.\n\n### ๐ŸŽจ Image Creation & Integration \n- An image is generated using **Pollinations.ai** based on the blog post title. \n- The vibrant image is uploaded to WordPress and set as the featured image for the post.\n\n### ๐Ÿ“ WordPress Draft Creation \n- A draft blog post is created on WordPress with the AI-generated title, content, and featured image. \n\n### โœ… Human-in-the-Loop Approval \n- The draft content is sent via Gmail to a reviewer for manual approval. \n- If approved, the post is published on WordPress. If not, an error message is sent for troubleshooting.\n\n### ๐Ÿ“ข Multi-Channel Notifications \n- Once published, notifications are sent via Gmail and Telegram to relevant stakeholders. \n\n## ๐Ÿ”ง Setup Steps\n\n### ๐Ÿ”‘ Configure API Credentials \n1. Set up API connections for: \n - OpenAI (for AI content generation). \n - WordPress (for post creation and media uploads). \n - Gmail (for sending approval emails). \n - Telegram (for notifications). \n\n### โš™๏ธ Customize Workflow Parameters \n2. Adjust the AI prompt to match your desired blog structure and tone. \n3. Modify the image generation parameters to align with your branding needs.\n\n### ๐Ÿงช Test & Deploy \n3. Test the workflow with sample PDFs to ensure: \n - Accurate text extraction. \n - Proper formatting of generated content. \n - Seamless approval and publishing processes. \n\n\nThis workflow streamlines content creation while maintaining quality control through human oversight, making it an ideal solution for efficient blog management! ๐ŸŽ‰\n" }, "typeVersion": 1 }, { "id": "8ea57c7f-256b-4a89-b62f-3a6390fec719", "name": "Sticky Note6", "type": "n8n-nodes-base.stickyNote", "position": [ 360, -960 ], "parameters": { "width": 2520, "height": 1700, "content": "# ๐Ÿ“„โœจ Easy WordPress Content Creation from PDF Document + Human in the Loop with Gmail Approval" }, "typeVersion": 1 }, { "id": "8cf6bd65-b025-45df-b556-a5fac970aa9b", "name": "Get Blog Post", "type": "n8n-nodes-base.code", "position": [ 2080, -760 ], "parameters": { "jsCode": "// Get the HTML content from the previous node\nconst htmlContent = $input.first().json.text;\n\n// Use regex to extract the text between the first h1 tags\nconst titleRegex = /
