AI will generate initial content based on your input.\n3. The AI extracts suitable keywords from the generated content.\n4. The keywords are sent to Pexels API to search for relevant royalty-free images.\n5. AI creates the final polished content that matches the selected image.\n6. The result is displayed as a formatted HTML template with content and image combined.\n\n### How to Set Up\n1. Get a OpenAI API key from [https://platform.openai.com](https://platform.openai.com).\n2. Get a free Pexels API key from [https://www.pexels.com/api](https://www.pexels.com/api). You can make up to 200 requests per hour.\n3. Insert your OpenAI API key in the \"Create Content with AI\" and \"Create Suitable Content\" nodes.\n4. Insert your Pexels API key in the \"Pexels Image Search\" node in the Authorization header.\n\n### Customize\n1. **Optimize token usage**: If you are an advanced user, use the floating node in the \"Alternative way to optimize token usage\" section to process everything in one prompt and minimize API costs. If you use this option, update the expressions in the \"Pexels Image Search\" node and \"Create Suitable Content Including Image\" node to reference the extracted contents and keywords from the JS node.\n2. If you want deeper content analysis, change the model to a more advanced one, for example GPT-4.1, GPT-5.1, or GPT-5.2."
