Auto-generate SEO content from trends with GPT-4o, FAL AI & multi-storage

Who's it for Content creators, SEO specialists, and marketing teams who want to automatically generate SEO-optimized content based on trending topics—complete with AI-generated images, optional videos, and ready-to-publish HTML.

How it works / What it does 1. Webhook receives a request with use case and video preferences. 2. Get Trends XLSX downloads a spreadsheet (created by the Social Media Trends workflow) from SharePoint. 3. Select Topic from Trends randomly picks one trending topic from the spreadsheet. 4. AI Agent (GPT-4o) generates bilingual newsletter content about the selected trend. 5. Get Newsletter Template fetches your HTML template; Build Newsletter injects the AI content. 6. Optional creative assets: • Pollinations AI → generates a 1080 × 1350 image. • FAL AI → creates video from the image + Lyria2 audio → merged via FFmpeg. 7. Gmail Approval sends the draft for review; continues only on approval. 8. Upload all files (HTML + JPG + video URL) to your chosen storage provider.

How to set up 1. Import the template into n8n (cloud or self-hosted). 2. Create credentials: OpenAI, Microsoft 365 (SharePoint), Gmail, and FAL AI. 3. Upload your HTML newsletter template to SharePoint (see yellow sticky note for required placeholders). 4. Ensure you have a trends spreadsheet (from the Social Media Trends workflow) in your SharePoint folder. 5. Update Configuration Settings with your ENV variables. 6. Activate the workflow and POST to the webhook: { "text": "usecase: blog post, includevideo: true" }.
