"content": "The **AI Blog Creator with Gemini, Replicate Image, Supabase Publishing & Slack** is a fully automated content generation and publishing workflow designed for modern marketing and SaaS teams.\nIt automatically fetches the latest industry trends, generates SEO-optimized blogs using AI, creates a relevant featured image, publishes the post to your CMS (e.g., Supabase or custom API), and notifies your team via Slack all on a daily schedule.\n\nThis workflow connects multiple services NewsAPI, Google Gemini, Replicate, Supabase, and Slack into one intelligent content pipeline that runs hands-free once set up.\n\n---\n\n### **✨ Features**\n\n* 📰 **Fetch Trending Topics** — pulls the latest news or updates from your selected industry (via NewsAPI).\n* 🤖 **AI Topic Generation** — Gemini suggests trending blog topics relevant to AI, SaaS, and Automation.\n* 📝 **AI Blog Authoring** — Gemini then writes a full 1200-1500 word SEO-optimized article in Markdown.\n* 🧹 **Smart JSON Cleaner** — A resilient code node parses Gemini’s output and ensures clean, structured data.\n* 🖼️ **Auto-Generated Image** — Replicate’s Ideogram model creates a blog cover image based on the content prompt.\n* 🌐 **Automatic Publishing** — Posts are automatically published to your Supabase or custom backend.\n* 💬 **Slack Notification** — Notifies your team with blog details and live URL.\n* ⏰ **Fully Scheduled** — Runs automatically every day at your preferred time (default 10 AM IST).\n\n---\n\n### **⚙️ Workflow Structure**\n\n| Step | Node | Purpose |\n| ---- | ----------------------------------- | ----------------------------------------------- |\n| 1 | **Schedule Trigger** | Runs daily at 10 AM |\n| 2 | **Fetch Industry Trends (NewsAPI)** | Retrieves trending articles |\n| 3 | **Message a model (Gemini)** | Generates trending topic ideas |\n| 4 | **Message a model1 (Gemini)** | Writes full SEO blog content |\n| 5 | **Code in JavaScript** | Cleans, validates, and normalizes Gemini output |\n| 6 | **HTTP Request (Replicate)** | Generates an image using Ideogram |\n| 7 | **HTTP Request1** | Retrieves generated image URL |\n| 8 | **Wait + If** | Polls until image generation succeeds |\n| 9 | **Edit Fields** | Assembles blog fields into final JSON |\n| 10 | **Publish to Supabase** | Posts to your CMS |\n| 11 | **Slack Notification** | Sends message to your Slack channel |\n\n---\n\n### **🔧 Setup Instructions**\n\n1. **Import the Workflow** in n8n and enable it.\n2. Create the following credentials:\n\n * **NewsAPI (Query Auth)** — from [https://newsapi.org](https://newsapi.org)\n * **Google Gemini (PaLM API)** — use your Gemini API key\n * **Replicate (Bearer Auth)** — API key from [https://replicate.com/account](https://replicate.com/account)\n * **Supabase (Header Auth)** — endpoint to your `/functions/v1/blog-api` (set your key in header)\n * **Slack API** — create a Slack App token with `chat:write` permission\n3. Edit the **NewsAPI URL** query parameter to match your industry (e.g., `q=AI automation SaaS`).\n4. Update the **Supabase publish URL** to your project endpoint if needed.\n5. Adjust the **Slack Channel** name under “Slack Notification”.\n6. (Optional) Change the **Schedule Trigger** time as per your timezone.\n\n---\n\n### **💡 Notes & Tips**\n\n* The **Code in JavaScript** node is robust against malformed or extra text in Gemini output — it sanitizes Markdown and reconstructs clean JSON safely.\n* You can replace Supabase with any CMS or Webhook endpoint by editing the “Publish to Supabase” node.\n* The Replicate model used is `ideogram-ai/ideogram-v3-turbo` — you can swap it with Stable Diffusion or another model for different aesthetics.\n* Use the `slug` field in your blog URLs for SEO-friendly links.\n* Test with one manual execution before activating scheduled runs.\n* If Slack notification fails, verify the token scopes and channel permissions.\n\n"
