"content": "# LinkedIn Post Generator with Viral Content Vector Database\n\n## Overview\nAI-powered n8n workflow that creates viral LinkedIn posts by learning from successful content. Features two modules: (1) Telegram-based scraper that builds a vector database of viral LinkedIn posts, and (2) Web form that generates optimized posts using multi-agent AI with RAG (Retrieval-Augmented Generation) from your curated viral content library.\n\n**Key Capabilities:**\n- Scrapes LinkedIn post content via Telegram bot\n- Stores posts in Supabase vector database with OpenAI embeddings\n- 3-agent system analyzes hooks, structures outlines, and generates posts\n- RAG integration retrieves similar viral posts for pattern matching\n- Auto-publishes to LinkedIn or provides formatted output\n\n---\n\n# How It Works\n\n## Module 1: Viral Post Collection (Telegram Bot)\n\n**Step 1: URL Validation**\n- User sends LinkedIn post URL to Telegram bot\n- Workflow validates URL contains \"linkedin.com\"\n- Shows typing indicator for better UX\n\n**Step 2: Content Scraping**\n- HTTP request fetches post HTML\n- CSS selector extracts main commentary: `[data-test-id=\"main-feed-activity-card__commentary\"]`\n- Handles scraping failures with error messages\n\n**Step 3: Vector Storage**\n- Converts post text to OpenAI embeddings (text-embedding-ada-002)\n- Stores in Supabase `linkedin_post` table with vector indexing\n- Sends success confirmation via Telegram\n\n## Module 2: AI Post Generation (Web Form)\n\n**Stage 1: Hook Analysis Agent**\n- **Input**: User-provided hook text\n- **Process**: AI extracts topic, niche/industry, emotional tone, and 3-5 key points\n- **Output**: Structured JSON with analyzed elements\n- **Models**: GPT-4o-mini or Gemini 2.5-flash (dual fallback)\n\n**Stage 2: Post Structure Agent**\n- **Input**: Analyzed hook data\n- **Process**: Creates 5-section outline (Hook, Problem, Value/Lesson, Solution, CTA)\n- **Output**: Structured framework for final post\n- **Models**: GPT-4o-mini or Gemini 2.5-flash\n\n**Stage 3: Post Generator Agent (RAG)**\n- **Input**: Post structure + topic\n- **RAG Process**:\n - Queries Supabase vector store for 5 most similar viral posts\n - Analyzes patterns: hooks, storytelling, CTAs, engagement metrics\n - Identifies optimal length, formatting, and emotional triggers\n- **Output**: Complete LinkedIn post applying viral patterns\n- **Models**: GPT-4o-mini or Gemini 2.5-flash with GPT-5-NANO for structured output\n\n**Stage 4: Publication**\n- Auto-publishes to LinkedIn via API\n- Or returns formatted post text for manual posting\n\n---\n\n# How To Use\n\n## Setup\n\n### 1. Configure Supabase Vector Database\n- Create Supabase project\n- Create table: `linkedin_post` with vector column (1536 dimensions for OpenAI embeddings)\n- Enable vector extension: `CREATE EXTENSION vector;`\n- Update credentials in \"Upload Document\" and \"Supabase Vector Store\" nodes\n\n### 2. Set Up Telegram Bot (Module 1)\n- Create bot via [@BotFather](https://t.me/BotFather)\n- Get bot token and update \"On Telegram Message\" credentials\n- Start bot and get your chat ID\n- Activate workflow\n\n### 3. Configure OpenAI API\n- Add API key to \"Embeddings\" nodes (both modules)\n- Configure language model credentials (GPT-4o-mini, GPT-5-NANO)\n\n### 4. Set Up LinkedIn API (Optional for Module 2)\n- Create LinkedIn app with member permissions\n- Configure OAuth2 credentials in \"Create a post\" node\n- Or remove node to get text output only\n\n### 5. Access Web Form\n- Get form URL from \"LinkedIn Form\" webhook\n- Bookmark for easy access\n\n"
