AI-Powered Web Data Pipeline with n8n How It Works This n8n workflow builds an AI-powered web data pipeline that automates the entire process of: Extraction Structuring Vectorization Storage It integrates multiple advanced tools to transform messy web pages into clean, searchable vector databases. Integrated Tools Scrapeless Bypasses JavaScript-heavy websites and anti-bot protections to reliably extract HTML content. Claude AI Uses LLMs to analyze unstructured HTML and generate clean, structured JSON data. Ollama Embeddings Generates local vector embeddings from structured text using the all-minilm model. Qdrant Vector DB Stores semantic vector data for fast and meaningful search capabilities. Webhook Notifications Sends real-time updates when workflows complete or errors occur. From messy webpages to structured vector data — this pipeline is perfect for building intelligent agents, knowledge bases, or research automation tools. --- Setup Steps Install n8n > Requires Node.js v18 / v20 / v22 npm install -g n8n n8n After installation, access the n8n interface via: URL: http://localhost:5678 --- Set Up Scrapeless Register at: Scrapeless Copy your API token Paste the token into the HTTP Request node labeled "Scrapeless Web Request" --- Set Up Claude API (Anthropic) Sign up at Anthropic Console Generate your Claude API key Add the API key to the following nodes: Claude Extractor AI Data Checker Claude AI Agent --- Install and Run Ollama macOS brew install ollama Linux curl -fsSL https://ollama.com/install.sh | sh Windows Download the installer from: https://ollama.com Start Ollama Server ollama serve Pull Embedding Model ollama pull all-minilm Install Qdrant (via Docker) docker pull qdrant/qdrant docker run -d \ --name qdrant-server \ -p 6333:6333 -p 6334:6334 \ -v $(pwd)/qdrant_storage:/qdrant/storage \ qdrant/qdrant Test if Qdrant is running: curl http://localhost:6333/healthz Configure the n8n Workflow Modify the Trigger (Manual or Scheduled) Input your Target URLs and Collection Name in the designated nodes Paste all required API Tokens / Keys into their corresponding nodes Ensure your Qdrant and Ollama services are running Ideal Use Cases Custom AI Chatbots Private Search Engines Research Tools Internal Knowledge Bases Content Monitoring Pipelines
