Create AI-ready vector datasets from web content with Claude, Ollama & Qdrant

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.

2. Set Up Scrapeless

1. Register at: Scrapeless
2. Copy your API token
3. Paste the token into the HTTP Request node labeled "Scrapeless Web Request"

---

3. Set Up Claude API (Anthropic)

1. Sign up at Anthropic Console
2. Generate your Claude API key
3. Add the API key to the following nodes:

4. 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

5. 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

6. 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
