Pinecone will store your knowledge embeddings in different namespaces.

Create Pinecone Account & Index

1. Sign up at Pinecone
2. Create a new index named "cosmos" with the following settings:
   • Dimensions: 1536 (matches OpenAI's embedding size)
   • Metric: Cosine (best for semantic similarity)
   • Model: text-embedding-3-small
3. Note your API key from the Pinecone dashboard - you'll need this for n8n

The index will automatically create namespaces for different knowledge domains:

• ai_news
• ai_prompts
• ai_tools
• personal_business
