Seed a Supabase AI knowledge base from Notion with Ollama embeddings
Ready for 3.0Ready for 3.0. This template uses no nodes that n8n 3.0 removes. No removed nodes, versions or helpers found. Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 11 nodes and runs manually, when you click “Execute workflow” (plus 1 other trigger). Along the way it connects Notion, Supabase Vector Store and Embeddings Ollama.
How it runs
Trigger: Manually, when you click “Execute workflow” (plus 1 other trigger).
- Remove Existing Embeddings (HTTP Request): calls an HTTP API (DELETE)
- Get Notion Pages (Notion): get many (database page)
- Fetch Page Blocks (Notion): get many (block)
- Aggregate Block Text (Code): runs custom JavaScript code
- Skip Empty Pages (If): checks a condition and branches into true / false
- Insert into Knowledge Store (Supabase Vector Store): stores documents in the Supabase vector store, with embeddings: Generate Embeddings Ollama; document loader: Load Default Data
Services it uses
Before you upgrade to n8n 3.0
Nothing in this workflow is removed in n8n 3.0, so it should import and run after the upgrade.
