How to set it up

Open template #2395 on n8n.io and click Use for free, or copy the template JSON and paste it onto an empty canvas in n8n.
Create 5 credentials under Credentials → Add credential: Google Drive, Supabase, Embeddings OpenAI, OpenAI Chat Model, Supabase Vector Store. Then open each of those nodes and pick the credential.
Check the model in the OpenAI Chat Model node. The template may point at a model your account can't use; swap it for one you have access to.
Click Execute workflow and step through each node's output to confirm the data looks right.
Toggle the workflow to Active so its trigger runs on its own.
