Workflow Description

An advanced retrieval-augmented generation system that pulls live data from Notion and Supabase, processes it with OpenAI embeddings, and returns contextually accurate answers. The template chains multiple AI components to enable intelligent document search and question-answering workflows.

How it works

  1. 1.Load documents from Notion or Supabase and split them into manageable text chunks using token-based splitting
  2. 2.Generate vector embeddings for all content segments via OpenAI models and persist them in the Supabase vector store
  3. 3.Accept user queries through a chat interface and retrieve relevant documents, then synthesize answers using LLM chains

Use cases

  • Build a customer support chatbot that answers questions by searching a constantly updated knowledge base
  • Create an internal search engine for organizations to query policies, documentation, and structured data across multiple sources

Requirements

  • Valid OpenAI API key with access to embedding and chat models
  • Supabase account with a configured vector database and proper read/write permissions

Service Value

Ideal as a smart automation service combining integrations and AI to produce ready-to-use results.
