About This Workflow
Overview
This n8n workflow is designed to automate the creation of podcast show notes. It takes raw podcast transcripts as input, processes them using Langchain components for text splitting and embedding generation, and then stores these embeddings in a Supabase vector store. A Langchain agent orchestrates the retrieval of relevant information from the vector store and generates concise show notes. Finally, the generated notes are logged to a Google Sheet for easy access and review. This workflow solves the problem of manually transcribing, summarizing, and formatting podcast content, saving significant time and effort.
