Introduction

This is an example implementation of Slack-GPT, A simple starter for a Slack app / chatbot that uses the Bolt.js Slack app framework, Langchain, openAI and a Pinecone vectorstore to provide LLM generated answers to user questions based on a custom data set.

This example connects to confluence and ingests and embeds all of it's pages, in order to act as a helpful HR assistant bot for a company.

This example provides a start to finish solution for how to converse with your own data in Slack using Chat-GPT, Langcahin, Pinecone and Bolt.js.
