This is a simple demo using Langchain, OpenAI and Chroma.

To run this demo, you need to have:

1. A Chroma client using Docker - docs.trychroma.com.
2. An OpenAI account. If you don't have one, you can sign up for free at openai.com.

A simple chatbot to interact with any website that you enter in the top input field. In local development only.

After you enter a URL to crawl:

• if website-collection exists, is deleted. This is so you are only having a conversation with info from one site.
• url entered and urls found in crawl will be broken up into chunks and embeddeding to store in Chroma vector db as website-collection
• chat is now ready to ask questions about the site.

git clone git@github.com:chroma-core/chroma.git
cd chroma
docker-compose up -d --build

2. Clone this repository

git clone https://github.com/e-roy/langchain-chatbot-demo.git

3. Install dependencies
