This is a simple demo using Langchain, OpenAI and Chroma.
To run this demo, you need to have:
- A Chroma client using Docker - docs.trychroma.com.
- 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-collectionexists, 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.
