[Bug]Chatbot gives responses irrelevant to the site

## Description
The chatbot answers all the questions it is asked irrespective of whether they are related to the site or not as evident in the screenshot example as well.

## Expected Behavior
The chatbot should:
- Only respond to queries related to the project/website domain
- Politely redirect off-topic queries
- Suggest relevant topics the bot can help with

## Proposed solution
Limiting the chatbot responses to the things related to the website will be more professional by filtering out the prompt given by the user and making instruct the ai behaviour to only answer questions specific to the project

I would be happy to work on this if assigned!
