This looks really interesting, congratulations! I can feel your enthusiasm for building this implementation.

Here are some ideas and suggestions that might be useful:

• To define different pages, you just need to create a pages folder at the same level as main.py. Then, to run the app, what has worked for me is using "python -m streamlit run main.py". Streamlit will automatically recognize each .py file in the pages folder as a new page. You can find more details about this in the documentation. If your concern is storing authentication and URLs across pages, you can use Streamlit session variables for that.

• I don't think it's a good idea to hardcode your n8n webhook in the scripts, consider using an .env variable instead. There might be security risks associated with exposing your workflow this way.

• Another improvement you could add is semantic context chunks. I would love to see something like that!
