First of all you must clone the repository:

git clone https://github.com/jezbravo/pdf-chat.git
cd django-chatbot

Create a virtual environment to install dependencies in and activate it:

python.exe -m venv venv
.\venv\Scripts\activate

Then install the dependencies:

(venv)pip install -r requirements.txt

Note the (venv) in front of the prompt. This indicates that this terminal session operates in a virtual environment set up by "venv".

Environment Variables

In order for the program to work correctly, it is necessary to configure the following environment variable in an .env file at the root of the project:

GOOGLE_API_KEY=

This key is provided by the Google Gemini API service.

Once everything is ready:

(venv)streamlit run .\app.py

Demo

A PDF file can be uploaded by pressing the "Browse files" button in the sidebar. It is worth mentioning that the maximum size that the file can have is 200 MB. Then press the "Submit & Process" button and wait a few seconds for the application to scan the document. Once the "Done" notice appears, the form on the main screen will be ready to begin receiving questions related to the recently uploaded file.
