The tool takes a text file and creates a summary from it.
It starts by running the text (for each page) from the PDF file through the PyPDF2 library. The script then ensures that no section of text is longer than 4000 characters (a good length for a text that can be passed to the OpenAI API). The script then passes each chunk of text to the OpenAI API with a prompts.
The summaries for each chunk are collected, recombined (respecting the 4000 character limit) and the process repeated.
This is done until only one chunk remains. The final summary is then returned.
