A language model can only read so much at once, so a long document has to be split before it can be used for retrieval or summarising. Doing that badly is the usual reason answers come out confused.
Each chunk repeats a little of the one before it. Cutting cleanly would split sentences in half and leave both pieces meaningless, so the overlap keeps the edges readable. Every chunk records which pages it came from.

Smaller for retrieval, larger for summarising.
Each chunk repeats this much of the one before it.
Ready to loop over in your own script.
It reads the text out of your PDF and splits it into chunks of a size you choose, as JSON. Each chunk records which pages it came from, so an answer can be traced back to a place in the document.
Because cutting cleanly at a word count splits sentences in half, and a sentence split across two chunks is useless in both. Repeating a little at each edge keeps them readable. It is standard practice and the reason retrieval works at all.
Around 300 to 500 words suits most retrieval setups: small enough to be specific, large enough to carry context. Larger chunks suit summarising. If you are unsure, the default is a sensible middle.
The JSON is ready to loop over in a script. What you do with each chunk, whether embedding it or passing it in a prompt, is up to your own setup.
