When you think about PDFs you often think of pages of text. While most of them are just that, PDFs often also contain images, graphs and non selectable (scanned) text. Before the advent of AI, it used to be really hard to read the whole content of PDFs.
Fortunately, the latest AI models, such as GPT-4o, are excellent at reading and visually recognising whole documents contents.
GPT-4o is your best choice when it comes to working with pdfs. It both can read the text and use OCR visual recognition to convert handwritten and scanned text to digital files.
One of the most interesting things you can do after analyzing the pdf with AI is to use it to learn and check your knowledge. You can use AI to generate am interactive quiz or even talk to your pdf and have the AI answer questions for you.
The simplest thing for the AI is to copy the selectable text. It doesn’t really require any artificial intelligence. What is harder is to analyze scanned or photographed text, that’s when the AI shines. It’s able to visually recognise letters and convert it to digitized text. The same applies to images and graphs - GPTs visual capabilities let you ask it what the picture represents.
After uploading a file, you can ask the AI any question about the PDF, you’ll get an answer based on the document you uploaded.
You can also use the AI to generate a quiz, and let it question you.
If you want a more pleasant and advanced experience try out PDFQuiz’s quizmaker - it’s specifically made for that purpose.
ChatGPT in free version doesn’t let you upload files. You need a paid subscription to the Plus version to be able to analyze PDFs.
It’s very hard to find free tools that let you do that. PDFQuiz offers a free basic plan where you can upload a PDF and have it analyzed by GPT-4o mini.
