IronPDF vs ChatGPT - Extracting Text from PDF Documents

What is ChatGPT?

ChatGPT is a large language model-based chatbot released by OpenAI in 2022. It’s notable for enabling users to create and shape a dialogue into a desired structure, style, level of detail, and language spoken. Every discussion point takes into account a context that considers prior prompts and responses, or 'prompt engineering', using the OpenAI API key.

The foundation of ChatGPT is made up of transformer models which are part of OpenAI's exclusive generative pre-trained transformer series. These models are then optimized for conversational applications by combining supervised and reinforcement learning methods. Originally published as a free research preview, ChatGPT AI language model is now offered on a freemium basis by OpenAI due to its popularity. The more sophisticated GPT-4-based version and priority access to updated features are made available to paid customers under the brand name 'ChatGPT Plus,' while users can access its free tier using GPT-3.5.

Can ChatGPT Read PDF Files?

Well, yes and no. With the paid-for version, asking ChatGPT to extract text from a PDF document is as simple as uploading the file to the chatbox and asking it to extract text from or summarize the PDF contents.

However, it’s not without its drawbacks. ChatGPT will give you the information in plain text, meaning that it’s a manual process to create a new PDF document using that information. It’s possible to ask ChatGPT to create a new PDF file from the extracted text, but it’s prone to formatting issues and malfunctioning download links. Also, customization is limited with ChatGPT, frequently having issues with requests to add headers and footers to your documents, as an example.

As of writing, the free tier of ChatGPT doesn’t support file attachments, meaning it’s impossible to ask it to read PDFs.
