What comes to your mind when you hear, “artificial intelligence?” Did you think about ChatGPT? Or image generation tools like Dall-E? While these are probably the most commonly casually used tools in AI, there is a lot more you can do with artificial intelligence.

In this article, I’m going to discuss the best AI PDF tools. If you’ve ever had to go through a long and boring PDF to extract information and wished you had some help, read up because I’ve got just what you need.

What is an AI PDF Reader?

An AI PDF reader is a software tool that uses artificial intelligence to “read” through PDFs. It uses deep learning and machine learning algorithms along with Natural Language Processing (NLP) to process files. It can quickly scan through the document and retrieve the information you’re looking for.

AI can summarize and extract information much faster than humans. What might take you hours will be done by AI in just a few seconds.

If you have a scanned PDF, AI can use optical character recognition (OCR) to identify text and extract relevant information. And once AI can read a PDF, it can interact with it just like it would interact with another piece of text.

Is it useful for you? Of course, it is. Whether you have to read invoices from suppliers, notes from teachers, or documents for office purposes, an AI document reader can be valuable for absolutely anybody.

Benefits of Using an AI PDF Tool

An AI PDF tool can be used in many industries, but I’m going to list just a few here.

Legal

Legal documents are long and heavy, and mistakes can be costly. With an AI PDF tool, you can extract information about court filings, contracts, and other documents. It also makes contract document analysis much easier. Did the other party make the right contract? Are the obligations and clauses in their place? What are the potential risks? An AI PDF reader online can find out exactly what you’re looking for.

Financial

Financial reporting is also long and tedious. There are chances of human errors that can be minimized with an AI PDF tool. It can extract accurate information from reports, statements, and invoices, making the job easier for finance analysts and accountants.

As you can see from these two examples, AI PDF reading makes the workplace more efficient. You can extract data like a pro, write creative summaries, and analyze content in a much faster way.

In a nutshell, it can help you make sense of data. Data that’s large and overly complicated. Simplify it by using AI and get just the right information you’re looking for.
