AI is currently changing the world in terms of how we all do work, and one of the most popular ways that people use AI is to chat with a PDF or text document to quickly extract information without having to read the entire text document end-to-end. This is useful for both students and employees at companies alike because we all know reading and extracting information takes an incredibly long time.

One of the most popular tools in this space is pdf.ai

In this article will review the main features of pdf.ai to help you determine whether it is the best tool for you.

Who Should Subscribe To PDF.AI?

We'll be the first ones to say that no matter which pdf chat software you choose, they will all do a great job of chatting with the PDF to help you extract insights much more quickly compared to if you were reading the PDF yourself.

PDF.ai is the best option if you are someone that is looking for a chat PDF website that also provides you with a chat PDF API (helpful if you are a developer) or if you are someone that wants to be able to share your PDF chats with other people (within a company or a group project, for example).

If you are looking for a chat pdf software that also helps provides you access to an AI writing tool, ChatPDF is the best option as you get access to jenni.ai when you upgrade to ChatPDF Plus — no other pdf chat software provides you with that ability. (Click here to read our ChatPDF review)

If you are someone that is looking for a PDF chat website that lets you take notes and chat with your PDF at the same time, you might want to look into Nexus. It's a much more "hybrid" solution that lets you take notes and chat with your pdf all in one website rather than only letting you chat with your PDF. Nexus also offers multi-paper chat which lets you ask one question to multiple papers at once, allowing you to compare and contrast answer between multiple papers. Also, Nexus is significantly cheaper compared to PDF.ai and ChatPDF as it comes in at only $7/month or $50/year. (Click here to read our Nexus review)
