ChatPDF Alternatives (2023)

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 apps to chat with your pdfs is It is one of the first apps of its kind in the space, but over time there have been lots of other competitors that have appeared.

This article will go over the best alternatives in 2023 that you might be interested in purchasing instead. Features And Pricing

Attached below is an image of the various features that the different pricing plans offer.

2) Nexus

Nexus is another popular pdf chat app that is slightly different compared to and

First is the pricing. Nexus is $7/month or $50/year so it is significantly cheaper compared to or ChatGPT Plus (the 3rd alternative which we will do a deep dive into next). This is by far the best option for budget-conscious individuals.

Next up is the different features that it offers.

Rather than being only a pdf-chat app, it is more of a general note taking tool by offering you a place to take manual notes on the side in addition to having a separate tab to chat with the pdf. It is much more of a hybrid product of a traditional manual note taking that has a sprinkle of AI throughout it when you need the additional assistance.

You can organize your papers into "projects" and you can take notes that are shared throughout the entire project or you can also take notes specifically to one individual paper.

Lastly is the unique feature of multi-paper chats. This feature lets you ask one question to multiple papers at once, letting you compare and contrast the answers between all of the papers. Then, when you want to do a deeper dive into a specific paper, you can press the "learn more" button to move into a 1:1 chat conversation with the paper.

3) ChatGPT Plus

The last alternative to ChatPDF is ChatGPT Plus. ChatGPT Plus costs $20/month and does not have any discounts for annual plans.

ChatGPT Plus gives you the ability to upload a PDF and chat with it directly without any limits associated with it.

The biggest benefit of using ChatGPT Plus directly is the fact that it unlocks way more features outside of chatting with a PDF. It offers you the ability to create your own custom GPTs (chat models), code interpreting, browse the web from within the chat interface, and so much more.

ChatGPT Plus is a little different compared to the other products mentioned in this article because the other products were built specifically to chat with PDFs (and in the case of Nexus built specifically to chat with PDFs AND take notes) whereas ChatGPT Plus is a general purpose chat interface that can do thousands of different things, and having the ability to chat with a PDF is just one of the may features that it can do.

While ChatGPT can do everything, the learning curve to figure out how to set everything up is significantly higher compared to the other alternatives.


In my opinion there are clear situations on when to use ChatPDF,, Nexus, and ChatGPT Plus.

If you want to chat with PDFs to write papers such as essays or reports, is the best option for you since it gives you unlimited access to

If you are looking to chat with PDFs within a team with private documents and you need access to an API that lets you chat with a document in your own applications that you are trying to build, then is the best choice for you.

If you are looking to chat with PDFs and to take notes at the same time OR you are more budget conscious, then is the best option for you since it is significantly cheaper than any other option and it lets you manually take notes in addition to chatting with the PDF.

Lastly, if chatting with a PDF is one small thing you need to do and you want the most robust chat ecosystem, then ChatGPT plus is the best option for you.
