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 Nexus.

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

Price

Nexus has a simple pricing structure of $7/month or $50/year for its paid plan and they also have a forever free plan.

Features

The free plan on Nexus is slightly different compared to other popular pdf chat tools like pdf.aiand ChatPDF. In pdf.ai and ChatPDF you just upload your papers into the software, but with Nexus your papers are organized into research projects and you can upload individual PDFs into each research project.

Under the free plan of Nexus, you are able to create one research project and within each project you can upload a total of 2 papers per project, and then you can ask an unlimited number of questions to each PDF.

When you go to chat with your papers, there is also a designated section where you can take notes while reading your paper. You can take notes that are shared throughout the entire project or you can take notes about that specific paper that you are reading — a feature that neither chatpdf.com or pdf.ai has.

Lastly, Nexus has a unique multi-paper chat feature which lets you ask one question to multiple papers at once, allowing you to compare and contrast answers between multiple papers. Then, if you see an interesting answer, you can dive into a 1 on 1 chat with that paper to learn more details about it.

Who Should Subscribe To Nexus?

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.

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, Nexus is the best tool for the job. 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.
