As a substitute, it analyzes the knowledge supplied from the PDF and makes use of that as its context to offer a very new reply.

I additionally questioned what would occur if I requested ChatPDF a query unrelated to the PDF file I used. Unsurprisingly, it didn’t present any actual reply — as an alternative, it defaulted to a generic response about not having sufficient info on the subject material.

Should you create an account, ChatPDF additionally grants you entry to a chat historical past which incorporates all of your previous conversations with the chatbot. 

Options of ChatPDF

ChatPDF is a barebones software. Right here’s a rundown of its few options:

ChatPDF Alternate options

ChatPDF isn’t the one AI mannequin that may reply questions based mostly on an uploaded PDF file. Listed here are different chatbots to contemplate:


ChatGPT doesn’t want one other introduction, however I’ll give one anyway. This AI chatbot took the world by storm in its public launch, and is extensively thought-about as the start line of this new period of AI. The premise is easy: give a immediate, obtain a solution. Regardless of the quite a few controversies surrounding its firm, ChatGPT continues to be the most well-liked alternative of LLM for a lot of.

One among ChatGPT’s latest options is multimodal prompts. This implies receiving prompts in any format, whether or not it is spreadsheets, photographs, and even PDF recordsdata. 

So, is it value it to make use of ChatPDF over ChatGPT? It relies upon.

One of many issues that ChatPDF has that ChatGPT doesn’t is that the core performance (importing PDF recordsdata) just isn’t locked behind a paywall. The latter solely means that you can use PDF recordsdata as prompts once you’re utilizing ChatGPT Plus, which prices about $20 monthly.

Nevertheless, you get a lot extra in that $20. ChatGPT Plus can analyze every part in a PDF file, even photographs. It’s additionally rather more correct in responding utilizing the knowledge supplied within the uploaded doc. You possibly can even mess around with ChatGPT’s many options — for instance, you may generate photographs based mostly on info in that PDF file or reply math questions utilizing the Wolfram Alpha extension in ChatGPT Plus.

What’s extra is that Claude 3’s benchmarks showcase higher outcomes than most of its counterparts. This implies you may belief that Claude is extra correct in its responses even with bigger PDF recordsdata.

The Backside Line

Let’s return to the query posted within the title: Is ChatPDF nonetheless value making an attempt?

To me, the reply is no.

In comparison with different LLMs that allow you to add PDF recordsdata like ChatGPT, ChatPDF is lacking much more options that makes the appliance extra accessible and versatile. And in comparison with Claude, ChatPDF’s free model is much extra limiting and fewer correct.

The tough reality is that different AI fashions have utterly eclipsed ChatPDF in performance and accessibility. That’s why the reply is a strong no, ChatPDF is certainly not value making an attempt within the context of its rivals.
