However now, with in style chatbots reminiscent of ChatGPT and Claude permitting multimodal prompts, does ChatPDF nonetheless have an area within the evolving AI market?

ChatPDF is a reasonably easy software. All you’ll want to do is put together a PDF file. For the sake of this instance, I’m utilizing an previous reviewer as my enter. To begin, click on the “Drop PDF Right here” discipline within the entrance web page, then choose your PDF file.

As a substitute, it analyzes the knowledge supplied from the PDF and makes use of that as its context to offer a totally 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 data on the subject material.

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

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 primarily based on an uploaded PDF file. Listed here are different chatbots to think about:


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 of as the start line of this new period of AI. The premise is straightforward: give a immediate, obtain a solution. Regardless of the quite a few controversies surrounding its firm, ChatGPT continues to be the most well-liked selection of LLM for a lot of.

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 information) shouldn’t be locked behind a paywall. The latter solely permits you to use PDF information as prompts if you’re utilizing ChatGPT Plus, which prices about $20 per 30 days.

Nonetheless, you get a lot extra in that $20. ChatGPT Plus can analyze all the pieces in a PDF file, even photos. It’s additionally way more correct in responding utilizing the knowledge supplied within the uploaded doc. You may even mess around with ChatGPT’s many options — for instance, you’ll be able to generate photos primarily based on data in that PDF file or reply math questions utilizing the Wolfram Alpha extension in ChatGPT Plus.


If not ChatGPT, then why not Anthropic’s entry to the LLM sport: Claude. Regardless of its comparatively late launch date, this chatbot is slowly gaining traction within the AI world for its good mixture of ethics, accuracy, and intelligence.

The Backside Line

To me, the reply is no.

In comparison with different LLMs that allow you to add PDF information 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 way extra limiting and fewer correct.

The cruel reality is that different AI fashions have fully eclipsed ChatPDF in performance and accessibility. That’s why the reply is a stable no, ChatPDF is certainly not value attempting within the context of its rivals.
