Part 4. ChatPDF vs. UPDF: Detailed Comparison

Looking at the capabilities and offerings of ChatPDF vs. UPDF, both seem to offer similar services. However, if we have a deeper look at their offerings, then there are many differences between them. Some of the key differences are as follows:

1. Limitations

Although ChatPDF and UPDF can chat with PDFs efficiently, they have a few limits, especially regarding how they offer the services in the free and paid plans. For instance, ChatPDF can handle only a 10 MB file in its free plan, while UPDF AI can handle max 100 MB file in its free plan. You can find all these limitations on their pricing plans.

2. Ease of Use

ChatPDF and UPDF AI provide a user-friendly interface powered through a convenient click-based approach. Their chat box assistant makes it easy to chat with the PDF with simple wording.

However, UPDF AI takes the convenience game to a whole new level with its direct selection of text from the document to summarize/translate/explain. This implies that when you select any text, it provides a small pop-up window allowing you to summarize, translate, or explain the text right away.

ChatPDF and UPDF AI offer many similar features because both are powered through ChatGPT and provide an AI chat box. They both can:

  • Summarize
  • Translate
  • Explain
  • Rewrite/Write
  • Answer general questions

However, UPDF AI offers many additional features. It is part of the UPDF toolkit, which provides many other PDF editing features. With UPDF, you can also edit text/images/links directly from PDF, annotate, organize, and even convert PDF into other formats - these are all accessible in the free trial. In short, you get a complete experience of chatting with PDF and getting PDF editing capabilities under one roof.

4. Supported Formats

ChatPDF only supports the PDF format. On the other hand, UPDF AI supports multiple formats, including:

UPDF's "create" feature allows you to create a PDF from other formats and then use its AI assistant to chat with the converted PDF.

5. Chart Analysis

ChatPDF and UPDF AI are both able to analyze charts and extract insights from them. However, UPDF AI has a more advanced chart summarization feature. For instance, we took the Apple financial report and asked ChatPDF to “summarize this PDF within 100 words, including 5 points”. Although it did provide a summary, it was not in-depth and did not include the 5 points. The results gave a gesture that it just pulled the most relevant paragraphs when providing answers to prompts.
