Acrobat AI vs PDFgear Chatbot

Earlier this year, Adobe released an AI-powered assistant feature called Acrobat AI in their renowned PDF editor Adobe Acrobat Pro in a bid to entice subscriptions.

To help PDF users evaluate this upgrade, we used the popular AI PDF summarizer PDFgear Chatbot for comparison in various criteria including processing speed, answer accuracy, limitations, etc., so you can have a better understanding of Adobe Acrobat AI.

To test their performances in summarizing and analyzing different PDF documents, we randomly picked 3 informative Wikipedia pages and downloaded them as PDF files.

Processing Speed

To evaluate the processing speed of PDF analyzation of each tool, we’ll mainly focus on the time spent from the end user accessing the AI assistant feature, to the time when the interactable analysis is completed and the overview appears.

Acrobat AI

Depending on the length of the PDF document, Acrobat AI generally takes 10 to 38 seconds to process a PDF document with 10 to 60 pages.
In our testing, Acrobat AI takes around 10 seconds to process a 10-page PDF file and around 38 seconds for a PDF document with 50 to 60 pages. The time required for the initialization process is correlated to the length of the PDF document.
Previously analyzed files will be analyzed once again, taking the same time as the first time.

PDFgear Chatbot

PDFgear takes around 9 seconds to process PDF files, regardless of the length of the document.
The analysis overview of previously analyzed files can be accessed instantly, without needing processing all over again.

Verdict

In terms of PDF processing speed, PDFgear is significantly faster than Adobe Acrobat AI.

Accuracy Test	Pros	Cons
PDFgear Chatbot	Faster and more concise answers. Straight to the point, additional information when necessary. Better logic.	Poorer readability. Answers in paragraphs.
Acrobat AI	Answers in bullet lists with better readability.	Worse context. Contradictory, redundant information.

Test File 1: Computer science – Wikipedia

Q1: Summarize this PDF

Two AI tools both provide correct answers but in different styles.
PDFgear offers more concise answers, with key information covered. It summarizes the entire PDF into two parts, one is about computer science (basic fields, history, and related disciplines), and the other one is historical figures.

Accuracy Computer Science PDFgear

Acrobat AI’s answer is much longer, with seven paragraphs and a total of nearly 500 words.
However, most of the key information has already been covered in the first three paragraphs. The following content is not a summary, but more like an outline, explaining each keyword again.
It talked about the theoretical disciplines, iconic historical figures, research fields, research results, and strong correlation with mathematics included in computer science.

Accuracy Computer Science Adobe

Verdict: While Acrobat AI provides more detailed summaries of the content, PDFgear is a qualified AI PDF summarizer regarding the accuracy of answers.

Q2: What is the significance of the Turing Machine in Computer Science?

Both answers are correct, but the styles are distinctively different.
PDFgear’s answer is still more concise. This answer is more useful when a summary is needed without detailed technical details.

Turing Machine PDFgear

Acrobat AI’s answers are more informative, and the detailed content may be more valuable to readers with professional backgrounds.
Subsequently, I continued to ask PDFgear for a more detailed follow-up to this question and Acrobat for a more concise answer. In that case, Acrobat AI made a mistake and it shortened the first question (that is, summarize this PDF).

Turing Machine Adobe

Verdict: Acrobat AI falls short in handling continuous conversations, but this problem did not occur again in later tests, so it could be a sporadic issue. However, PDFgear did not have that problem during the entire test.

Q3: What are some notable inventions or advancements that were significant in the development of Computer Science?

In terms of the answer’s format, they both support answers in a bullet list, but Acrobat AI sports more intuitive answers with better readability.

Notable Inventions PDFgear

In terms of content quality, Acrobat AI delivers more comprehensive summaries, with 5 more key points than PDFgear, which are indeed information mentioned in the document.

Notable Inventions Adobe

However, Acrobat AI’s ampleness of key points could be the result of extended answers.

Test File 2: Industrial Revolution – Wikipedia

Q1: When and where did the first Industrial Revolution begin?

First Industrial Revolution PDFgear

Acrobat AI and PDFgear both provide the technically correct answer, while PDFgear turned out to be more precise by providing the specific year information.

First Industrial Revolution Adobe

Q2: Can you describe how the Industrial Revolution led to urbanization?

Both answers are correct. PDFgear’s answer is still the more concise one, while Acrobat AI’s answer is longer but with a clearer layout.

Led to Urbanization PDFgear

They both mentioned relevant key points, but PDFgear prevails with more logical answers, explaining the question from the cause to the effect.

Led to Urbanization Adobe

On the other hand, Acrobat AI’s plain-vanilla bullet-list answers that lack logical explanation will make users harder to understand the answer.

Q3: Who were some key figures or contributors to the Industrial Revolution?

Both the answers are correct. PDFgear only picked a handful of characters to talk about, while Acrobat AI almost covered all the characters mentioned in the article.

Significance of Microsoft Office PDFgear

In addition, Acrobat AI’s answers layout does look better.

Significance of Microsoft Office Adobe

When I asked them again to list important figures and corresponding inventions, PDFgear merely adjusted the layout of the previous answer.

Answer Format PDFgear

Acrobat AI removed 3 characters it “deemed less critical” and still retained 12.

Answer Format PDFgear

It seems that PDFgear is more readable, but Acrobat AI’s answers provide more information.

PDFgear has a little less content and is missing some important figures for the Industrial Revolution, while Acrobat has a little too much content, and those with mere achievements are also listed.

Verdict: I personally think that this round is a tie. The accuracy of answers to Q3 varies from person to person.

Test File 3: Microsoft – Wikipedia

Q1: Who were the founders of Microsoft and when was it established?

Founders of Microsoft PDFgear

All correct and no-nonsense. PDFgear has an obvious advantage in answering speed, taking only about 3 seconds, while Acrobat AI approaches 10 seconds.

Founders of Microsoft Adobe

Q2: Can you list some acquisitions made by Microsoft and how they influenced Microsoft’s portfolio?

Acrobat AI is better in terms of comprehensiveness and readability of answers.

Microsoft Acquisitions Adobe

Since PDFgear doesn’t read the entire PDF (resulting in the faster answering speed), the answers here aren’t as comprehensive as Acrobat.

Microsoft Acquisitions PDFgear

Q3: What is the significance of Microsoft Office in the company’s growth and what are its key components?

The answers are both correct, but Acrobat AI has a less detailed answer this time.

Key Components Adobe

In terms of the accuracy of answers, PDFgear is better. In addition to answering questions, it also gave a brief introduction to the functions of several commonly used components in Office, while Acrobat AI failed to.

Key Components PDFgear

Verdict: Overall, although the accuracy of Acrobat AI’s answers is pretty good, it is very likely that there will be some redundant information that is not relevant to the question. The thinking logic is not very strict.

Adobe Consistency

PDFgear Chatbot’s answers are in most cases direct answers, followed by a brief explanation of the content if necessary, and there is less chance of irrelevant redundant information.

PDFgear Consistency

According to the answers to Q3, Microsoft Office was released in 1989. I further expanded on that year information and asked questions, and Acrobat AI gave contradictory answers.

The first answer was that Office was first released in 1989, the second answer was 1990, and the third answer changed it to 1989.

There’s no information source provided, and the accuracy of the answers is not very stable.

PDFgear’s answers remain consistent in 1989.

Reliability of the Answer

Acrobat AI is the winner here.

While PDFgear has accurate answers, its unreliable information sources are unfriendly to users.

PDFgear Reliability

On the other hand, Acrobat AI will mark the source in the answer, precisely leading you to a sentence or even a phrase.

PDFgear Reliability

However, the source accuracy of Acrobat AI is not very high (around 50%). For example, source 2 in the screenshot is actually completely irrelevant information.

Adobe Incorrect Source

Although PDFgear will provide sources, the accuracy rate is not as high as Acrobat AI (around 30%).

In addition, since PDFgear can not point precisely to sentences or phrases, it is actually difficult to find the exact source when jumping to a certain page.

Miscellaneous

PDFgear Chatbot and Acrobat AI functions in summarizing and analyzing PDF documents are similar.

Additionally, PDFgear Chatbot also allows for PDF editor software interaction such as “compressing the PDF”, “zooming in PDF view”, “displaying PDF in slide mode”, etc.

Acrobat AI is not subject to PDF conversions, yet it’s worth mentioning that the 1-click copy button for answers is extremely useful.

In that case, PDFgear Chatbot wins at providing extensive features.
