Performance Analysis of ChatDOC

Now that we know the basics about ChatDOC and its main features, let's bring it into a real test. We will take an IEEE research article as a test case and evaluate ChatDOC efficiency by asking different queries, such as summarize research article, explain a few concepts, etc.

After uploading and opening the research article on ChatDOC, it greeted us with a concise abstract, providing a quick overview of the whole document. Afterward, we asked it to summarize the whole research article.

ChatDOC was able to analyze the whole article and provide a decent summary. However, the level of detail in the summary was limited compared to what UPDF AI offers when asked to summarize.

So, either you ask ChatDOC again and ask it to provide a "detailed summary" or download UPDF to get a more in-depth summary in the first shot.

After the summary test, we decided to test its concept elaboration capabilities. So, we asked it to clarify "what is machine learning".

ChatDOC managed to provide a decent answer to our query, providing a general idea of machine learning.

Since ChatDOC supports multiple languages, we decided to ask the same question and let it be answered in French. However, it showed an error message.

According to ChatDOC features, it can help us "uncover deeper knowledge". So, we asked it to answer, "what is the origin of COVID-19", as the document did not answer this question directly. However, it responded that this document does not provide information about it.

Moreover, we tried to switch the "Stick to file" toggle so that it could answer outside the document scope, but it didn't allow us to switch.

In contrast, UPDF AI offers a separate chat window for general chats outside the scope of the document, making it easy to do question-answer on almost any topic. Download UPDF if you want to have both document-related and general topic chats using the AI assistant.

After doing different tests on ChatDOC AI, we can say that it can assist in reading documents, and its chat box can help answer document-related questions. However, it is not a friendly article summarizer and requires a learning curve to efficiently write commands and use the full potential of its chat box.
