ChatDOC-The Best PDF AI Reader in 2024

As mentioned above, a qualified PDF AI tool should cater to multiple aspects simultaneously. Based on this foundation, we recommend ChatDOC for you, a product that excels in this field. You might be wondering what makes ChatDOC outstanding among so many similar products. Here, we will introduce what ChatDOC can analyze.

Text analyze

Text analysis seems to be the most basic function for all kinds of PDF AI tools, including ChatDOC. However, it is not as simple as it may seem. Many other tools face challenges such as information omission or errors and cannot handle multiple documents simultaneously. This causes trouble for users as they have to double-check for accuracy and duplicate uploads of several PDFs.

Our team has acknowledged all the inconveniences and diligently worked on precise recognition to enhance user experience. It's also noteworthy that ChatDOC supports analyzing entire passages as well as specific sections. Information within PDFs is segmented naturally, allowing users to easily select specific areas of focus and receive instant answers within the paragraph.

Table analyze

Click on the small icon next to the table, and ChatDOC will extract the data into the chatbox, preserving its structure and allowing you to make queries about it.

Image analyze

Click on the camera icon at the top left and use a magic pen to outline the image. Let ChatDOC analyze the elements in the image and draw a final conclusion for you.

Formula analyze

It also works on formulas in PDFs. Click on the 'FX' button at the top left and box-select the formula you're confused about.

Cross-document analyze

ChatDOC supports handling multiple PDFs simultaneously. Create a new collection and select the ones you need to analyze.
