Since ChatGPT broke out in the first year of artificial intelligence AI in 2023, there are now many plug-ins and application services that can be used. For example, WeChat allows ChatGPT to have an Internet connection to lift the time limit. Through AIPRM for ChatGPT, you can have hundreds of command spell templates to apply. Or you can integrate ChatGPT into the LINE chat room, and with the help of AI tools, you can solve problems in work or life more quickly.
This time I want to share a more powerful ChatGPT free tool,“ChatPDF” is a ChatGPT robot tool that can analyze PDF files, and analyze the content of documents with high efficiency. Whether it is an operation manual, business proposal, e-textbook, lecture notes or academic articles, etc., you can understand the content through ChatPDF. It can save the time of turning pages to read all the materials.
What is ChatPDF?
The ChatPDF service mainly integrates the ChatGPT API so that it can directly analyze the PDF content. After uploading the PDF file, you can ask about the content and key points of the file through the dialog window. It is a practical tool that can quickly analyze and summarize the content.
However, ChatPDF still has many restrictions. If you want to use ChatGPT to parse PDF files, you should pay attention to the following issues:
- ChatPDF can only recognize text but not analyze images (no OCR recognition yet).
- A maximum of 120 pages of PDF files are supported for free (it is recommended to use other PDF tools to split first), and fees will be charged for more pages.
- The maximum limit for a single PDF file is 10MB, and only 32MB can be paid for.
As for uploading the PDF data of ChatPDF, the official claims that it will try its best to avoid the security and privacy of the PDF file, and it will be automatically deleted after seven days of storage on the server.

Besides ChatPDF can be used for free, there is also a paid subscription version of ChatGPT. The differences in functions and restrictions are as follows:
