🔹 Can ChatPDF speak my language?
Yes, ChatPDF can read PDFs and answer questions in any language. You can upload a PDF in one language and ask questions in another. The greeting message will be in the PDF’s language. After that, ChatPDF will answer in the language you ask. If a message isn’t in the language you want, just ask ChatPDF to change it.
🔹 Is ChatPDF free?
ChatPDF allows you to use it for free with 2 PDFs every day, each up to 120 pages. For more, you can upgrade to the Plus plan. For additional information, check the pricing page.
🔹 Can I chat with multiple PDF files at the same time?
You can! Create a folder and drag multiple PDFs into it. Then, click on the folder to chat with all PDFs at once. Creating a folder only works on a desktop computer, not from a phone.
🔹 Are my files secure?
ChatPDF will never share your files with anyone. They are stored on a secure cloud storage and can be deleted at any time.
🔹 How do I delete a PDF from ChatPDF?
From Chat view: click gray Delete Chat button on the top right. From the Home page: click the X next to the chat title in the My Chats section. This will permanently delete the chat and PDF file content from ChatPDF servers.
🔹 Why can’t ChatPDF see all PDF pages?
For each answer, ChatPDF can look at only a few paragraphs from the PDF at once. These paragraphs are the most related to the question. ChatPDF might say it can’t see the whole PDF or mention just a few pages because it can view only paragraphs from those pages for the current question.
🔹 How does ChatPDF work?
In the analyzing step, ChatPDF creates a semantic index over all paragraphs of the PDF. When answering a question, ChatPDF finds the most relevant paragraphs from the PDF and uses the ChatGPT API from OpenAI to generate an answer.
🔹 Can ChatPDF understand images and tables in PDFs?
ChatPDF can not yet read images in the PDF, including images that consist of scanned text. Text in tables is read by ChatPDF, but it might have problems correlating the correct rows and columns.
🔹 Does ChatPDF use GPT-4?
ChatPDF uses GPT 3.5 for now, which is the same as ChatGPT. We are looking at how to add GPT-4. But GPT-4 won’t be available for all messages on the free plan because it costs too much.
🔹 What is the cancellation policy?
You can cancel your Plus subscription at any time. If you cancel, you will still have access to your Plus plan until the end of the current 30-day billing period. To cancel your subscription, click on My Account.
🔹 Is there an API to integrate ChatPDF?
You can integrate ChatPDF into your website, mobile app or use it via an API from your backend. Check out the API Documentation to learn more.
